0.11.1

DFX

fix: dfx now only adds candid:service metadata to custom canisters that have at least one build step

This way, if a canister uses a premade canister wasm, dfx will use it as-is.

fix: "canister alias not defined" in the Motoko language server

It is now possible to develop multiple-canister projects using the Motoko VSCode extension.

fix: improve browser compatibility for the JavaScript language binding

Patches a JavaScript language binding compatibility issue encountered in web browsers which do not support the (?.) operator.

feat: print dfx.json schema

dfx is now capable of displaying the schema for dfx.json. You can see the schema by running dfx schema or write the schema to a file with dfx schema --outfile path/to/file/schema.json.

feat: support for configuring assets in assets canister

• The .ic-assets.json file should be placed inside directory with assets, or its subdirectories. Multiple config files can be used (nested in subdirectories). Example of .ic-assets.json file format:

[
    {
        "match": ".*",
        "cache": {
            "max_age": 20
        },
        "headers": {
            "X-Content-Type-Options": "nosniff"
        },
        "ignore": false
    },
    {
        "match": "**/*",
        "headers": null
    },
    {
        "match": "file.json",
        "ignore": true
    }
]

• Configuring assets works only during asset creation - any changes to .ic-assets.json files won't have any effect effect for assets that have already been created. We are working on follow up implementation with improvements to handle updating these properties.

• headers from multiple applicable rules are being stacked/concatenated, unless null is specified, which resets/empties the headers.

• Both "headers": {} and absence of headers field don't have any effect on end result.

• Valid JSON format is required, i.e. the array of maps, match field is required. Only the following fields are accepted: cache, ignore, headers, match. The glob pattern has to be valid.

• The way matching rules work:

  1. The most deeply nested config file takes precedence over the one in parent dir. In other words, properties from a rule matching a file in a subdirectory override properties from a rule matching a file in a parent directory
  2. Order of rules within file matters - last rule in config file takes precedence over the first one

• The way ignore field works:

  1. By default, files that begin with a . are ignored, while all other files are included.
  2. The .ignore field overrides this, if present.
  3. If a directory is ignored, file and directories within it cannot be un-ignored.
  4. A file can be ignored and un-ignored many times, as long as any of its parent directories haven't been ignored.

fix: Allow dfx deploy to not take arguments for canisters not being installed

A longstanding bug with dfx deploy is that if an installation is skipped (usually an implicitly included dependency), it still requires arguments even if the installed canister doesn't. As of this release that bug is now fixed.

feat: Add additional logging from bitcoin canister in replica.

Configures the replica to emit additional logging from the bitcoin canister whenever the bitcoin feature is enabled. This helps show useful information to developers, such as the bitcoin height that the replica currently sees.

fix: make build field optional for custom canisters

Prior to 0.11.0, a custom canister's build field could be left off if dfx build was never invoked. To aid in deploying prebuilt canisters, this behavior is now formalized; omitting build is equivalent to build: [].

feat: Use --locked for Rust canisters

dfx build, in Rust canisters, now uses the --locked flag when building with Cargo. To offset this, dfx new --type rust now runs cargo update on the resulting project.

feat: Enable threshold ecdsa signature

ECDSA signature signing is now enabled by default in new projects, or by running dfx start --clean.
A test key id "Secp256k1:dfx_test_key" is ready to be used by locally created canisters.
