Migration Steps

  • Update the @babel/runtime npm package to version 7.0.0 or later:
    meteor npm install @babel/runtime@latest

Changes

  • Although Node 8.12.0 has been released, Meteor 1.8 still uses Node 8.11.4, due to concerns about excessive garbage collection and CPU usage in production. To enable Galaxy customers to use Node 8.12.0, we are planning a quick follow-up Meteor 1.8.1 release, which can be obtained by running the command

    meteor update --release 1.8.1

    Issue #10216

  • Meteor 1.7 introduced a new client bundle called web.browser.legacy in addition to the web.browser (modern) and web.cordova bundles. Naturally, this extra bundle increased client (re)build times. Since developers spend most of their time testing the modern bundle in development, and the legacy bundle mostly provides a safe fallback in production, Meteor 1.8 cleverly postpones building the legacy bundle until just after the development server restarts, so that development can continue as soon as the modern bundle has finished building. Since the legacy build happens during a time when the build process would otherwise be completely idle, the impact of the legacy build on server performance is minimal. Nevertheless, the legacy bundle still gets rebuilt regularly, so any legacy build errors will be surfaced in a timely fashion, and legacy clients can test the new legacy bundle by waiting a bit longer than modern clients. Applications using the autoupdate or hot-code-push packages will reload modern and legacy clients independently, once each new bundle becomes available. Issue #9948 PR #10055

  • Compiler plugins that call inputFile.addJavaScript or inputFile.addStylesheet may now delay expensive compilation work by passing partial options ({ path, hash }) as the first argument, followed by a callback function as the second argument, which will be called by the build system once it knows the module will actually be included in the bundle. For example, here's the old implementation of BabelCompiler#processFilesForTarget:

    processFilesForTarget(inputFiles) {
      inputFiles.forEach(inputFile => {
        var toBeAdded = this.processOneFileForTarget(inputFile);
        if (toBeAdded) {
          inputFile.addJavaScript(toBeAdded);
        }
      });
    }

    and here's the new version:

    processFilesForTarget(inputFiles) {
      inputFiles.forEach(inputFile => {
        if (inputFile.supportsLazyCompilation) {
          inputFile.addJavaScript({
            path: inputFile.getPathInPackage(),
            hash: inputFile.getSourceHash(),
          }, function () {
            return this.processOneFileForTarget(inputFile);
          });
        } else {
          var toBeAdded = this.processOneFileForTarget(inputFile);
          if (toBeAdded) {
            inputFile.addJavaScript(toBeAdded);
          }
        }
      });
    }

    If you are an author of a compiler plugin, we strongly recommend using this new API, since unnecessary compilation of files that are not included in the bundle can be a major source of performance problems for compiler plugins. Although this new API is only available in Meteor 1.8, you can use inputFile.supportsLazyCompilation to determine dynamically whether the new API is available, so you can support older versions of Meteor without having to publish multiple versions of your package. PR #9983

  • New React-based Meteor applications can now be created using the command

    meteor create --react new-react-app

    Though relatively simple, this application template reflects the ideas of many contributors, especially @dmihal and @alexsicart, and it will no doubt continue to evolve in future Meteor releases. Feature #182 PR #10149

  • The .meteor/packages file supports a new syntax for overriding problematic version constraints from packages you do not control.

    If a package version constraint in .meteor/packages ends with a ! character, any other (non-!) constraints on that package elsewhere in the application will be weakened to allow any version greater than or equal to the constraint, even if the major/minor versions do not match.

    For example, using both CoffeeScript 2 and practicalmeteor:mocha used to be impossible (or at least very difficult) because of this api.versionsFrom("1.3") statement, which unfortunately constrained the coffeescript package to version 1.x. In Meteor 1.8, if you want to update coffeescript to 2.x, you can relax the practicalmeteor:mocha constraint by putting

    coffeescript@2.2.1_1! # note the !
    

    in your .meteor/packages file. The coffeescript version still needs to be at least 1.x, so that practicalmeteor:mocha can count on that minimum. However, practicalmeteor:mocha will no longer constrain the major version of coffeescript, so coffeescript@2.2.1_1 will work.

    Feature #208 Commit 4a70b12e Commit 9872a3a7

  • The npm package has been upgraded to version 6.4.1, and our fork of its pacote dependency has been rebased against version 8.1.6.

  • The node-gyp npm package has been updated to version 3.7.0, and the node-pre-gyp npm package has been updated to version 0.10.3.

  • Scripts run via meteor npm ... can now use the meteor command more safely, since the PATH environment variable will now be set so that meteor always refers to the same meteor used to run meteor npm. PR #9941

  • Minimongo's behavior for sorting fields containing an array is now compatible with the behavior of Mongo 3.6+. Note that this means it is now incompatible with the behavior of earlier MongoDB versions. PR #10214

  • Meteor's self-test has been updated to use "headless" Chrome rather than PhantomJS for browser tests. PhantomJS can still be forced by passing the --phantom flag to the meteor self-test command. PR #9814

  • Importing a directory containing an index.* file now works for non-.js file extensions. As before, the list of possible extensions is defined by which compiler plugins you have enabled. PR #10027

  • Any client (modern or legacy) may now request any static JS or CSS web.browser or web.browser.legacy resource, even if it was built for a different architecture, which greatly simplifies CDN setup if your CDN does not forward the User-Agent header to the origin. Issue #9953 PR #9965

  • Cross-origin dynamic import() requests will now succeed in more cases. PR #9954

  • Dynamic CSS modules (which are compiled to JS and handled like any other JS module) will now be properly minified in production and source mapped in development. PR #9998

  • While CSS is only minified in production, CSS files must be merged together into a single stylesheet in both development and production. This merging is cached by standard-minifier-css so that it does not happen on every rebuild in development, but not all CSS minifier packages use the same caching techniques. Thanks to 1ed095c36d, this caching is now performed within the Meteor build tool, so it works the same way for all CSS minifier packages, which may eliminate a few seconds of rebuild time for projects with lots of CSS.

  • The meteor-babel npm package used by babel-compiler has been updated to version 7.1.0. Note: This change requires also updating the @babel/runtime npm package to version 7.0.0-beta.56 or later:

    meteor npm install @babel/runtime@latest

    meteor-babel issue #22

  • The @babel/preset-env and @babel/preset-react presets will be ignored by Meteor if included in a .babelrc file, since Meteor already provides equivalent/superior functionality without them. However, you should feel free to leave these plugins in your .babelrc file if they are needed by external tools.

  • The install npm package used by modules-runtime has been updated to version 0.12.0.

  • The reify npm package has been updated to version 0.17.3, which introduces the module.link(id, {...}) runtime method as a replacement for module.watch(require(id), {...}). Note: in future versions of reify and Meteor, the module.watch runtime API will be removed, but for now it still exists (and is used to implement module.link), so that existing code will continue to work without recompilation.

  • The uglify-es npm package used by minifier-js has been replaced with terser@3.9.2, a fork of uglify-es that appears to be (more actively) maintained. Issue #10042

  • Mongo has been updated to version 4.0.2 and the mongodb npm package used by npm-mongo has been updated to version 3.1.6. PR #10058 Feature Request #269

  • When a Meteor application uses a compiler plugin to process files with a particular file extension (other than .js or .json), those file extensions should be automatically appended to imports that do not resolve as written. However, this behavior was not previously enabled for modules inside node_modules. Thanks to 8b04c25390, the same file extensions that are applied to modules outside the node_modules directory will now be applied to those within it, though .js and .json will always be tried first.

  • As foreshadowed in this talk about Meteor 1.7's modern/legacy bundling system (slides), Meteor now provides an isomorphic implementation of the WHATWG fetch() API, which can be installed by running

    meteor add fetch

    This package is a great demonstration of the modern/legacy bundling system, since it has very different implementations in modern browsers, legacy browsers, and Node. PR #10029

  • The bundle-visualizer package has received a number of UI improvements thanks to work by @jamesmillerburgess in PR #10025. Feature #310

  • Sub-resource integrity hashes (sha512) can now be enabled for static CSS and JS assets by calling WebAppInternals.enableSubresourceIntegrity(). PR #9933 PR #10050

  • The environment variable METEOR_PROFILE=milliseconds now works for the build portion of the meteor build and meteor deploy commands. Feature #239

  • Babel compiler plugins will now receive a caller option of the following form:

    { name: "meteor", arch }

    where arch is the target architecture, e.g. os.*, web.browser, web.cordova, or web.browser.legacy. PR #10211

  • The npm package @babel/runtime, which is depended on by most Meteor apps, introduced a breaking change in version 7.0.0-beta.56 with the removal of the @babel/runtime/helpers/builtin directory. While this change has clear benefits in the long term, in the short term it has been disruptive for Meteor 1.7.0.x applications that accidentally updated to the latest version of @babel/runtime. Meteor 1.7.0.4 is a patch release that provides better warnings about this problem, and ensures newly created Meteor applications do not use 7.0.0-beta.56. PR #10134

  • The npm package has been upgraded to version 6.3.0, and our fork of its pacote dependency has been rebased against version 8.1.6. Issue #9940

Breaking changes

  • The aggregate method of raw Mongo collections now returns an AggregationCursor rather than returning the aggregation result directly. To obtain an array of aggregation results, you will need to call the .toArray() method of the cursor:
    // With MongoDB 2.x, callback style:
    rawCollection.aggregate(
      pipeline,
      (error, results) => {...}
    );
    
    // With MongoDB 2.x, wrapAsync style:
    const results = Meteor.wrapAsync(
      rawCollection.aggregate,
      rawCollection
    )(pipeline);
    
    // With MongoDB 3.x, callback style:
    rawCollection.aggregate(
      pipeline,
      (error, aggregationCursor) => {
        ...
        const results = aggregationCursor.toArray();
        ...
      }
    );
    
    // With MongoDB 3.x, wrapAsync style:
    const results = Meteor.wrapAsync(
      rawCollection.aggregate,
      rawCollection
    )(pipeline).toArray();
    Issue #9936

Migration Steps

  • Update @babel/runtime (as well as other Babel-related packages) and meteor-node-stubs to their latest versions:
    meteor npm install @babel/runtime@latest meteor-node-stubs@latest

Changes

  • Reverted an optimization introduced in Meteor 1.7 to stop scanning node_modules for files that might be of interest to compiler plugins, since the intended workarounds (creating symlinks) did not satisfy all existing use cases. We will revisit this optimization in Meteor 1.8. mozfet/meteor-autoform-materialize#43

  • After updating to Meteor 1.7 or 1.7.0.1, you should update the @babel/runtime npm package (as well as other Babel-related packages) to their latest versions, along with the meteor-node-stubs package, by running the following command:

    meteor npm install @babel/runtime@latest meteor-node-stubs@latest

  • More than 80% of internet users worldwide have access to a web browser that natively supports the latest ECMAScript features and keeps itself updated automatically, which means new features become available almost as soon as they ship. In other words, the future we envisioned when we first began compiling code with Babel is finally here, yet most web frameworks and applications still compile a single client-side JavaScript bundle that must function simultaneously in the oldest and the newest browsers the application developer wishes to support.

    That choice is understandable, because the alternative is daunting: not only must you build multiple JavaScript and CSS bundles for different browsers, with different dependency graphs and compilation rules and webpack configurations, but your server must also be able to detect the capabilities of each visiting client, so that it can deliver the appropriate assets at runtime. Testing a matrix of different browsers and application versions gets cumbersome quickly, so it's no surprise that responsible web developers would rather ship a single, well-tested bundle, and forget about taking advantage of modern features until legacy browsers have disappeared completely.

    With Meteor 1.7, this awkward balancing act is no longer necessary, because Meteor now automatically builds two sets of client-side assets, one tailored to the capabilities of modern browsers, and the other designed to work in all supported browsers, thus keeping legacy browsers working exactly as they did before. Best of all, the entire Meteor community relies on the same system, so any bugs or differences in behavior can be identified and fixed quickly.

    In this system, a "modern" browser can be loosely defined as one with full native support for async functions and await expressions, which includes more than 80% of the world market, and 85% of the US market (source). This standard may seem extremely strict, since async/await was just finalized in ECMAScript 2017, but the statistics clearly justify it. As another example, any modern browser can handle native class syntax, though newer syntax like class fields may still need to be compiled for now, whereas a legacy browser will need compilation for both advanced and basic class syntax. And of course you can safely assume that any modern browser has a native Promise implementation, because async functions must return Promises. The list goes on and on.

