We’re happy to announce the beginning of the Early Access Preview program for the next version of RubyMine, version 2.5.
The biggest new feature of RubyMine 2.5 is support for Rails 3. RubyMine now correctly runs the renamed Rails scripts, and many of the code insight features have been updated to handle the Rails 3 codebase correctly. Of course, what we have now is work in progress – some features may still not work, and you’re welcome to report any problems that you run into when migrating your projects to Rails 3. And by the way, RubyMine is now capable of highlighting usages of features which are deprecated in Rails 3, and we plan to provide additional migration tools in the final 2.5 release.
There are also a number of smaller improvements, for example, the reworked IRB and Rails consoles. More details are listed in the release notes.
RubyMine 2.5 EAP is available for download now. Each build can be used for free (no license required) for 30 days since its release date; when a EAP build expires, you can download a new one and continue using RubyMine 2.5.
As for the further plans, we plan to have RubyMine 2.5 beta ready by RailsConf (beginning of June), and the final release soon after that.
