-Changelog for versions previous to v0.1.9 are located at http://nunjucks.tumblr.com/.
+Changelog is available at https://github.com/mozilla/nunjucks/releases
 
-# v1.0.6 (August 15, 2014)
-
-* Added the `addGlobal` method to the Environment object
-* import/extends/include now can take an arbitrary expression
-* fix bugs in `set`
-* improve express integration (allows rendering templates without an extension)
-
-# v1.0.5 (May 1, 2014)
-
-* Added support for browserify
-* Added option to specify template output path when precompiling templates
-* Keep version comment in browser minified files
-* Speed up SafeString implementation
-* Handle null and non-matching cases for word count filter
-* Added support for node-webkit
-* Other various minor bugfixes
-
-# v1.0.4 (April 4, 2014)
-
-* Use v0.8.2 of chokidar from NPM rather than Github
-
-# v1.0.2 (March 25, 2014)
-
-* Use chokidar for watching file changes. This should fix a lot of problems on OS X machines.
-* Always use `/` in paths when precompiling templates
-* Fix bug where async filters hang indefinitely inside `if` statements
-* Extensions now can override autoescaping with an `autoescape` property
-* Other various minor bugfixes
-
-# v1.0.1 (December 16, 2013)
-
-This is mostly bugfix and code cleanup release. The only added things are:
-
-* New `nunjucks.compile` function which takes a string and returns a `Template` object
-* The `urlize` filter has been added
-
-# v1.0.0 (October 24, 2013)
-
-We've hit 1.0! Thanks for helping nunjucks stabilize and become
-awesome. I've added many good features recently and several people
-have been using them, and everything seems stable. I think it's time
-to cut 1.0.
-
-## Big changes:
-
-* An asynchronous API is now available, and async filters, extensions, and
-  loaders is supported. The async API is optional and if you don't do
-  anything async (the default), nothing changes for you. You can read
-  more about this
-  [here](http://jlongster.github.io/nunjucks/api.html#asynchronous-support). (fixes #41)
-* Much simpler higher-level API for initiating/configuring nunjucks is
-  available. Read more
-  [here](http://jlongster.github.io/nunjucks/api.html#simple-api).
-* An official grunt plugin is available for precompiling templates: [grunt-nunjucks](https://github.com/jlongster/grunt-nunjucks)
-* **The browser files have been renamed**. nunjucks.js is now the full
-    library with compiler, and nunjucks-slim.js is the small version
-    that only works with precompiled templates
-
-## Smaller changes:
-
-* urlencode filter has been added
-* The express integration has been refactored and isn't a kludge
-  anymore. Should avoid some bugs and be more future-proof;
-* The order in which variables are lookup up in the context and frame
-  lookup has been reversed. It will now look in the frame first, and
-  then the context. This means that if a `for` loop introduces a new
-  var, like `{% for name in names %}`, and if you have `name` in the
-  context as well, it will properly reference `name` from the for loop
-  inside the loop. (fixes #122 and #119)
-
-# v0.1.10 (August 9, 2013)
-
-This is a minor version update that includes several bugfixes.
-
-* fix hang when parsing an unclosed string that hits the end of file (fixes #85)
-* Adds IE8 support
-* `super()` calls are marked safe by default if using autoescaping
-* exposed a `markSafe` function in the runtime module for marking strings as safe inside filters
-* iterating over any "falsey" values will output nothing
-* make "this" be the context object in filters (fixes #109)
-
-# v0.1.9 (May 31, 2013)
-
-* autoescaping ([docs](http://nunjucks.jlongster.com/api#Autoescaping))
-* support for custom tags ([docs](http://nunjucks.jlongster.com/api#Custom-Tags-%2526-Extensions))
-* the API for the `Environment` object changed slightly ([docs](http://nunjucks.jlongster.com/api#new-Environment%28%255Bloaders%255D%252C-%255Boptions%255D%29))
-* tests now use expect.js instead of should.js, can be run [in the browser](http://jlongster.github.io/nunjucks/tests/browser/)!
-* ternary conditional operator added (foo if bar else baz)
-* various optimizations, compilation is now 1.4x faster
-* fix too aggressive caching of templates from HTTP loader
-* truncate filter has been added
-* improve title filter
-* many improvements to error messages
-* add AMD support for precompiled templates
-* fix multiple levels of super (issue #61)
-* support passing a single file to nunjucks-precompile
-* fix usage of `set` in an `if` block
-* fixed passing a false-y value as the last argument to a macro
-* `range`, `cycler`, and `joiner` globals have been added
-* fix nested blocks
-* add bower.json so the client-side lib can be installed through bower
