When we announced the previous EAP build, we mentioned that we had two new features with the letter 'C' in development. Now we're happy to announce that we have not two, but three of them, and all of them are included in today's EAP:
Initial support for Cython. The current version supports only syntax and error highlighting; other features (such as code navigation and completion) will be added in the coming weeks.
The new CoffeeScript plugin, with code insight, formatter and inspections support, is now bundled with PyCharm.
PyCharm now supports collecting and displaying code coverage info
