0.16.510 Apr 2018 -
0.16.421 Mar 2018Release notes

0.16.019 Oct 2017Release notes
Open source →- BREAKING CHANGE: Require that the examples to message/plural/gender/select
calls be const. DDC does not optimize non-const maps well, so it's a
significant performance issue if these are non-const.
- Added a utility to convert examples in calls to be const. See bin/make_examples_const.dart
- Add a codegen_mode flag, which can be either release or debug. In release mode a missing translation throws an exception, in debug mode it returns the original text, which was the previous behavior.
- Add support for generating translated messages as JSON rather than methods. This can significantly improve dart2js compile times for applications with many translations. The JSON is a literal string in the deferred library, so usage doesn't change at all.
- BREAKING CHANGE: Require that the examples to message/plural/gender/select
calls be const. DDC does not optimize non-const maps well, so it's a
significant performance issue if these are non-const.

0.15.005 Jun 2017Release notes
Open source →- API overhaul:
- Getting rid of the Intl object, as it only served as a wrapper of Locale. So the ...Format objects are now the top-level things.
- Remove most ...Options objects from the public API, as they make it more verbose. Users now directly input the options to the top-level ...Format constructor.
- Use => instead of block bodies for methods where possible.
- Fix some imports
- Add documentation to some classes.
- Remove some methods which are not implemented in ICU4X
Release notes
Open source →- Change non-transformer message rewriting to preserve the original message as
much as possible. Adds --useStringSubstitution command-line arg.
- Change non-transformer message rewriting to allow multiple input files to be specified on the command line. Adds --replace flag to ignore --output option and just replace files.
- Make non-transformer message rewriting also run dartfmt on the output.
- Make message extraction more robust: error message instead of stack trace when an Intl call is made outside a method, when a prefixed expression is used in an interpolation, and when a non-required example Map is not a literal.
- Make message extraction more robust: if parsing triggers an exception then report it as an error instead of exiting.
- Move barback to being a normal rather than a dev dependency.
- Add a check for invalid select keywords.
- Added a post-message construction validate, moved IntlMessageExtractionException into intl_message.dart
- Make use of analyzer's new AstFactory class (requires analyzer version 0.29.1).
- Fix error in transformer, pass the path instead of the asset id.
- Prefer an explicit =0/=1/=2 to a ZERO/ONE/TWO if both are present. We don't distinguish the two as Intl.message arguments, we just have the "one" parameter, which we confusingly write out as =1. Tools interpret these differently, and in particular, a ONE clause is used for the zero case if there's no explicit zero. Translation tools may implement this by filling in both ZERO and ONE values with the OTHER clause when there's no ZERO provided, resulting in a translation with both =1 and ONE clauses which are different. We should prefer the explicit =1 in that case. In future we may distinguish the different forms, but that would probably break existing translations.
- Switch to using package:test
- Give a more specific type in the generated code to keep lints happy.
- API overhaul:
-
0.14.002 Sep 2016Release notes
