Hello @JhonKkk
It seems Riccardo is absent for now and Darkchaos as i recall had some different work.
So i belive it should be fine if you want make new JME release yourself, like Sgold suggested.
I think this topic might be very usefull resource: 3.6 release and 3.6.1 release topic:
Ofc every project have different ways to make pull requests. Some ways were to create release branch first and later merge to master.
But in JME i think you create pull request directly into Master, and later create release TAG and branch from master for a release.
I see there are branches for 3.6 but i guess its related for a Fixes/subversions like 3.6.1.
@sgold or @Ali_RS if you could help clarify here would be cool
example pull request:
There is also contribution mega-thread:
But for a new release, as can notice, some fixes/features are picked to merge and then create release.
Your work itself IMO might be enough for new release itself.
