Just a reminder that 3.7.0b4 is almost upon us. Please get your feature fixes, bug fixes, and documentation updates in before 2018-04-30 ~23:59 Anywhere on Earth (UTC-12:00). That's about 16 hours from now.
IMPORTANT: We are now in the final phase of 3.7.0. Tomorrow's 3.7.0b4 is the final beta planned for 3.7.0. After tomorrow, the next planned release is the 3.7.0 release candidate, on 2018-05-21, for final testing. Our goal is to have no changes between the release candidate and final; after rc1, changes applied to the 3.7 branch will be released in 3.7.1. Between now and the rc1 cutoff, please double-check that there are no critical problems outstanding and that documentation for new features in 3.7 is complete (including NEWS and What's New items), and that 3.7 is getting exposure and tested with our various platorms and third-party distributions and applications. Also, during the time leading up to the release candidate, we will be completing the What's New in 3.7 document.
As noted before, the ABI for 3.7.0 was frozen as of 3.7.0b3. You should now be treating the 3.7 branch as if it were already released and in maintenance mode. That means you should only push the kinds of changes that are appropriate for a maintenance release: non-ABI-changing bug and feature fixes and documentation updates. If you find a problem that requires an ABI-altering or other significant user-facing change (for example, something likely to introduce an incompatibility with existing users' code or require rebuilding of user extension modules), please make sure to set the b.p.o issue to "release blocker" priority and describe there why you feel the change is necessary. If you are reviewing PRs for 3.7 (and please do!), be on the lookout for and flag potential incompatibilities (we've all made them).
Thanks again for all of your hard work towards making 3.7.0 yet another great release - coming to a website near you on 06-15!
