1.2.0

  • Have the compiler treat several user-generated invalid responses as compilation errors rather than ProtocolErrors:

    • Invalid function signatures in CompileRequest.global_functions.

    • Non-absolute URLs in CanonicalizeResponse.result.url, ImportSuccess.source_map_url, and FileImportResponse.result.file_url.

  • Clarify that an invalid signature in a HostFunction should treat the current function as failing, rather than the HostFunction.

1.1.0

  • Add a charset option that controls whether or not Sass emits a @charset/BOM for non-ASCII stylesheets.

1.0.0

  • First stable release.

1.0.0-beta.18

  • Add a CompileRequest.source_map_include_sources field that tells the compiler to embed the contents of all source files in the generated source maps.

1.0.0-beta.17

  • Mark ImportResponse.result as optional. Importers should be able to return null to indicate that a file wasn't found.

1.0.0-beta.16

  • Mark CompileFailure.span as mandatory. There's no instance where a compilation itself should fail without having a source to point to.

  • Make it the compiler's responsibility to verify HostFunction.signature. This ensures that the host doesn't have to parse Sass code.

1.0.0-beta.15

  • Pluralize Calculation.arguments.

  • Explicitly document how hosts should handle calculations.

1.0.0-beta.14

  • Add support for calculation values.

1.0.0-beta.13

  • Add the Value.HwbColor type.

  • Explicitly specify that compilers may choose which color types to use to represent each color.

1.0.0-beta.12

  • Add the Value.ArgumentList type, as well as FunctionCallResponse.accessed_argument_lists to track which argument lists had their keywords accessed.

1.0.0-beta.11

  • Breaking change: We now follow the protocol buffer style guide. This means:

    • Field names are now all underscore-separated rather than lower camel case.
    • Enums are now at the top-level with prefixes rather than surrounded in enclosing messages.

  • Add CompileRequest.quiet_deps and CompileRequest.verbose flags to control how the compiler emits compilation warnings.

  • Add a CompileSuccess.loaded_urls field that indicates the URLs that were loaded by a compilation.

  • Clarify that CompileRequest.StringInput.url must be a canonical URL.

  • Fix the documentation of CanonicalizeRequest to avoid referring to the outmoded CanonicalizeResponse.result.file field.

1.0.0-beta.10

  • Add VersionRequest.id and VersionResponse.id.

1.0.0-beta.9

  • Added CanonicalizeRequest.fromImport and FileImportRequest.fromImport fields to allow importers to correctly handle import-only files.

1.0.0-beta.8

  • Added fields to support requesting and sending formatted errors and logs.

    • CompileRequest.alert_color
    • CompileRequest.alert_ascii
    • CompileFailure.formatted
    • LogEvent.formatted

  • Remove OutputStyle.NESTED and OutputStyle.COMPACT. It's unlikely that any host would support those any time soon.

1.0.0-beta.7

  • Use 4294967295 as the special ID for error messages that aren't caused by a specific request, since -1 isn't representable as a uint32.

1.0.0-beta.6

  • Changed CompileResponse.id and ProtocolError.id from int32 to uint32 to match the type of all other ID fields.

  • Added protocol versions and created this changelog.

  • Added the VersionRequest and VersionResponse messages.

  • Delimit messages with varints rather than fixed-size integers.
