Dancer2 0.202000 is on its way to a CPAN mirror near you, and brings several important bug fixes and enhancements.

Plugins may now easily call the application’s DSL using $self->dsl. For example, logging a debugging message is as easy as $self->dsl->debug( “I’m in your plugin!” ); Plugins can now also call the syntax of plugins that they have loaded. Consider this example:

Your Dancer2 application (MyApp) uses plugin Foo. Plugin Foo uses plugin Bar. Plugin Bar adds baz() to the DSL. Plugin Foo can now access baz() (just like the DSL in Dancer2 works), however, baz() is only accessible to the Foo plugin, not MyApp.

Please keep in mind that if plugin Bar adds any hooks, those hooks are added to MyApp, but Bar’s DSL is not available to MyApp.

The parameter methods in Dancer2 (body_parameters(), etc.) were not decoding Unicode values passed to them. All parameter methods are now decoding Unicode characters.

There have been several maintenance issues regarding Type::Tiny::XS, and these were causing compilation and runtime failures for users of Dancer2 on Strawberry Perl. Until these issues are resolved, we have returned to using MooX::Types::MooseLike for type checking. If you’re a plugin author, please check your plugin against this release as this change may require some reworking on your part. Please find us on irc.perl.org#dancer with any questions or help you may need.

A memory leak was uncovered in Dancer2::Plugin, and has been patched in this release. A test has been added to check for this in the future.

If you have HTTP::XSCookies installed, we will now use it, and cookie operations will be substantially faster.

The full changelog is as follows:
