Now we have RubyMine build 113.13 and it seems to be lucky to become the release candidate 2. Download and try it if you aren’t afraid of the number 13. You’ll find a lot of fixes there with a main focus on LESS. The whole list is available in release notes.
Please stay tuned at these last days before the release. Your feedback is very welcome as always and even more.
Develop with pleasure!
