Yet another Dancer2 release hitting CPAN as we speak, all the way from Granada, Spain, courtesy of YAPC::EU 2015. We've made a few interesting changes, highlights of which I would like to share with you. **Fixes** * Escaping file paths in regexes. * Handle response in before hook correctly when serializer available. * Correctly validate *all* options in route definition. * Custom error templates fixes, including in before hooks. * Unmask exceptions thrown by serializers. **Enhancements** * Major optimizations! Dancer 2 is now at least as fast as Dancer 1. We're continuing work on optimizing it. If you have use-cases you would like us to take a closer look at, just let us know! * Better stack trace display. * Correctly set response content via "halt" keyword. * Switch to HTML5 templates! * Streamline and optimize serializer helpers (`to_json`, `from_json`). **Thanks** We want to thank our lovely contributors for this release (in alphabetical order): A. Sinan Unur, Achilles Kars, Andy Beverley, Dmitrii Tcyganov, Gabor Szabo, Kadir, Nick Tonkin, Patrick Zimmermann, Tina Müller, Vernon, and, of course, our core devs involved in this release: Alberto Simões, Mickey Nasriachi, Russell Jenkins, Sawyer X. **Future plans** We intend to introduce one major change and deprecate unsafe behavior. We have a branch ready (which will be merged only *after* this release) that introduces three new keywords: `query_parameters`, `body_parameters`, and `route_parameters`. These will return values that make it unnecessary to validate whether you received a single value or multiple values. It's a change we've wanted to introduce for a while now. We also plan to deprecate the ability to set route parameters that undermine two specific features in route matching: splat/megasplat and regex captures. Unless you have `:splat` or `:captures` placeholder variables in your route definitions, you will not even notice. Have a great dance, :) Sawyer and the Dancer Core Dev Team.