    This boundary between modern and legacy browsers is designed to be tuned over time, not only by the Meteor framework itself but also by each individual Meteor application. For example, here's how the minimum versions for native ECMAScript class support might be expressed:

    import { setMinimumBrowserVersions } from "meteor/modern-browsers";
    
    setMinimumBrowserVersions({
      chrome: 49,
      firefox: 45,
      edge: 12,
      ie: Infinity, // Sorry, IE11.
      mobile_safari: [9, 2], // 9.2.0+
      opera: 36,
      safari: 9,
      electron: 1,
    }, "classes");

    The minimum modern version for each browser is simply the maximum of all versions passed to setMinimumBrowserVersions for that browser. The Meteor development server decides which assets to deliver to each client based on the User-Agent string of the HTTP request. In production, different bundles are named with unique hashes, which prevents cache collisions, though Meteor also sets the Vary: User-Agent HTTP response header to let well-behaved clients know they should cache modern and legacy resources separately.

    For the most part, the modern/legacy system will transparently determine how your code is compiled, bundled, and delivered—and yes, it works with every existing part of Meteor, including dynamic import() and even the old appcache package. However, if you're writing dynamic code that depends on modern features, you can use the boolean Meteor.isModern flag to detect the status of the current environment (Node 8 is modern, too, of course). If you're writing a Meteor package, you can call api.addFiles(files, "legacy") in your package.js configuration file to add extra files to the legacy bundle, or api.addFiles(files, "client") to add files to all client bundles, or api.addFiles(files, "web.browser") to add files only to the modern bundle, and the same rules apply to api.mainModule. Just be sure to call setMinimumBrowserVersions (in server startup code) to enforce your assumptions about ECMAScript feature support.

    We think this modern/legacy system is one of the most powerful features we've added since we first introduced the ecmascript package in Meteor 1.2, and we look forward to other frameworks attempting to catch up.

    PR #9439

  • Although Meteor does not recompile packages installed in node_modules by default, compilation of specific npm packages (for example, to support older browsers that the package author neglected) can now be enabled in one of two ways:

    • Clone the package repository into your application's imports directory, make any modifications necessary, then use npm install to link the-package into node_modules:

      meteor npm install imports/the-package

      Meteor will compile the contents of the package exposed via imports/the-package, and this compiled code will be used when you import the-package in any of the usual ways:

      import stuff from "the-package"
      require("the-package") === require("/imports/the-package")
      import("the-package").then(...)

      This reuse of compiled code is the critical new feature that was added in Meteor 1.7.

    • Install the package normally with meteor npm install the-package, then create a symbolic link to the installed package elsewhere in your application, outside of node_modules:

      meteor npm install the-package
      cd imports
      ln -s ../node_modules/the-package .

      Again, Meteor will compile the contents of the package because they are exposed outside of node_modules, and the compiled code will be used whenever the-package is imported from node_modules.

      Note: this technique also works if you create symbolic links to individual files, rather than linking the entire package directory.

    In both cases, Meteor will compile the exposed code as if it was part of your application, using whatever compiler plugins you have installed. You can influence this compilation using .babelrc files or any other techniques you would normally use to configure compilation of application code. PR #9771 Feature #6

    Note: since compilation of npm packages can now be enabled using the techniques described above, Meteor will no longer automatically scan node_modules directories for modules that can be compiled by compiler plugins. If you have been using that functionality to import compiled-to-JS modules from node_modules, you should start using the symlinking strategy instead. Follow-up note: this optimization was reverted in Meteor 1.7.0.1 (see above).

  • Node has been updated to version 8.11.2, officially fixing a cause of frequent segmentation faults in Meteor applications that was introduced in Node 8.10.0. Meteor 1.6.1.1 shipped with a custom build of Node that patched this problem, but that approach was never intended to be permanent.

  • The npm package has been upgraded to version 5.10.0, and our fork of its pacote dependency has been rebased against version 7.6.1.

  • Applications may now specify client and server entry point modules in a newly-supported "meteor" section of package.json:

    "meteor": {
      "mainModule": {
        "client": "client/main.js",
        "server": "server/main.js"
      }
    }

    When specified, these entry points override Meteor's default module loading semantics, rendering imports directories unnecessary. If mainModule is left unspecified for either client or server, the default rules will apply for that architecture, as before. To disable eager loading of modules on a given architecture, simply provide a mainModule value of false:

    "meteor": {
      "mainModule": {
        "client": false,
        "server": "server/main.js"
      }
    }

    Feature #135 PR #9690

  • In addition to meteor.mainModule, the "meteor" section of package.json may also specify meteor.testModule to control which test modules are loaded by meteor test or meteor test --full-app:

    "meteor": {
      "mainModule": {...},
      "testModule": "tests.js"
    }

    If your client and server test files are different, you can expand the testModule configuration using the same syntax as mainModule:

    "meteor": {
      "testModule": {
        "client": "client/tests.js",
        "server": "server/tests.js"
      }
    }

    The same test module will be loaded whether or not you use the --full-app option. Any tests that need to detect --full-app should check Meteor.isAppTest. The module(s) specified by meteor.testModule can import other test modules at runtime, so you can still distribute test files across your codebase; just make sure you import the ones you want to run. PR #9714

  • The meteor create command now supports a --minimal option, which creates an app with as few Meteor packages as possible, in order to minimize client bundle size while still demonstrating advanced features such as server-side rendering. This starter application is a solid foundation for any application that doesn't need Mongo or DDP.

  • The meteor-babel npm package has been updated to version 7.0.0-beta.49-1. Note: while Babel has recently implemented support for a new kind of babel.config.js configuration file (see this PR), and future versions of Meteor will no doubt embrace this functionality, Meteor 1.7 supports only .babelrc files as a means of customizing the default Babel configuration provided by Meteor. In other words, if your project contains a babel.config.js file, it will be ignored by Meteor 1.7.

  • The reify npm package has been updated to version 0.16.2.

  • The meteor-node-stubs package, which provides stub implementations for any Node built-in modules used by the client (such as path and http), has a new minor version (0.4.1) that may help with Windows installation problems. To install the new version, run

    meteor npm install meteor-node-stubs@latest
  • The optimism npm package has been updated to version 0.6.3.

  • The minifier-js package has been updated to use uglify-es 3.3.9.

  • Individual Meteor self-test's can now be skipped by adjusting their define call to be prefixed by skip. For example, selftest.skip.define('some test', ... will skip running "some test". PR #9579

  • Mongo has been upgraded to version 3.6.4 for 64-bit systems, and 3.2.19 for 32-bit systems. PR #9632

    NOTE: After upgrading an application to use Mongo 3.6.4, it has been observed (#9591) that attempting to run that application with an older version of Meteor (via meteor --release X), that uses an older version of Mongo, can prevent the application from starting. This can be fixed by either running meteor reset, or by repairing the Mongo database. To repair the database, find the mongod binary on your system that lines up with the Meteor release you're jumping back to, and run mongodb --dbpath your-apps-db --repair. For example:

    ~/.meteor/packages/meteor-tool/1.6.0_1/mt-os.osx.x86_64/dev_bundle/mongodb/bin/mongod --dbpath /my-app/.meteor/local/db --repair

  • The underscore package has been removed as a dependency from meteor-base. This opens up the possibility of removing 14.4 kb from production bundles. Since this would be a breaking change for any apps that may have been using _ without having any packages that depend on underscore besides meteor-base, we have added an upgrader that will automatically add underscore to the .meteor/packages file of any project which lists meteor-base, but not underscore. Apps which do not require this package can safely remove it using meteor remove underscore. PR #9596

  • Meteor's promise package has been updated to support Promise.prototype.finally. Issue 9639 PR #9663

  • Assets made available via symlinks in the public and private directories of an application are now copied into Meteor application bundles when using meteor build. This means npm package assets that need to be made available publicly can now be symlinked from their node_modules location, in the public directory, and remain available in production bundles. Issue #7013 PR #9666

  • The facts package has been split into facts-base and facts-ui. The original facts package has been deprecated. PR #9629

  • If the new pseudo tag <meteor-bundled-css /> is used anywhere in the <head /> of an app, it will be replaced by the link to Meteor's bundled CSS. If the new tag isn't used, the bundle will be placed at the top of the <head /> section as before (for backwards compatibility). Feature #24 PR #9657

Breaking changes

  • Meteor's Node Mongo driver is now configured with the ignoreUndefined connection option set to true, to make sure fields with undefined values are not first converted to null, when inserted/updated. undefined values are now removed from all Mongo queries and insert/update documents.

    This is a potentially breaking change if you are upgrading an existing app from an earlier version of Meteor.

    For example:

    // return data pertaining to the current user
    db.privateUserData.find({
        userId: currentUser._id // undefined
    });

    Assuming there are no documents in the privateUserData collection with userId: null, in Meteor versions prior to 1.6.1 this query will return zero documents. From Meteor 1.6.1 onwards, this query will now return every document in the collection. It is highly recommend you review all your existing queries to ensure that any potential usage of undefined in query objects won't lead to problems.

  • Node has been updated to version 8.9.4.

  • The meteor-babel npm package (along with its Babel-related dependencies) has been updated to version 7.0.0-beta.38, a major update from Babel 6. Thanks to the strong abstraction of the meteor-babel package, the most noticeable consequence of the Babel 7 upgrade is that the babel-runtime npm package has been replaced by @babel/runtime, which can be installed by running

    in your application directory. There's a good chance that the old babel-runtime package can be removed from your package.json dependencies, though there's no harm in leaving it there. Please see this blog post for general information about updating to Babel 7 (note especially any changes to plugins you've been using in any .babelrc files). PR #9440

  • Because babel-compiler@7.0.0 is a major version bump for a core package, any package that explicitly depends on babel-compiler with api.use or api.imply will need to be updated and republished in order to remain compatible with Meteor 1.6.1. One notable example is the practicalmeteor:mocha package. If you have been using this test-driver package, we strongly recommend switching to meteortesting:mocha instead. If you are the author of a package that depends on babel-compiler, we recommend publishing your updated version using a new major or minor version, so that you can continue releasing patch updates compatible with older versions of Meteor, if necessary.

  • Meteor's Node Mongo driver is now configured with the ignoreUndefined connection option set to true, to make sure fields with undefined values are not first converted to null, when inserted/updated. undefined values are now removed from all Mongo queries and insert/update documents. Issue #6051 PR #9444

  • The server-render package now supports passing a Stream object to ServerSink methods that previously expected a string, which enables streaming server-side rendering with React 16:

  • The bundled version of MongoDB used by meteor run in development on 64-bit architectures has been updated to 3.4.10. 32-bit architectures will continue to use MongoDB 3.2.x versions since MongoDB is no longer producing 32-bit versions of MongoDB for newer release tracks. PR #9396

  • Meteor's internal minifier-css package has been updated to use postcss for CSS parsing and minifying, instead of the abandoned css-parse and css-stringify packages. Changes made to the CssTools API exposed by the minifier-css package are mostly backwards compatible (the standard-minifier-css package that uses it didn't have to change for example), but now that we're using postcss the AST accepted and returned from certain functions is different. This could impact developers who are tying into Meteor's internal minifier-css package directly. The AST based function changes are:

    • CssTools.parseCss now returns a PostCSS Root object.
    • CssTools.stringifyCss expects a PostCSS Root object as its first parameter.
    • CssTools.mergeCssAsts expects an array of PostCSS Root objects as its first parameter.
    • CssTools.rewriteCssUrls expects a PostCSS Root object as its first parameter.

