Symfony 3.1.0 released

Symfony 3.1.0 has just been released. As always, backward compatibility means that you should be able to upgrade easily without changing anything in your code.

We've started to blog about the great new features that comes with 3.1 (more blog posts on their way), but here is a curated list of the most relevant ones:

Thank you all, and congrats! :)
This is great, however if your using phpunit to run your tests you should wait before using this version https://github.com/symfony/symfony/issues/18903
Awesome! Symfony 2.8 to 3.1 upgrade time :)
great news!!
Awesome !
Thank ;)
good news everyone!
Wow! Perfect!
Cache Component!!! I was on way to implement my own. But I didn't, cuz lack of time. Cache cache cache, isn't cache cool xD
So 3.2 and 2.3 are crossing each other, one is starting, the other is leaving...

I didn't see any officiel announcement about the end of bug fix support for 2.3, the first LTS, should the next bugfix PRs be based on 2.7 now?
Will the 2.3 certification be removed in the following days?
