So, the 3.1 stable release has been uploaded which, other than a version change, is the same as beta4. This is the announcement that most of you will care about because it means you can go ahead and start using it. It's up on bintray/jcenter and up on github.
I've walked this release through most steps of its later life and I don't have time to compile proper user-friendly release notes. Expect a more formal and shinier announcement soon, I hope. Even the current github page is a bit of a placeholder:
...but if you want to see the whole giant 3.0 - 3.1 changelog, you can hit it there or at this link: https://github.com/jMonkeyEngine/jmonkeyengine/releases/download/v3.1.0-stable/v3.1.0-stable-logs-clean.txt
(email addresses removed to protect us all from spambots)
Further fixes on the 3.1 branch will go through a much more rapid release cycle. For example, if a 3.1.1 is needed then it will collect patches then go straight to 3.1.1-rc1. Presuming that stands then we'll go straight to 3.1.1-stable.
This is to assuage any fears that 3.1 is somehow static now and no bugs will be fixed... because I know there are probably still issues with 3.1 for some folks.
For the folks that put power in a name, now our stable code has a stable name and we can stop talking about that.