  • The _ variable will once again remain bound to underscore (if installed) in meteor shell, fixing a regression introduced by Node 8. PR #9406

  • Dynamically import()ed modules will now be fetched from the application server using an HTTP POST request, rather than a WebSocket message. This strategy has all the benefits of the previous strategy, except that it does not require establishing a WebSocket connection before fetching dynamic modules, in exchange for slightly higher latency per request. PR #9384

  • To reduce the total number of HTTP requests for dynamic modules, rapid sequences of import() calls within the same tick of the event loop will now be automatically batched into a single HTTP request. In other words, the following code will result in only one HTTP request:

    const [
      React,
      ReactDOM
    ] = await Promise.all([
      import("react"),
      import("react-dom")
    ]);
  • Thanks to a feature request and pull request from @CaptainN, all available dynamic modules will be automatically prefetched after page load and permanently cached in IndexedDB when the appcache package is in use, ensuring that dynamic import() will work for offline apps. Although the HTML5 Application Cache was deliberately not used for this prefetching, the new behavior matches the spirit/intention of the appcache package. Feature Request #236 PR #9482 PR #9434

  • The es5-shim library is no longer included in the initial JavaScript bundle, but is instead injected using a <script> tag in older browsers that may be missing full support for ECMAScript 5. For the vast majority of modern browsers that do not need es5-shim, this change will reduce the bundle size by about 10KB (minified, pre-gzip). For testing purposes, the <script> tag injection can be triggered in any browser by appending ?force_es5_shim=1 to the application URL. PR #9360

  • The Tinytest.addAsync API now accepts test functions that return Promise objects, making the onComplete callback unnecessary:

    Tinytest.addAsync("some async stuff", async function (test) {
      test.equal(shouldReturnFoo(), "foo");
      const bar = await shouldReturnBarAsync();
      test.equal(bar, "bar");

  • Line number comments are no longer added to bundled JavaScript files on the client or the server. Several years ago, before all major browsers supported source maps, we felt it was important to provide line number information in generated files using end-of-line comments like

    some.code(1234); // 123
    more.code(5, 6); // 124

    Adding all these comments was always slower than leaving the code unmodified, but recently the comments have begun interacting badly with certain newer ECMAScript syntax, such as multi-line template strings. Since source maps are well supported in most browsers that developers are likely to be using for development, and the line number comments are now causing substantive problems beyond the performance cost, we concluded it was time to stop using them. PR #9323 Issue #9160

  • Since Meteor 1.3, Meteor has supported string-valued "browser" fields in package.json files, to enable alternate entry points for packages in client JavaScript bundles. In Meteor 1.6.1, we are expanding support to include object-valued "browser" fields, according to this unofficial and woefully incomplete (but widely-implemented) "spec document." We are only supporting the "relative style" of browser replacements, however, and not the "package style" (as detailed in this comment), because supporting the package style would have imposed an unacceptable runtime cost on all imports (not just those overridden by a "browser" field).

v1.6.0.1, 2017-12-08

  • Node has been upgraded to version 8.9.3, an important security release.

  • The npm package has been upgraded to version 5.5.1, which supports several new features, including two-factor authentication, as described in the release notes.

v1.6, 2017-10-30

  • Important note for package maintainers:

    With the jump to Node 8, some packages published using Meteor 1.6 may no longer be compatible with older Meteor versions. In order to maintain compatibility with Meteor 1.5 apps when publishing your package, you can specify a release version with the meteor publish command:

    meteor --release 1.5.3 publish
    

    If you're interested in taking advantage of Meteor 1.6 while still supporting older Meteor versions, you can consider publishing for Meteor 1.6 from a new branch, with your package's minor or major version bumped. You can then continue to publish for Meteor 1.5 from the original branch. Note that the 1.6 branch version bump is important so that you can continue publishing patch updates for Meteor 1.5 from the original branch.

    Issue #9308

  • Node.js has been upgraded to version 8.8.1, which will be entering long-term support (LTS) coverage on 31 October 2017, lasting through December 2019 (full schedule). This is a major upgrade from the previous version of Node.js used by Meteor, 4.8.4.

  • The npm npm package has been upgraded to version 5.4.2, a major upgrade from 4.6.1. While this update should be backwards-compatible for existing Meteor apps and packages, if you are the maintainer of any Meteor packages, pay close attention to your npm-shrinkwrap.json files when first using this version of npm. For normal Meteor application development, this upgrade primarily affects the version of npm used by meteor npm ... commands. A functional installation of git may be required to support GitHub repository and/or tarball URLs. Troubleshooting. PR #8835

  • In addition to meteor node and meteor npm, which are convenient shorthands for node and npm, meteor npx <command> can be used to execute commands from a local node_modules/.bin directory or from the npm cache. Any packages necessary to run the command will be automatically downloaded. Read about it, or just try some commands:

    meteor npx cowsay mooooo
    meteor npx uuid
    meteor npx nyancat
    meteor npx yarn
  • The meteor debug command has been superseded by the more flexible --inspect and --inspect-brk command-line flags, which work for any run, test, or test-packages command.

    The syntax of these flags is the same as the equivalent Node.js flags, with two notable differences:

    • The flags affect the server process spawned by the build process, rather than affecting the build process itself.

    • The --inspect-brk flag causes the server process to pause just after server code has loaded but before it begins to execute, giving the developer a chance to set breakpoints in server code.

    Feature Request #194

  • On Windows, Meteor can now be installed or reinstalled from scratch using the command choco install meteor, using the Chocolatey package manager. This method of installation replaces the old InstallMeteor.exe installer, which had a number of shortcomings, and will no longer be supported.

  • Fresh installs of Meteor 1.6 on 64-bit Windows machines will now use native 64-bit Node.js binaries, rather than a 32-bit version of Node.js. In addition to being faster, native 64-bit support will enable Windows developers to debug asynchronous stack traces more easily in the new Node.js inspector, which is only fully supported by native 64-bit architectures. Note that merely running meteor update from a 32-bit version of Meteor will still install a 32-bit version of Meteor 1.6, so you should use choco install meteor to get a fresh 64-bit version.

  • To support developers running on a 32-bit OS, Meteor now supports both 32- and 64-bit versions of Mongo. Mongo 3.2 is the last 32-bit version available from Mongo. Meteor running on a 32-bit OS will use a 32-bit version of Mongo 3.2 and 64-bit platforms will receive newer Mongo versions in future releases. PR #9173

  • After several reliability improvements, native file watching has been un-disabled on Windows. Though native file change notifications will probably never work with network or shared virtual file systems (e.g., NTFS or Vagrant-mounted disks), Meteor uses an efficient prioritized polling system as a fallback for those file systems.

  • Various optimizations have reduced the on-disk size of the meteor-tool package from 545MB (1.5.2.2) to 219MB.

  • The meteor-babel package has been upgraded to version 0.24.6, to take better advantage of native language features in Node 8.

  • The reify npm package has been upgraded to version 0.12.3.

  • The meteor-promise package has been upgraded to version 0.8.6, to enable better handling of UnhandledPromiseRejectionWarnings.

  • The node-gyp npm package has been upgraded to version 3.6.2.

  • The node-pre-gyp npm package has been updated to version 0.6.36.

  • The fibers npm package has been upgraded to version 2.0.0.

  • The pathwatcher npm package has been upgraded to version 7.1.0.

  • The http-proxy npm package has been upgraded to version 1.16.2.

  • The semver npm package has been upgraded to version 5.4.1.

  • When running Meteor tool tests (i.e. ./meteor self-test) during the course of developing Meteor itself, it is no longer necessary to ./meteor npm install -g phantomjs-prebuilt browserstack-webdriver. These will now be installed automatically upon their use.

  • You can now run meteor test --driver-package user:package without first running meteor add user:package.

  • Node has been updated to version 4.8.6. This release officially includes our fix of a faulty backport of garbage collection-related logic in V8 and ends Meteor's use of a custom Node with that patch. In addition, it includes small OpenSSL updates as announced on the Node blog: https://nodejs.org/en/blog/release/v4.8.6/. Issue #8648

  • Node has been upgraded to version 4.8.5, a recommended security release: https://nodejs.org/en/blog/release/v4.8.5/. While it was expected that Node 4.8.5 would also include our fix of a faulty backport of garbage collection-related logic in V8, the timing of this security release has caused that to be delayed until 4.8.6. Therefore, this Node still includes our patch for this issue. Issue #8648

  • Various backports from Meteor 1.6, as detailed in the PR for Meteor 1.5.3. Briefly, these involve fixes for:

    • Child imports of dynamically imported modules within packages. #9182
    • Unresolved circular dependencies. #9176
    • Windows temporary directory handling.

v1.5.2.2, 2017-10-02

  • Fixes a regression in 1.5.2.1 which resulted in the macOS firewall repeatedly asking to "accept incoming network connections". While the node binary in 1.5.2.1 was functionally the same as 1.5.2, it had been recompiled on our build farm (which re-compiles all architectures at the same time) to ensure compatibility with older (but still supported) Linux distributions. Unfortunately, macOS took issue with the binary having a different 'signature' (but same 'identifier') as one it had already seen, and refused to permanently "allow" it in the firewall. Our macOS node binaries are now signed with a certificate, hopefully preventing this from occurring again. Issue #9139

  • Fixes a regression in accounts-base caused by changes to the (now deprecated) connection.onReconnect function which caused users to be logged out shortly after logging in. Issue #9140 PR #

  • A bug that prevented building some binary npm packages on Windows has been fixed. Issue #9153

v1.5.2.1, 2017-09-26

  • Updating to Meteor 1.5.2.1 will automatically patch a security vulnerability in the allow-deny package, since meteor-tool@1.5.2_1 requires allow-deny@1.0.9 or later. If for any reason you are not ready or able to update to Meteor 1.5.2.1 by running meteor update, please at least run

    meteor update allow-deny

    instead. More details about the security vulnerability can be found on the Meteor forums.

  • The command-line meteor tool no longer invokes node with the --expose-gc flag. Although this flag allowed the build process to be more aggressive about collecting garbage, it was also a source of problems in Meteor 1.5.2 and Node 4.8.4, from increased segmentation faults during (the more frequent) garbage collections to occasional slowness in rebuilding local packages. The flag is likely to return in Meteor 1.6, where it has not exhibited any of the same problems.

  • Meteor now supports .meteorignore files, which cause the build system to ignore certain files and directories using the same pattern syntax as .gitignore files. These files may appear in any directory of your app or package, specifying rules for the directory tree below them. Of course, .meteorignore files are also fully integrated with Meteor's file watching system, so they can be added, removed, or modified during development. Feature request #5

  • DDP's connection.onReconnect = func feature has been deprecated. This functionality was previously supported as a way to set a function to be called as the first step of reconnecting. This approach has proven to be inflexible as only one function can be defined to be called when reconnecting. Meteor's accounts system was already setting an onReconnect callback to be used internally, which means anyone setting their own onReconnect callback was inadvertently overwriting code used internally. Moving forward the DDP.onReconnect(callback) method should be used to register callbacks to call when a connection reconnects. The connection that is reconnecting is passed as the only argument to callback. This is used by the accounts system to re-login on reconnects without interfering with other code that uses connection.onReconnect. Issue #5665 PR #9092

  • The webapp package has been updated to support UNIX domain sockets. If a UNIX_SOCKET_PATH environment variable is set with a valid UNIX socket file path (e.g. UNIX_SOCKET_PATH=/tmp/socktest.sock), Meteor's HTTP server will use that socket file for inter-process communication, instead of TCP. This can be useful in cases like using Nginx to proxy requests back to an internal Meteor application. Leveraging UNIX domain sockets for inter-process communication reduces the sometimes unnecessary overhead required by TCP based communication. Issue #7392 PR #8702

  • The fastclick package (previously included by default in Cordova applications through the mobile-experience package) has been deprecated. This package is no longer maintained and has years of outstanding unresolved issues, some of which are impacting Meteor users. Most modern mobile web browsers have removed the 300ms tap delay that fastclick worked around, as long as the following <head /> meta element is set (which is generally considered a mobile best practice regardless, and which the Meteor boilerplate generator already sets by default for Cordova apps): <meta name="viewport" content="width=device-width"> If anyone is still interested in using fastclick with their application, it can be installed from npm directly (meteor npm install --save fastclick).

  • The meteor-babel package has been upgraded to version 0.23.1.

  • The reify npm package has been upgraded to version 0.12.0, which includes a minor breaking change that correctly skips exports named default in export * from "module" declarations. If you have any wrapper modules that re-export another module's exports using export * from "./wrapped/module", and the wrapped module has a default export that you want to be included, you should now explicitly re-export default using a second declaration:

    export * from "./wrapped/module";
    export { default } "./wrapped/module";

  • The uglify-js npm package has been upgraded to version 3.0.28.

