Dancer2 0.205000 improves application speed, deprecates request->dispatch_path

Dancer2 0.205000 is on it’s way to CPAN, and brings with it a number of bug fixes, documentation improvements, and enhancements. The changes with the most potential impact to your existing applications include:

  • Migrating from MooX::Types to Type::Tiny. This will improve the speed of any Dancer2 application automatically.

  • Deprecating request->dispatch_path. This was originally introduced to fix a buggy request->path implementation; fixing request->path caused dispatch_path to incorrectly fail a route match when SCRIPT_NAME was also a prefix of the PATH_INFO. request->path now functions as intended, and is the preferred method of dispatch. request->dispatch_path will throw a warning if used, and will call request->path instead. The method will be removed entirely two releases from now.

  • A new method is being added to Dancer2 applications, prepare_app(). This method will eventually get called automatically when to_app() is invoked. In preparation of this, any application that may already contain a prepare_app() method will complain - loudly - that implementation of this method is coming. Expect to see the final implementation of prepare_app() two releases from now.

Finally, this release saw a large number of community contributions, especially from first-time contributors. The Dancer Core Team is extremely appreciative of the efforts by its users - thanks so much for making Dancer an even better framework!
