Most likely the final revision in 3.1 branch is available. We wanted to release all pending bugfixes that we had worked on, before the next feature release. The 3.2.0 should be out in the next week or two.
This release brings couple of minor improvements of UI and updates GitHub authenticator configuration to use newly recommended settings. The most important bugfix is related to image loading in administrative interfaces.
3.1.4 is available from Downloads