  • Thanks to PRs #8960 and #9018 by @GeoffreyBooth, a coffeescript-compiler package has been extracted from the coffeescript package, similar to how the babel-compiler package is separate from the ecmascript package, so that other packages (such as vue-coffee) can make use of coffeescript-compiler. All coffeescript-related packages have been moved to packages/non-core, so that they can be published independently from Meteor releases.

  • The star.json manifest created within the root of a meteor build bundle will now contain nodeVersion and npmVersion which will specify the exact versions of Node.js and npm (respectively) which the Meteor release was bundled with. The .node_version.txt file will still be written into the root of the bundle, but it may be deprecated in a future version of Meteor. PR #8956

  • A new package called mongo-dev-server has been created and wired into mongo as a dependency. As long as this package is included in a Meteor application (which it is by default since all new Meteor apps have mongo as a dependency), a local development MongoDB server is started alongside the application. This package was created to provide a way to disable the local development Mongo server, when mongo isn't needed (e.g. when using Meteor as a build system only). If an application has no dependency on mongo, the mongo-dev-server package is not added, which means no local development Mongo server is started. Feature Request #31 PR #8853

  • A new core Meteor package called server-render provides generic support for server-side rendering of HTML, as described in the package's README.md. PR #8841

  • To reduce the total number of file descriptors held open by the Meteor build system, native file watchers will now be started only for files that have changed at least once. This new policy means you may have to wait up to 5000ms for changes to be detected when you first edit a file, but thereafter changes will be detected instantaneously. In return for that small initial waiting time, the number of open file descriptors will now be bounded roughly by the number of files you are actively editing, rather than the number of files involved in the build (often thousands), which should help with issues like #8648. If you need to disable the new behavior for any reason, simply set the METEOR_WATCH_PRIORITIZE_CHANGED environment variable to "false", as explained in PR #8866.

  • All observe and observeChanges callbacks are now bound using Meteor.bindEnvironment. The same EnvironmentVariables that were present when observe or observeChanges was called are now available inside the callbacks. PR #8734

  • A subscription's onReady is now fired again during a re-subscription, even if the subscription has the same arguments. Previously, when subscribing to a publication the onReady would have only been called if the arguments were different, creating a confusing difference in functionality. This may be breaking behavior if an app uses the firing of onReady as an assumption that the data was just received from the server. If such functionality is still necessary, consider using observe or observeChanges PR #8754 Issue #1173

  • The minimongo and mongo packages are now compliant with the upsert behavior of MongoDB 2.6 and higher. As a result support for MongoDB 2.4 has been dropped. This mainly changes the effect of the selector on newly inserted documents. PR #8815

  • reactive-dict now supports setting initial data when defining a named ReactiveDict. No longer run migration logic when used on the server, this is to prevent duplicate name error on reloads. Initial data is now properly serialized.

  • accounts-password now uses example.com as a default "from" address instead of meteor.com. This change could break account-related e-mail notifications (forgot password, activation, etc.) for applications which do not properly configure a "from" domain since e-mail providers will often reject mail sent from example.com. Ensure that Accounts.emailTemplates.from is set to a proper domain in all applications. PR #8760

  • The accounts-facebook and facebook-oauth packages have been updated to use the v2.9 of the Facebook Graph API for the Login Dialog since the v2.2 version will be deprecated by Facebook in July. There shouldn't be a problem regardless since Facebook simply rolls over to the next active version (v2.3, in this case) however this should assist in avoiding deprecation warnings and should enable any new functionality which has become available. PR #8858

  • Add DDP._CurrentPublicationInvocation and DDP._CurrentMethodInvocation. DDP._CurrentInvocation remains for backwards-compatibility. This change allows method calls from publications to inherit the connection from the the publication which called the method. PR #8629

    Note: If you're calling methods from publications that are using this.connection to see if the method was called from server code or not. These checks will now be more restrictive because this.connection will now be available when a method is called from a publication.

  • Fix issue with publications temporarily having DDP._CurrentInvocation set on re-run after a user logged in. This is now provided through DDP._CurrentPublicationInvocation at all times inside a publication, as described above. PR #8031 PR #8629

  • Meteor.userId() and Meteor.user() can now be used in both method calls and publications. PR #8629

  • this.onStop callbacks in publications are now run with the publication's context and with its EnvironmentVariables bound. PR #8629

  • The minifier-js package will now replace process.env.NODE_ENV with its string value (or "development" if unspecified).

  • The meteor-babel npm package has been upgraded to version 0.22.0.

  • The reify npm package has been upgraded to version 0.11.24.

  • The uglify-js npm package has been upgraded to version 3.0.18.

  • Illegal characters in paths written in build output directories will now be replaced with _s rather than removed, so that file and directory names consisting of only illegal characters do not become empty strings. PR #8765.

  • Additional "extra" packages (packages that aren't saved in .meteor/packages) can be included temporarily using the --extra-packages option. For example: meteor run --extra-packages bundle-visualizer. Both meteor test and meteor test-packages also support the --extra-packages option and commas separate multiple package names. PR #8769

    Note: Packages specified using the --extra-packages option override version constraints from .meteor/packages.

  • The coffeescript package has been updated to use CoffeeScript version 1.12.6. PR #8777

v1.5, 2017-05-30

  • The meteor-base package implies a new dynamic-import package, which provides runtime support for the proposed ECMAScript dynamic import(...) syntax, enabling asynchronous module fetching or "code splitting." If your app does not use the meteor-base package, you can use the package by simply running meteor add dynamic-import. See this blog post and PR #8327 for more information about how dynamic import(...) works in Meteor, and how to use it in your applications.

  • The ecmascript-runtime package, which provides polyfills for various new ECMAScript runtime APIs and language features, has been split into ecmascript-runtime-client and ecmascript-runtime-server, to reflect the different needs of browsers versus Node 4. The client runtime now relies on the core-js library found in the node_modules directory of the application, rather than a private duplicate installed via Npm.depends. This is unlikely to be a disruptive change for most developers, since the babel-runtime npm package is expected to be installed, and core-js is a dependency of babel-runtime, so node_modules/core-js should already be present. If that's not the case, just run meteor npm install --save core-js to install it.

  • The npm npm package has been upgraded to version 4.6.1.

  • The meteor-babel npm package has been upgraded to version 0.21.4, enabling the latest Reify compiler and the transform-class-properties plugin, among other improvements.

  • The reify npm package has been upgraded to version 0.11.21, fixing issue #8595 and improving compilation and runtime performance.

Note: With this version of Reify, import declarations are compiled to module.watch(require(id), ...) instead of module.importSync(id, ...) or the older module.import(id, ...). The behavior of the compiled code should be the same as before, but the details seemed different enough to warrant a note.

  • The install npm package has been upgraded to version 0.10.1.

  • The meteor-promise npm package has been upgraded to version 0.8.4.

  • The uglify-js npm package has been upgraded to version 3.0.13, fixing #8704.

  • If you're using the standard-minifier-js Meteor package, as most Meteor developers do, it will now produce a detailed analysis of package and module sizes within your production .js bundle whenever you run meteor build or meteor run --production. These data are served by the application web server at the same URL as the minified .js bundle, except with a .stats.json file extension instead of .js. If you're using a different minifier plugin, and would like to support similar functionality, refer to these commits for inspiration.

  • To visualize the bundle size data produced by standard-minifier-js, run meteor add bundle-visualizer and then start your development server in production mode with meteor run --production. Be sure to remove the bundle-visualizer package before actually deploying your app, or the visualization will be displayed to your users.

  • If you've been developing an app with multiple versions of Meteor, or testing with beta versions, and you haven't recently run meteor reset, your .meteor/local/bundler-cache directory may have become quite large. This is just a friendly reminder that this directory is perfectly safe to delete, and Meteor will repopulate it with only the most recent cached bundles.

  • Apps created with meteor create --bare now use the static-html package for processing .html files instead of blaze-html-templates, to avoid large unnecessary dependencies like the jquery package.

  • Babel plugins now receive file paths without leading / characters, which should prevent confusion about whether the path should be treated as absolute. PR #8610

  • It is now possible to override the Cordova iOS and/or Android compatibility version by setting the METEOR_CORDOVA_COMPAT_VERSION_IOS and/or METEOR_CORDOVA_COMPAT_VERSION_ANDROID environment variables. PR #8581

  • Modules in node_modules directories will no longer automatically have access to the Buffer polyfill on the client, since that polyfill contributed more than 22KB of minified JavaScript to the client bundle, and was rarely used. If you really need the Buffer API on the client, you should now obtain it explicitly with require("buffer").Buffer. Issue #8645.

  • Packages in node_modules directories are now considered non-portable (and thus may be automatically rebuilt for the current architecture), if their package.json files contain any of the following install hooks: install, preinstall, or postinstall. Previously, a package was considered non-portable only if it contained any .node binary modules. Issue #8225

v1.4.4.6, 2018-04-02

  • Node has been upgraded to version 4.9.0, an important security release. The Node v4.x release line will exit the Node.js Foundation's long-term support (LTS) status on April 30, 2018. We strongly advise updating to a version of Meteor using a newer version of Node which is still under LTS status, such as Meteor 1.6.x which uses Node 8.x.

  • The npm package has been upgraded to version 4.6.1.

v1.4.4.4, 2017-09-26

  • Updating to Meteor 1.4.4.4 will automatically patch a security vulnerability in the allow-deny package, since meteor-tool@1.4.4_4 requires allow-deny@1.0.9 or later. If for any reason you are not ready or able to update to Meteor 1.4.4.4 by running meteor update, please at least run
    meteor update allow-deny

  • Update node-inspector npm to 1.1.1, fixing a problem encountered when trying to press "Enter" in the inspector console. Issue #8469

  • The email package has had its mailcomposer npm package swapped with a Node 4 fork of nodemailer due to its ability to support connection pooling in a similar fashion as the original mailcomposer. Issue #8591 PR #8605

    Note: The MAIL_URL should be configured with a scheme which matches the protocol desired by your e-mail vendor/mail-transport agent. For encrypted connections (typically listening on port 465), this means using smtps://. Unencrypted connections or those secured through a STARTTLS connection upgrade (typically using port 587 and sometimes port 25) should continue to use smtp://. TLS/SSL will be automatically enabled if the mail provider supports it.

  • A new Tracker.inFlush() has been added to provide a global Tracker "flushing" state. PR #8565.

  • The meteor-babel npm package has been upgraded to version 0.20.1, and the reify npm package has been upgraded to version 0.7.4, fixing issue #8595. (This was fixed between full Meteor releases, but is being mentioned here.)

  • The reify npm package has been upgraded to version 0.4.9.

  • Partial npm-shrinkwrap.json files are now disregarded when (re)installing npm dependencies of Meteor packages, fixing #8349. Further discussion of the new npm behavior can be found here.

v1.4.3, 2017-02-13

  • Versions of Meteor core packages are once again constrained by the current Meteor release.

Before Meteor 1.4, the current release dictated the exact version of every installed core package, which meant newer core packages could not be installed without publishing a new Meteor release. In order to support incremental development of core packages, Meteor 1.4 removed all release-based constraints on core package versions (#7084). Now, in Meteor 1.4.3, core package versions must remain patch-compatible with the versions they had when the Meteor release was published. This middle ground restores meaning to Meteor releases, yet still permits patch updates to core packages.

  • The cordova-lib npm package has been updated to 6.4.0, along with cordova-android (6.1.1) and cordova-ios (4.3.0), and various plugins. #8239

  • The coffeescript Meteor package has been moved from packages/coffeescript to packages/non-core/coffeescript, so that it will not be subject to the constraints described above.

  • CoffeeScript source maps should be now be working properly in development. #8298

  • The individual account "service" packages (facebook, google, twitter, github, meteor-developer, meetup and weibo) have been split into:

    • <service>-oauth (which interfaces with the <service> directly) and
    • <service>-config-ui (the Blaze configuration templates for accounts-ui)

    This means you can now use accounts-<service> without needing Blaze.

    If you are using accounts-ui and accounts-<service>, you will probably need to install the <service>-config-ui package if you want to configure it using the Accounts UI.

