This is it! We are down to THE FINAL WEEK for 3.7.0! Please get your
feature fixes, bug fixes, and documentation updates in before
2018-05-21 ~23:59 Anywhere on Earth (UTC-12:00). That's about 7 days
from now. We will then tag and produce the 3.7.0 release candidate.
Our goal continues been to be to have no changes between the release
candidate and final; AFTER NEXT WEEK'S RC1, CHANGES APPLIED TO THE 3.7
BRANCH WILL BE RELEASED IN 3.7.1. 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. Those of us who are
participating in the development sprints at PyCon US 2018 here in
Cleveland can feel the excitement building as we work through the
remaining issues, including completing the "What's New in 3.7"
document and final feature documentation. (We wish you could all be

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

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!

Release Managerly Yours,
