This is the final update email for the python3-first goal for the Stein development cycle [0]. We have achieved several benefits by completing the goal this cycle. Our documentation, release notes, linter, and release artifact build jobs use python 3 by default, most projects have unit tests running under python 3.6, and most projects have some form of function or integration test using python 3 [1]. All of those allow us to move forward with allowing teams to drop python 2 support after the Train cycle [2]. Besides the python 3 benefits, teams have their Zuul settings in their repository, which relieves a lot of the review burden on the centralized infrastructure team and allows teams to more easily manage their test jobs. Thank you to everyone who contributed to writing and reviewing patches. The community put in an immense amount of work on this goal during Stein. We had over 4000 patches tagged "python3-first" created by 57 contributors and reviewed (and approved) by more than 200 reviewers. I would like to extend a special thank you to our goal champions, Nguyễn Trí Hải (nguyentrihai93@gmail.com), Ma Lei (ma.lei@99cloud.net), and Huang Zhiping (huang.zhiping@99cloud.net) for creating and shepherding so many of those patches. And also to Andreas Jaegar, Clark Boylan, and the rest of the infrastructure team for their assistance in planning the Zuul migration and reviewing so many of the patches. The work on this goal this cycle proves to me that when our community comes together and focuses on a problem, we can make the big changes necessary to solve it. Thank you, Doug As mentioned earlier [3], I have abandoned the python3-first patches that I proposed earlier this cycle and that have not been merged. They're still there in gerrit, so if you find you need them it should be possible for someone to recover them. I left the few patches created by other authors alone [4].