  • The url and http packages now encode to a less error-prone format which more closely resembles that used by PHP, Ruby, jQuery.param and others. Objects and Arrays can now be encoded, however, if you have previously relied on Arrays passed as params being simply join-ed with commas, you may need to adjust your HTTP.call implementations. #8261 and #8342.

  • The npm npm package is still at version 4.1.2 (as it was when Meteor 1.4.3 was originally published), even though npm was downgraded to 3.10.9 in Meteor 1.4.2.7.

  • The meteor-babel npm package has been upgraded to version 0.14.3, fixing #8021 and #7662.

  • The reify npm package has been upgraded to 0.4.7.

  • Added support for frame-ancestors CSP option in browser-policy. #7970

  • You can now use autoprefixer with stylus files added via packages. #7727

  • Restored #8213 after those changes were reverted in v1.4.2.5.

  • npm dependencies of Meteor packages will now be automatically rebuilt if the npm package's package.json file has "scripts" section containing a preinstall, install, or postinstall command, as well as when the npm package contains any .node files. Discussion here.

  • The meteor create command now runs meteor npm install automatically to install dependencies specified in the default package.json file. #8108

v1.4.2.7, 2017-02-13

  • The npm npm package has been downgraded from version 4.1.2 back to version 3.10.9, reverting the upgrade in Meteor 1.4.2.4.

v1.4.2.6, 2017-02-08

  • Fixed a critical bug that was introduced by the fix for Issue #8136, which caused some npm packages in nested node_modules directories to be omitted from bundles produced by meteor build and meteor deploy.

v1.4.2.5, 2017-02-03

  • Reverted #8213 as the change was deemed too significant for this release.

Note: The decision to revert the above change was made late in the Meteor 1.4.2.4 release process, before it was ever recommended but too late in the process to avoid the additional increment of the version number. See #8311 for additional information. This change will still be released in an upcoming version of Meteor with a more seamless upgrade.

v1.4.2.4, 2017-02-02

  • Node has been upgraded to version 4.7.3.

  • The npm npm package has been upgraded from version 3.10.9 to 4.1.2.

Note: This change was later deemed too substantial for a point release and was reverted in Meteor 1.4.2.7.

  • Fix for Issue #8136.

  • Fix for Issue #8222.

  • Fix for Issue #7849.

  • The version of 7-zip included in the Windows dev bundle has been upgraded from 1602 to 1604 in an attempt to mitigate Issue #7688.

  • The "main" field of package.json modules will no longer be overwritten with the value of the optional "browser" field, now that the install npm package can make sense of the "browser" field at runtime. If you experience module resolution failures on the client after updating Meteor, make sure you've updated the modules-runtime Meteor package to at least version 0.7.8. #8213

v1.4.2.3, 2016-11-17

  • Style improvements for meteor create --full. #8045

Note: Meteor 1.4.2.2 was finalized before #8045 was merged, but those changes were deemed important enough to skip recommending 1.4.2.2 and instead immediately release 1.4.2.3.

v1.4.2.2, 2016-11-15

  • Node has been upgraded to version 4.6.2.

  • meteor create now has a new --full option, which generates an larger app, demonstrating development techniques highlighted in the Meteor Guide

    Issue #6974 PR #7807

  • Minimongo now supports $min, $max and partially supports $currentDate.

    Issue #7857 PR #7858

  • Fix for Issue #5676 PR #7968

  • It is now possible for packages to specify a lazy main module:

    Package.onUse(function (api) {
      api.mainModule("client.js", "client", { lazy: true });
    });

    This means the client.js module will not be evaluated during app startup unless/until another module imports it, and will not even be included in the client bundle if no importing code is found. Note 1: packages with lazy main modules cannot use api.export to export global symbols to other packages/apps. Note 2: packages with lazy main modules should be restricted to Meteor 1.4.2.2 or later via api.versionsFrom("1.4.2.2"), since older versions of Meteor cannot import lazy main modules using import "meteor/<package name>" but must explicitly name the module: import "meteor/<package name>/client.js".

v1.4.2.1, 2016-11-08

  • Installing the babel-runtime npm package in your application node_modules directory is now required for most Babel-transformed code to work, as the Meteor babel-runtime package no longer attempts to provide custom implementations of Babel helper functions. To install the babel-runtime package, simply run the command

    meteor npm install --save babel-runtime

    in any Meteor application directory. The Meteor babel-runtime package version has been bumped to 1.0.0 to reflect this major change. #7995

  • File system operations performed by the command-line tool no longer use fibers unless the METEOR_DISABLE_FS_FIBERS environment variable is explicitly set to a falsy value. For larger apps, this change results in significant build performance improvements due to the creation of fewer fibers and the avoidance of unnecessary asyncronous delays. https://github.com/meteor/meteor/pull/7975/commits/ca4baed90ae0675e55c93976411d4ed91f12dd63

  • Running Meteor as root is still discouraged, and results in a fatal error by default, but the --allow-superuser flag now works as claimed. #7959

  • The dev_bundle\python\python.exe executable has been restored to the Windows dev bundle, which may help with meteor npm rebuild commands. #7960

  • Changes within linked npm packages now trigger a partial rebuild, whereas previously (in 1.4.2) they were ignored. #7978

  • Miscellaneous fixed bugs: #2876 #7154 #7956 #7974 #7999 #8005 #8007

v1.4.2, 2016-10-25

  • This release implements a number of rebuild performance optimizations. As you edit files in development, the server should restart and rebuild much more quickly, especially if you have many node_modules files. See https://github.com/meteor/meteor/pull/7668 for more details.

Note: the METEOR_PROFILE environment variable now provides data for server startup time as well as build time, which should make it easier to tell which of your packages are responsible for slow startup times. Please include the output of METEOR_PROFILE=10 meteor run with any GitHub issue about rebuild performance.

  • npm has been upgraded to version 3.10.9.

  • The cordova-lib npm package has been updated to 6.3.1, along with cordova-android (5.2.2) and cordova-ios (4.2.1), and various plugins.

  • The node-pre-gyp npm package has been updated to 0.6.30.

  • The lru-cache npm package has been updated to 4.0.1.

  • The meteor-promise npm package has been updated to 0.8.0 for better asynchronous stack traces.

  • The meteor tool is now prevented from running as root as this is not recommended and can cause issues with permissions. In some environments, (e.g. Docker), it may still be desired to run as root and this can be permitted by passing --unsafe-perm to the meteor command. #7821

  • Blaze-related packages have been extracted to meteor/blaze, and the main meteor/meteor repository now refers to them via git submodules (see #7633). When running meteor from a checkout, you must now update these submodules by running

    git submodule update --init --recursive

    in the root directory of your meteor checkout.

  • Accounts.forgotPassword and .verifyEmail no longer throw errors if callback is provided. Issue #5664 Origin PR #5681 Merged PR

  • The default content security policy (CSP) for Cordova now includes ws: and wss: WebSocket protocols. #7774

  • meteor npm commands are now configured to use dev_bundle/.npm as the npm cache directory by default, which should make npm commands less sensitive to non-reproducible factors in the external environment. https://github.com/meteor/meteor/pull/7668/commits/3313180a6ff33ee63602f7592a9506012029e919

  • JavaScript module bundles on the server no longer include transitive node_modules dependencies, since those dependencies can be evaluated directly by Node. This optimization should improve server rebuild times for apps and packages with large node_modules directories. https://github.com/meteor/meteor/pull/7668/commits/03c5346873849151cecc3e00606c6e5aa13b3bbc

  • The standard-minifier-css package now does basic caching for the expensive mergeCss function. https://github.com/meteor/meteor/pull/7668/commits/bfa67337dda1e90610830611fd99dcb1bd44846a

  • The coffeescript package now natively supports import and export declarations. #7818

  • Due to changes in how Cordova generates version numbers for iOS and Android apps, you may experience issues with apps updating on user devices. To avoid this, consider managing the buildNumber manually using App.info('buildNumber', 'XXX'); in mobile-config.js. There are additional considerations if you have been setting android:versionCode or ios-CFBundleVersion. See #7205 and #6978 for more information.

v1.4.1.3, 2016-10-21

  • Node has been updated to version 4.6.1: https://nodejs.org/en/blog/release/v4.6.1/

  • The mongodb npm package used by the npm-mongo Meteor package has been updated to version 2.2.11. #7780

  • The fibers npm package has been upgraded to version 1.0.15.

  • Running Meteor with a different --port will now automatically reconfigure the Mongo replica set when using the WiredTiger storage engine, instead of failing to start Mongo. #7840.

  • When the Meteor development server shuts down, it now attempts to kill the mongod process it spawned, in addition to killing any running mongod processes when the server first starts up. https://github.com/meteor/meteor/pull/7668/commits/295d3d5678228f06ee0ab6c0d60139849a0ea192

  • The meteor <command> ... syntax will now work for any command installed in dev_bundle/bin, except for Meteor's own commands.

  • Incomplete package downloads will now fail (and be retried several times) instead of silently succeeding, which was the cause of the dreaded Error: ENOENT: no such file or directory, open... os.json error. #7806

v1.4.1.2, 2016-10-04

v1.4.1.1, 2016-08-24

  • Update the version of our Node MongoDB driver to 2.2.8 to fix a bug in reconnection logic, leading to some update and remove commands being treated as inserts. #7594

v1.4.1, 2016-08-18

  • Node has been upgraded to 4.5.0.

  • npm has been upgraded to 3.10.6.

  • The meteor publish-for-arch command is no longer necessary when publishing Meteor packages with binary npm dependencies. Instead, binary dependencies will be rebuilt automatically on the installation side. Meteor package authors are not responsible for failures due to compiler toolchain misconfiguration, and any compilation problems with the underlying npm packages should be taken up with the authors of those packages. That said, if a Meteor package author really needs or wants to continue using meteor publish-for-arch, she should publish her package using an older release: e.g. meteor --release 1.4 publish. #7608

  • The .meteor-last-rebuild-version.json files that determine if a binary npm package needs to be rebuilt now include more information from the process object, namely process.{platform,arch,versions} instead of just process.versions. Note also that the comparison of versions now ignores differences in patch versions, to avoid needless rebuilds.

  • The npm-bcrypt package now uses a pure-JavaScript implementation by default, but will prefer the native bcrypt implementation if it is installed in the application's node_modules directory. In other words, run meteor install --save bcrypt in your application if you need or want to use the native implementation of bcrypt. #7595

  • After Meteor packages are downloaded from Atmosphere, they will now be extracted using native tar or 7z.exe on Windows, instead of the https://www.npmjs.com/package/tar library, for a significant performance improvement. #7457

  • The npm tar package has been upgraded to 2.2.1, though it is now only used as a fallback after native tar and/or 7z.exe.

  • The progress indicator now distinguishes between downloading, extracting, and loading newly-installed Meteor packages, instead of lumping all of that work into a "downloading" status message.

  • Background Meteor updates will no longer modify the ~/.meteor/meteor symbolic link (or AppData\Local\.meteor\meteor.bat on Windows). Instead, developers must explicitly type meteor update to begin using a new version of the meteor script.

  • Password Reset tokens now expire (after 3 days by default -- can be modified via Accounts.config({ passwordResetTokenExpirationInDays: ...}). PR #7534

  • The google package now uses the email scope as a mandatory field instead of the profile scope. The profile scope is still added by default if the requestPermissions option is not specified to maintain backward compatibility, but it is now possible to pass an empty array to requestPermissions in order to only request the email scope, which reduces the amount of permissions requested from the user in the Google popup. PR #6975

  • Added Facebook.handleAuthFromAccessToken in the case where you get the FB accessToken in some out-of-band way. PR #7550

  • Accounts.onLogout gets { user, connection } context in a similar fashion to Accounts.onLogin. Issue #7397 PR #7433

  • The node-gyp and node-pre-gyp tools will now be installed in bundle/programs/server/node_modules, to assist with rebuilding binary npm packages when deploying an app to Galaxy or elsewhere. #7571

  • The standard-minifier-{js,css} packages no longer minify .js or .css files on the server. #7572

  • Multi-line input to meteor shell, which was broken by changes to the repl module in Node 4, works again. #7562

  • The implementation of the command-line meteor tool now forbids misbehaving polyfill libraries from overwriting global.Promise. #7569

  • The oauth-encryption package no longer depends on the npm-node-aes-gcm package (or any special npm packages), because the Node 4 crypto library natively supports the aes-128-gcm algorithm. #7548

  • The server-side component of the meteor shell command has been moved into a Meteor package, so that it can be developed independently from the Meteor release process, thanks to version unpinning. #7624

  • The meteor shell command now works when running meteor test.

