We've uploaded 3.1.2 release on our official download site at jetbrains.com.
This release build number is 6881. We've uploaded 6878 build yesterday, but quickly after that (thanks to one of our attentive users) a problem has been found with connections to Subversion with "svn+ssh" protocol. It turned out we forget to add one of the jars of SVNKit library that we use to access Subversion repositories. A new build with the problem fixed has been uploaded just several minutes ago.
P.S. If you are already use one of Calcutta EAP builds, just stay tuned. In a week or a bit more we will release a next EAP build with more features included!
