When backporting PRs, do not forget to also include branch-3,0. And I've already started the release process for 3.0.0.
So about setting fix versions, now when patches go into master, you should set fix version 4.0.0-alpha-1, when patches go into branch-3, you should set fix version 3.1.0, and when patches go into branch-3.0, you should set fix version 3.0.1. You can follow rule from now on as I will adjust the fix versions if 3.0.0RC0 fails to be the final release. Thanks.