  • The meteor debug command no longer pauses at the first statement in the Node process, yet still reliably stops at custom breakpoints it encounters later.

  • The meteor-babel package has been upgraded to 0.12.0.

  • The meteor-ecmascript-runtime package has been upgraded to 0.2.9, to support several additional stage 4 proposals.

  • A bug that prevented @-scoped npm packages from getting bundled for deployed apps has been fixed. #7609.

  • The meteor update command now supports an --all-packages flag to update all packages (including indirect dependencies) to their latest compatible versions, similar to passing the names of all your packages to the meteor update command. #7653

  • Background release updates can now be disabled by invoking either meteor --no-release-check or METEOR_NO_RELEASE_CHECK=1 meteor. #7445

v1.4.0.1, 2016-07-29

  • Fix issue with the 1.4 tool springboarding to older releases (see Issue #7491)

  • Fix issue with running in development on Linux 32bit Issue #7511

v1.4, 2016-07-25

  • Node has been upgraded to 4.4.7.

  • The meteor-babel npm package has been upgraded to 0.11.7.

  • The reify npm package has been upgraded to 0.3.6.

  • The bcrypt npm package has been upgraded to 0.8.7.

  • Nested import declarations are now enabled for package code as well as application code. 699cf1f38e9b2a074169515d23983f74148c7223

  • Meteor has been upgraded to support Mongo 3.2 by default (the bundled version used by meteor run has been upgraded). Internally it now uses the 2.2.4 version of the mongodb npm driver, and has been tested against at Mongo 3.2 server. Issue #6957

    Mongo 3.2 defaults to the new WiredTiger storage engine. You can update your database following the instructions here: https://docs.mongodb.com/v3.0/release-notes/3.0-upgrade/. In development, you can also just use meteor reset to remove your old database, and Meteor will create a new WiredTiger database for you. The Mongo driver will continue to work with the old MMAPv1 storage engine however.

    The new version of the Mongo driver has been tested with MongoDB versions from 2.6 up. Mongo 2.4 has now reached end-of-life (https://www.mongodb.com/support-policy), and is no longer supported.

    If you are setting MONGO_OPLOG_URL, especially in production, ensure you are passing in the replicaSet argument (see [#7450] (https://github.com/meteor/meteor/issues/7450))

  • Custom Mongo options can now be specified using the Mongo.setConnectionOptions(options) API. #7277

  • On the server, cursor.count() now takes a single argument applySkipLimit (see the corresponding [Mongo documentation] (http://mongodb.github.io/node-mongodb-native/2.1/api/Cursor.html#count))

  • Fix for regression caused by #5837 which incorrectly rewrote network-path references (e.g. //domain.com/image.gif) in CSS URLs. #7416

  • Added Angular2 boilerplate example #7364

v1.3.5.1, 2016-07-18

  • This release fixed a small bug in 1.3.5 that prevented updating apps whose .meteor/release files refer to releases no longer installed in ~/.meteor/packages/meteor-tool. 576468eae8d8dd7c1fe2fa381ac51dee5cb792cd

v1.3.5, 2016-07-16

  • Failed Meteor package downloads are now automatically resumed from the point of failure, up to ten times, with a five-second delay between attempts. #7399

  • If an app has no package.json file, all packages in node_modules will be built into the production bundle. In other words, make sure you have a package.json file if you want to benefit from devDependencies pruning. 7b2193188fc9e297eefc841ce6035825164f0684

  • Binary npm dependencies of compiler plugins are now automatically rebuilt when Node/V8 versions change. #7297

  • Because .meteor/local is where purely local information should be stored, the .meteor/dev_bundle link has been renamed to .meteor/local/dev_bundle.

  • The .meteor/local/dev_bundle link now corresponds exactly to .meteor/release even when an app is using an older version of Meteor. d732c2e649794f350238d515153f7fb71969c526

  • When recompiling binary npm packages, the npm rebuild command now receives the flags --update-binary and --no-bin-links, in addition to respecting the $METEOR_NPM_REBUILD_FLAGS environment variable. #7401

  • The last solution found by the package version constraint solver is now stored in .meteor/local/resolver-result-cache.json so that it need not be recomputed every time Meteor starts up.

  • If the $GYP_MSVS_VERSION environment variable is not explicitly provided to meteor {node,npm}, the node-gyp tool will infer the appropriate version (though it still defaults to "2015").

v1.3.4.4, 2016-07-10

  • Fixed #7374.

  • The default loglevel for internal npm commands (e.g., those related to Npm.depends) has been set to "error" instead of "warn". Note that this change does not affect meteor npm ... commands, which can be easily configured using .npmrc files or command-line flags. 0689cae25a3e0da3615a402cdd0bec94ce8455c8

v1.3.4.3, 2016-07-08

  • Node has been upgraded to 0.10.46.

  • npm has been upgraded to 3.10.5.

  • The node-gyp npm package has been upgraded to 3.4.0.

  • The node-pre-gyp npm package has been upgraded to 0.6.29.

  • The ~/.meteor/meteor symlink (or AppData\Local\.meteor\meteor.bat on Windows) will now be updated properly after meteor update succeeds. This was promised in v1.3.4.2 but not fully delivered.

  • The .meteor/dev_bundle symbolic link introduced in v1.3.4.2 is now updated whenever .meteor/release is read.

  • The .meteor/dev_bundle symbolic link is now ignored by .meteor/.gitignore.

v1.3.4.2, 2016-07-07

  • The meteor node and meteor npm commands now respect .meteor/release when resolving which versions of node and npm to invoke. Note that you must meteor update to 1.3.4.2 before this logic will take effect, but it will work in all app directories after updating, even those pinned to older versions. #7338

  • The Meteor installer now has the ability to resume downloads, so installing Meteor on a spotty internet connection should be more reliable. #7348

  • When running meteor test, shared directories are symlinked (or junction-linked on Windows) into the temporary test directory, not copied, leading to much faster test start times after the initial build. The directories: .meteor/local/{bundler-cache,isopacks,plugin-cache}

  • App.appendToConfig allows adding custom tags to config.xml. #7307

  • When using ROOT_URL with a path, relative CSS URLs are rewriten accordingly. #5837

  • Fixed bugs: #7149 #7296 #7309 #7312

v1.3.4.1, 2016-06-23

v1.3.4, 2016-06-22

  • The version of npm used by meteor npm and when installing Npm.depends dependencies of Meteor packages has been upgraded from 2.15.1 to 3.9.6, which should lead to much flatter node_modules dependency trees.

  • The meteor-babel npm package has been upgraded to 0.11.6, and is now installed using npm@3.9.6, fixing bugs arising from Windows path limits, such as #7247.

  • The reify npm package has been upgraded to 0.3.4, fixing #7250.

  • Thanks to caching improvements for the files.{stat,lstat,readdir,realpath} methods and PackageSource#_findSources, development server restart times are no longer proportional to the number of files in node_modules directories. #7253 #7008

  • When installed via InstallMeteor.exe on Windows, Meteor can now be easily uninstalled through the "Programs and Features" control panel.

  • HTTP requests made by the meteor command-line tool now have a timeout of 30 seconds, which can be adjusted by the $TIMEOUT_SCALE_FACTOR environment variable. #7143

  • The request npm dependency of the http package has been upgraded from 2.53.0 to 2.72.0.

  • The --headless option is now supported by meteor test and meteor test-packages, in addition to meteor self-test. #7245

  • Miscellaneous fixed bugs: #7255 #7239

v1.3.3.1, 2016-06-17

  • Fixed bugs: #7226 #7181 #7221 #7215 #7217

  • The node-aes-gcm npm package used by oauth-encryption has been upgraded to 0.1.5. #7217

  • The reify module compiler has been upgraded to 0.3.3.

  • The meteor-babel package has been upgraded to 0.11.4.

  • The pathwatcher npm package has been upgraded to 6.7.0.

  • In CoffeeScript files with raw JavaScript enclosed by backticks, the compiled JS will no longer contain require calls inserted by Babel. #7226

  • Code related to the Velocity testing system has been removed. #7235

  • Allow smtps:// in MAIL_URL #7043

  • Adds Accounts.onLogout() a hook directly analogous to Accounts.onLogin(). PR #6889

v1.3.3, 2016-06-10

  • Node has been upgraded from 0.10.43 to 0.10.45.

  • npm has been upgraded from 2.14.22 to 2.15.1.

  • The fibers package has been upgraded to 1.0.13.

  • The meteor-babel package has been upgraded to 0.10.9.

  • The meteor-promise package has been upgraded to 0.7.1, a breaking change for code that uses Promise.denodeify, Promise.nodeify, Function.prototype.async, or Function.prototype.asyncApply, since those APIs have been removed.

  • Meteor packages with binary npm dependencies are now automatically rebuilt using npm rebuild whenever the version of Node or V8 changes, making it much simpler to use Meteor with different versions of Node. 5dc51d39ecc9e8e342884f3b4f8a489f734b4352

  • *.min.js files are no longer minified during the build process. PR #6986 Issue #5363

  • You can now pick where the .meteor/local directory is created by setting the METEOR_LOCAL_DIR environment variable. This lets you run multiple instances of the same Meteor app. PR #6760 Issue #6532

  • Allow using authType in Facebook login PR #5694

  • Adds flush() method to Tracker to force recomputation PR #4710

  • Adds defineMutationMethods option (default: true) to new Mongo.Collection to override default behavior that sets up mutation methods (/collection/[insert|update...]) PR #5778

  • Allow overridding the default warehouse url by specifying METEOR_WAREHOUSE_URLBASE PR #7054

  • Allow _id in $setOnInsert in Minimongo: https://github.com/meteor/meteor/pull/7066

  • Added support for $eq to Minimongo: https://github.com/meteor/meteor/pull/4235

  • Insert a Date header into emails by default: https://github.com/meteor/meteor/pull/6916/files

  • meteor test now supports setting the bind address using --port IP:PORT the same as meteor run PR #6964 Issue #6961

  • Meteor.apply now takes a noRetry option to opt-out of automatically retrying non-idempotent methods on connection blips: PR #6180

  • DDP callbacks are now batched on the client side. This means that after a DDP message arrives, the local DDP client will batch changes for a minimum of 5ms (configurable via bufferedWritesInterval) and a maximum of 500ms (configurable via bufferedWritesMaxAge) before calling any callbacks (such as cursor observe callbacks).

  • PhantomJS is no longer included in the Meteor dev bundle (#6905). If you previously relied on PhantomJS for local testing, the spiderable package, Velocity tests, or testing Meteor from a checkout, you should now install PhantomJS yourself, by running the following commmand: meteor npm install -g phantomjs-prebuilt

  • The babel-compiler package now looks for .babelrc files and package.json files with a "babel" section. If found, these files may contribute additional Babel transforms that run before the usual babel-preset-meteor set of transforms. In other words, if you don't like the way babel-preset-meteor handles a particular kind of syntax, you can add your preferred transform plugins to the "presets" or "plugins" section of your .babelrc or package.json file. #6351

  • When BabelCompiler cannot resolve a Babel plugin or preset package in .babelrc or package.json, it now merely warns instead of crashing. #7179

  • Compiler plugins can now import npm packages that are visible to their input files using inputFile.require(id). b16e8d50194b37d3511889b316345f31d689b020

  • import statements in application modules now declare normal variables for the symbols that are imported, making it significantly easier to inspect imported variables when debugging in the browser console or in meteor shell.

  • import statements in application modules are no longer restricted to the top level, and may now appear inside conditional statements (e.g. if (Meteor.isServer) { import ... }) or in nested scopes.

  • import statements now work as expected in meteor shell. #6271

  • Commands installed in dev_bundle/lib/node_modules/.bin (such as node-gyp and node-pre-gyp) are now available to scripts run by meteor npm. e95dfe410e1b43e8131bc2df9d2c29decdd1eaf6

  • When building an application using meteor build, "devDependencies" listed in package.json are no longer copied into the bundle. #6750

  • Packages tested with meteor test-packages now have access to local node_modules directories installed in the parent application or in the package directory itself. #6827

  • You no longer need to specify DEPLOY_HOSTNAME=galaxy.meteor.com to run meteor deploy (and similar commands) against Galaxy. The AWS us-east-1 Galaxy is now the default for DEPLOY_HOSTNAME. If your app's DNS points to another Galaxy region, meteor deploy will detect that automatically as well. #7055

  • The coffeescript plugin now passes raw JavaScript code enclosed by back-ticks to BabelCompiler, enabling all ECMAScript features (including import and export) within CoffeeScript. #6000 #6691

  • The coffeescript package now implies the same runtime environment as ecmascript (ecmascript-runtime, babel-runtime, and promise, but not modules). #7184

  • When Meteor packages install npm dependencies, the process.env.NPM_CONFIG_REGISTRY environment variable is now respected. #7162

  • files.rename now always executes synchronously. 9856d1d418a4d19c0adf22ec9a92f7ce81a23b05

  • "Bare" files contained by client/compatibility/ directories or added with api.addFiles(path, ..., { bare: true }) are no longer compiled by Babel. https://github.com/meteor/meteor/pull/7033#issuecomment-225126778

  • Miscellaneous fixed bugs: #6877 #6843 #6881

v1.3.2.4, 2016-04-20

Meteor 1.3.2.4 was published because publishing 1.3.2.3 failed in an unrecoverable way. Meteor 1.3.2.4 contains no additional changes beyond the changes in 1.3.2.3.

v1.3.2.3, 2016-04-20

  • Reverted accidental changes included in 1.3.2.1 and 1.3.2.2 that improved DDP performance by batching updates, but broke some packages that relied on private methods of the DDP client Connection class. See https://github.com/meteor/meteor/pull/5680 for more details. These changes will be reinstated in 1.3.3.

v1.3.2.2, 2016-04-18

  • Fixed bugs #6819 and #6831.

v1.3.2.1, 2016-04-15

  • Fixed faulty comparison of .sourcePath and .targetPath properties of files scanned by the ImportScanner, which caused problems for apps using the tap:i18n package. 6e792a7cf25847b8cd5d5664a0ff45c9fffd9e57

v1.3.2, 2016-04-15

  • The meteor/meteor repository now includes a Roadmap.md file: https://github.com/meteor/meteor/blob/devel/Roadmap.md

  • Running npm install in bundle/programs/server when deploying an app also rebuilds any binary npm dependencies, fixing #6537. Set METEOR_SKIP_NPM_REBUILD=1 to disable this behavior if necessary.

  • Non-.js(on) files in node_modules (such as .less and .scss) are now processed by compiler plugins and may be imported by JS. #6037

  • The jquery package can now be completely removed from any app (#6563), and uses <app>/node_modules/jquery if available (#6626).

  • Source maps are once again generated for all bundled JS files, even if they are merely identity mappings, so that the files appear distinct in the browser, and stack traces make more sense. #6639

  • All application files in imports directories are now considered lazy, regardless of whether the app is using the modules package. This could be a breaking change for 1.3.2 apps that do not use modules or ecmascript but contain imports directories. Workaround: move files out of imports, or rename imports to something else.

  • The npm-bcrypt package has been upgraded to use the latest version (0.8.5) of the bcrypt npm package.

  • Compiler plugins can call addJavaScript({ path }) multiple times with different paths for the same source file, and module.id will reflect this path instead of the source path, if they are different. #6806

  • Fixed bugs: https://github.com/meteor/meteor/milestones/Release%201.3.2

  • Fixed unintended change to Match.Optional which caused it to behave the same as the new Match.Maybe and incorrectly matching null where it previously would not have allowed it. #6735

v1.3.1, 2016-04-03

  • Long isopacket node_modules paths have been shortened, fixing upgrade problems on Windows. #6609

  • Version 1.3.1 of Meteor can now publish packages for earlier versions of Meteor, provided those packages do not rely on modules. #6484 #6618

  • The meteor-babel npm package used by babel-compiler has been upgraded to version 0.8.4. c8d12aed4e725217efbe86fa35de5d5e56d73c83

  • The meteor node and meteor npm commands now return the same exit codes as their child processes. #6673 #6675

  • Missing module warnings are no longer printed for Meteor packages, or for require calls when require is not a free variable, fixing https://github.com/practicalmeteor/meteor-mocha/issues/19.

  • Cordova iOS builds are no longer built by Meteor, but merely prepared for building. 88d43a0f16a484a5716050cb7de8066b126c7b28

  • Compiler plugin errors were formerly silenced for files not explicitly added in package.js. Now those errors are reported when/if the files are imported by the ImportScanner. be986fd70926c9dd8eff6d8866205f236c8562c4

v1.3, 2016-03-27

ES2015/Modules

  • Enable ES2015 and CommonJS modules in Meteor apps and packages, on both client and server. Also let you install modules in apps and package by running npm install. See: https://github.com/meteor/meteor/blob/master/packages/modules/README.md

  • Enable ES2015 generators and ES2016 async/await in the ecmascript package.

  • Inherit static getters and setters in subclasses, when using the ecmascript package. #5624

  • Report full file paths on compiler errors when using the ecmascript package. #5551

  • Now possible to import or require files with a .json file extension. #5810

  • process.env.NODE_ENV is now defined on both client and server as either development or production, which also determines the boolean flags Meteor.isDevelopment and Meteor.isProduction.

  • Absolute identifiers for app modules no longer have the /app/ prefix, and absolute identifiers for Meteor packages now have the prefix /node_modules/meteor/ instead of just /node_modules/, meaning you should import {Blaze} from "meteor/blaze" instead of from "blaze".

  • Package variables imported by application code are once again exposed globally, allowing them to be accessed from the browser console or from meteor shell. #5868

  • Fixed global variable assignment analysis during linking. #5870 #5819

  • Changes to files in node_modules will now trigger a restart of the development server, just like any other file changes. #5815

  • The meteor package now exports a global variable (a la Node) that provides a reliable reference to the global object for all Meteor code.

  • Packages in local node_modules directories now take precedence over Meteor packages of the same name. #5933

  • Upgraded babel-compiler to Babel 6, with the following set of plugins: https://github.com/meteor/babel-preset-meteor/blob/master/index.js

  • Lazy CSS modules may now be imported by JS: 12c946ee651a93725f243f790c7919de3d445a19

  • Packages in the top-level node_modules directory of an app can now be imported by Meteor packages: c631d3ac35f5ca418b93c454f521989855b8ec72

  • Added support for wildcard import and export statements. #5872 #5897

  • Client-side stubs for built-in Node modules are now provided automatically if the meteor-node-stubs npm package is installed. #6056

  • Imported file extensions are now optional for file types handled by compiler plugins. #6151

  • Upgraded Babel packages to ~6.5.0: 292824da3f8449afd1cd39fcd71acd415c809c0f Note: .babelrc files are now ignored (#6016), but may be reenabled (#6351).

  • Polyfills now provided for process.nextTick and process.platform. #6167 #6198 #6055 efe53de492da6df785f1cbef2799d1d2b492a939

  • The meteor test-app command is now meteor test [--full-app]: ab5ab15768136d55c76d51072e746d80b45ec181

  • New apps now include a package.json file. c51b8cf7ffd8e7c9ca93768a2df93e4b552c199c

  • On the server, modules contained within node_modules directories are now loaded using the native Node require function. #6398

  • All <script> tag(s) for application and package code now appear at the end of the <body> rather than in the <head>. #6375

  • The client-side version of process.env.NODE_ENV (and other environment variables) now matches the corresponding server-side values. #6399

Performance

  • Don't reload package catalog from disk on rebuilds unless package dependencies changed. #5747

  • Improve minimongo performance on updating documents when there are many active observes. #5627

Platform

  • Upgrade to Node v0.10.41.

  • Allow all types of URLs that npm supports in Npm.depends declarations.

  • Split up standard-minifiers in separate CSS (standard-minifiers-css) and JS minifiers (standard-minifiers-js). standard-minifiers now acts as an umbrella package for these 2 minifiers.

  • Allow piping commands to meteor shell via STDIN. #5575

  • Let users set the CAFILE environment variable to override the SSL root certificate list. #4757 #5523

  • force-ssl is now marked production only.

Cordova

  • Cordova dependencies have been upgraded to the latest versions (cordova-lib 6.0.0, cordova-ios 4.0.1, and cordova-android 5.1.0).

  • iOS apps now require iOS 8 or higher, and building for iOS requires Xcode 7.2 to be installed.

  • Building for Android now requires Android SDK 23 to be installed. You may also need to create a new AVD for the emulator.

  • Building Cordova Android apps on Windows is now supported. #4155

  • The Crosswalk plugin has been updated to 1.4.0.

  • Cordova core plugins are now pinned to minimal versions known to be compatible with the included platforms. A warning is printed asking people to upgrade their dependencies if they specify an older version, but we'll always use the pinned version regardless.

  • The plugin used for file serving and hot code push has been completely rewritten. Among many other improvements, it downloads updates incrementally, can recover from downloading faulty JavaScript code, and is much more reliable and performant. See cordova-plugin-meteor-webapp for more a more detailed description of the new design.

  • If the callbacks added with Meteor.startup() do not complete within a set time, we consider a downloaded version faulty and will fallback to the last known good version. The default timeout is 20 seconds, but this can be configured by setting App.setPreference("WebAppStartupTimeout", "10000"); (in milliseconds) in mobile-config.js.

  • We now use WKWebView on iOS by default, even on iOS 8 (which works because we do not use file:// URLs).

  • We now use localhost instead of meteor.local to serve files from. Since localhost is considered a secure origin, this means the web view won't disable web platform features that it otherwise would.

  • The local server port now lies between 12000-13000 and is chosen based on the appId, to both be consistent and lessen the chance of collisions between multiple Meteor Cordova apps installed on the same device.

  • The plugin now allows for local file access on both iOS and Android, using a special URL prefix (http://localhost:<port>/local-filesystem/<path>).

  • App icon and launch image sizes have been updated. Low resolution sizes for now unsupported devices have been deprecated, and higher resolution versions have been added.

  • We now support the modern Cordova whitelist mechanism. App.accessRule has been updated with new options.

  • meteor build now supports a --server-only option to avoid building the mobile apps when ios or android platforms have been added. It still builds the web.cordova architecture in the server bundle however, so it can be served for hot code pushes.

  • meteor run now always tries to use an autodetected IP address as the mobile ROOT_URL, even if we're not running on a device. This avoids a situation where an app already installed on a device connects to a restarted development server and receives a localhost ROOT_URL. #5973

  • Fixed a discrepancy between the way we calculated client hashes during a mobile build and on the server, which meant a Cordova app would always download a new version the first time it started up.

  • In Cordova apps, Meteor.startup() now correctly waits for the device to be ready before firing the callback.

Accounts

  • Make Accounts.forgotPassword treat emails as case insensitive, as the rest of the accounts system does.

Blaze

  • Don't throw in certain cases when calling a template helper with an empty data context. #5411 #5736

  • Improve automatic blocking of URLs in attribute values to also include vbscript: URLs.

Check

  • Introduced new matcher Match.Maybe(type) which will also match (permit) null in addition to undefined. This is a suggested replacement (where appropriate) for Match.Optional which did not permit null. This prevents the need to use Match.OneOf(null, undefined, type). #6220

Testing

  • Packages can now be marked as testOnly to only run as part of app testing with meteor test. This is achieved by setting testOnly: true to Package.describe.

Uncategorized

  • Remove warning in the simple-todos-react example app. #5716

  • Fix interaction between browser-policy and oauth packages. #5628

  • Add README.md to the tinytest package. #5750

  • Don't crash when calling ReactiveDict.prototype.clear if a property with a value wasn't previously accessed. #5530 #5602

  • Move DDPRateLimiter to the server only, since it won't work if it is called from the client. It will now error if referenced from the client at all.

  • Don't call function more than once when passing a Match.Where argument to check. #5630 #5651

  • Fix empty object argument check in this.subscribe in templates. #5620

  • Make HTTP.call not crash on undefined content. #5565 #5601

  • Return observe handle from Mongo.Collection.prototype._publishCursor. #4983 #5615

  • Add 'Did you mean?' reminders for some CLI commands to help Rails developers. #5593

  • Make internal shell scripts compatible with other Unix-like systems. #5585

  • Add a _pollingInterval option to coll.find() that can be used in conjunction with _disableOplog: true. #5586

  • Expose Tinytest internals which can be used to extend it. #3541

  • Improve error message from check when passing in null. #5545

  • Split up standard-minifiers in separate CSS (standard-minifier-css) and JS minifiers(standard-minifier-js). standard-minifiers now acts as an umbrella package for these 2 minifiers.

  • Detect new Facebook user-agent in the spiderable package. #5516

  • Match.ObjectIncluding now really requires plain objects. #6140

  • Allow git+ URL schemes for npm dependencies. #844

  • Expose options disableOplog, pollingIntervalMs, and pollingThrottleMs to Cursor.find for tuning observe parameters on the server.

  • Expose dynamicHead and dynamicBody hooks in boilerplate generation allowing code to inject content into the body and head tags from the server. #3860

  • Add methods of the form BrowserPolicy.content.allow<ContentType>BlobUrl() to BrowserPolicy #5141

  • Move <script> tags to end of <body> to enable 'loading' UI to be inserted into the boilerplate #6375

  • Adds WebAppInternals.setBundledJsCssUrlRewriteHook allowing apps to supply a hook function that can create a dynamic bundledJsCssPrefix at runtime. This is useful if you're using a CDN by giving you a way to ensure the CDN won't cache broken js/css resources during an app upgrade.

v.1.2.1, 2015-10-26

  • coll.insert() now uses a faster (but cryptographically insecure) algorithm to generate document IDs when called outside of a method and an _id field is not explicitly passed. With this change, there are no longer two algorithms used to generate document IDs. Random.id() can still be used to generate cryptographically secure document IDs. #5161

  • The ecmascript-collections package has been renamed to ecmascript-runtime and now includes a more complete selection of ES2015 polyfills and shims from core-js. The complete list can be found here.

  • Check type of onException argument to bindEnvironment. #5271

  • WebApp's PORT environment variable can now be a named pipe to better support deployment on IIS on Windows. 4413

  • Template.dynamic can be now used as a block helper: {{#Template.dynamic}} ... {{/Template.dynamic}} #4756

  • Collection#allow/deny now throw errors when passed falsy values. #5442

  • source-map has been updated to a newer patch version, which fixes major bugs in particular around loading bundles generated by Webpack. #5411

  • check now returns instead of throwing errors internally, which should make it much faster. check is used in many core Meteor packages, so this should result in small performance improvements across the framework. #4584

  • The userEmail option to Meteor.loginWithMeteorDeveloperAccount has been renamed to loginHint, and now supports Google accounts as well. The old option still works for backwards compatibility. #2422 #5313

  • The old addFiles API for adding package assets no longer throws an error, making it easier to share packages between pre- and post-1.2 versions of Meteor. #5458

  • Normally, you can't deploy to free meteor.com hosting or Galaxy from a non-Linux machine if you have local non-published packages with binary dependencies, nor can you run meteor build --architecture SomeOtherArch. As a temporary workaround, if you set the METEOR_BINARY_DEP_WORKAROUND variable, you will be able to deploy to Galaxy (but not free meteor.com hosting), and tarballs built with meteor build will contain a programs/server/setup.sh shell script which should be run on the server to install those packages.

v1.2.0.2, 2015-09-28

  • Update Crosswalk plugin for Cordova to 1.3.1. #5267

  • Fix meteor add for a Cordova plugin using a Git URL with SHA.

  • Upgraded the promise package to use meteor-promise@0.5.0, which uses the global Promise constructor in browsers that define it natively.

  • Fix error in assigning attributes to <body> tag when using Blaze templates or static-html. #5232

v1.2.0.1, 2015-09-22

  • Fix incorrect publishing of packages with exports but no source. #5228

v1.2, 2015-09-21

There are quite a lot of changes in Meteor 1.2. See the Wiki for a shorter list of breaking changes you should be aware of when upgrading.

Core Packages

  • meteor-platform has been deprecated in favor of the smaller meteor-base, with apps listing their other dependencies explicitly. The v1.2 upgrader will rewrite meteor-platform in existing apps. meteor-base puts fewer symbols in the global namepsace, so it's no longer true that all apps have symbols like Random and EJSON in the global namespace.

  • New packages: ecmascript, es5-shim, ecmascript-collections, promise, static-html, jshint, babel-compiler

  • No longer include the json package by default, which contains code for JSON.parse and JSON.stringify. (The last browser to not support JSON natively was Internet Explorer 7.)

  • autoupdate has been renamed hot-code-push

Meteor Accounts

  • Login attempts are now rate-limited by default. This can be turned off using Accounts.removeDefaultRateLimit().

  • loginWithPassword now matches username or email in a case insensitive manner. If there are multiple users with a username or email only differing in case, a case sensitive match is required. #550

  • loginWithGithub now requests user:email scope by default, and attempts to fetch the user's emails. If no public email has been set, we use the primary email instead. We also store the complete list of emails. #4545

  • When an account's email address is verified, deactivate other verification tokens. #4626

  • Fix bug where blank page is shown when an expired login token is present. #4825

  • Fix OAuth1Binding.prototype.call when making requests to Twitter with a large parameter set.

  • Directions for setting up Google OAuth in accounts-ui have been updated to match Google's new requirements.

  • Add Accounts.oauth.unregisterService method, and ensure that users can only log in with currently registered services. #4014

  • The accounts-base now defines reusable AccountsClient and AccountsServer constructors, so that users can create multiple independent instances of the Accounts namespace. #4233

  • Create an index for Meteor.users on services.email.verificationTokens.token (instead of emails.validationTokens.token, which never was used for anything). #4482

  • Remove an IE7-specific workaround from accounts-ui. #4485

Livequery

  • Improved server performance by reducing overhead of processing oplog after database writes. Improvements are most noticeable in case when a method is doing a lot of writes on collections with plenty of active observers. #4694

Mobile

  • The included Cordova tools have been updated to the latest version 5.2.0. This includes Cordova Android 4.1 and Cordova iOS 3.9. These updates may require you to make changes to your app. For details, see the [Cordova release notes] (https://cordova.apache.org/#news) for for the different versions.

  • Thanks to Cordova Android's support for pluggable web views, it is now possible to install the [Crosswalk plugin] (https://crosswalk-project.org/documentation/cordova/cordova_4.html), which offers a hugely improved web view on older Android versions. You can add the plugin to your app with meteor add crosswalk.

  • The bundled Android tools have been removed and a system-wide install of the Android SDK is now required. This should make it easier to keep the development toolchain up to date and helps avoid some difficult to diagnose failures. If you don't have your own Android tools installed already, you can find more information about installing the Android SDK for [Mac] (https://github.com/meteor/meteor/wiki/Mobile-Dev-Install:-Android-on-Mac) or [Linux] (https://github.com/meteor/meteor/wiki/Mobile-Dev-Install:-Android-on-Linux).

  • As part of moving to npm, many Cordova plugins have been renamed. Meteor should perform conversions automatically, but you may want to be aware of this to avoid surprises. See [here] (https://cordova.apache.org/announcements/2015/04/21/plugins-release-and-move-to-npm.html) for more information.

  • Installing plugins from the local filesystem is now supported using file:// URLs, which should make developing your own plugins more convenient. It is also needed as a temporary workaround for using the Facebook plugin. Relative references are interpreted relative to the Meteor project directory. (As an example, meteor add cordova:phonegap-facebook-plugin@file://../phonegap-facebook-plugin would attempt to install the plugin from the same directory you Meteor project directory is located in.)

  • Meteor no longer supports installing Cordova plugins from tarball URLs, but does support Git URLs with a SHA reference (like https://github.com/apache/cordova-plugin-file#c452f1a67f41cb1165c92555f0e721fbb07329cc). Existing GitHub tarball URLs are converted automatically.

  • Allow specifying a buildNumber in App.info, which is used to set the android-versionCode and ios-CFBundleVersion in the config.xml of the Cordova project. The build number is used to differentiate between different versions of the app, and should be incremented before distributing a built app to stores or testing services. #4048

  • Other changes include performance enhancements when building and running, and improved requirements checking and error reporting.

  • Known issue: we do not currently show logging output when running on the iOS Simulator. As a workaround, you can meteor run ios-device to open the project in Xcode and watch the output there.

Templates/Blaze

  • New syntax: Handlebars sub-expressions are now supported -- as in, {{helper (anotherHelper arg1 arg2)}} -- as well as new block helper forms #each .. in .. and #let x=y. See https://github.com/meteor/meteor/tree/devel/packages/spacebars

  • Add a special case for the new react-template-helper package -- don't let templates use {{> React}} with siblings since React.render assumes it's being rendered into an empty container element. (This lets us throw the error when compiling templates rather than when the app runs.)

  • Improve parsing of <script> and <style> tags. #3797

  • Fix a bug in observe-sequence. The bug was causing unnecessary rerenderings in an instance of #each block helper followed by false "duplicate ids" warnings. #4049

  • TemplateInstance#subscribe now has a new connection option, which specifies which connection should be used when making the subscription. The default is Meteor.connection, which is the connection used when calling Meteor.subscribe.

  • Fix external <script> tags in body or templates. #4415

  • Fix memory leak. #4289

  • Avoid recursion when materializing DOM elements, to avoid stack overflow errors in certain browsers. #3028

  • Blaze and Meteor's built-in templating are now removable using meteor remove blaze-html-templates. You can add back support for static head and body tags in .html files by using the static-html package.

DDP

  • Websockets now support the permessage-deflate extension, which compresses data on the wire. It is enabled by default on the server. To disable it, set $SERVER_WEBSOCKET_COMPRESSION to 0. To configure compression options, set $SERVER_WEBSOCKET_COMPRESSION to a JSON object that will be used as an argument to deflate.configure. Compression is supported on the client side by Meteor's Node DDP client and by browsers including Chrome, Safari, and Firefox 37.

  • The ddp package has been split into ddp-client and ddp-server packages; using ddp is equivalent to using both. This allows you to use the Node DDP client without adding the DDP server to your app. #4191 #3452

  • On the client, Meteor.call now takes a throwStubExceptions option; if set, exceptions thrown by method stubs will be thrown instead of logged, and the method will not be invoked on the server. #4202

  • sub.ready() should return true inside that subscription's onReady callback. #4614

  • Fix method calls causing broken state when socket is reconnecting. #5104

Isobuild

  • Build plugins will no longer process files whose names match the extension exactly (with no extra dot). If your build plugin needs to match filenames exactly, you should use the new build plugin API in this release which supplies a special filenames option. #3985

  • Adding the same file twice in the same package is now an error. Previously, this could either lead to the file being included multiple times, or to a build time crash.

  • You may now specify the bare option for JavaScript files on the server. Previous versions only allowed this on the client. #3681

  • Ignore node_modules directories in apps instead of processing them as Meteor source code. #4457 #4452

  • Backwards-incompatible change for package authors: Static assets in package.js files must now be explicitly declared by using addAssets instead of addFiles. Previously, any file that didn't have a source handler was automatically registered as a server-side asset. The isAsset option to addFiles is also deprecated in favor of addAssets.

  • Built files are now always annotated with line number comments, to improve the debugging experience in browsers that don't support source maps.

  • There is a completely new API for defining build plugins that cache their output. There are now special APIs for defining linters and minifiers in addition to compilers. The core Meteor packages for less, coffee, stylus and html files have been updated to use this new API. Read more on the Wiki page.

CSS

  • LESS and Stylus now support cross-package imports.

  • CSS concatenation and minification is delegated to the standard-minifiers package, which is present by default (and added to existing apps by the v1.2 upgrader).

  • CSS output is now split into multiple stylesheets to avoid hitting limits on rules per stylesheet in certain versions of Internet Explorer. #1876

Mongo

  • The oplog observe driver now properly updates queries when you drop a database. #3847

  • MongoID logic has been moved out of minimongo into a new package called mongo-id.

  • Fix Mongo upserts with dotted keys in selector. #4522
