Hi everyone,

This is a friendly reminder from the release manager team that Python 3.10 feature freeze is two weeks away (Monday, 3 May 2021).

Please, be aware of the following:

• No new features or improvements should be merged after feature freeze. From the devguide (https://devguide.python.org/devcycle/#beta) :

After a first beta release is published, no new features are accepted. Only bug fixes can now be committed. This is when core developers should concentrate on the task of fixing regressions and other new issues filed by users who have downloaded the alpha and beta release

• If your change involves some platform-specific behaviour or has a non-trivial amount of C code, make sure you run the buildbots in your Pull Request by using the "test-with-buildbots" label ( https://discuss.python.org/t/now-you-can-test-a-pr-with-the-buildbots-before... ). Alternatively you could check the buildbots post-merge in the buildbot server: https://buildbot.python.org/all/#/builders?tags=%2B3.x&tags=%2Bstable This is very important because if problems are detected at the time of the release, the release management team may have to revert the changes and therefore those will not be included in Python 3.10.

• The master branch will be renamed to main (check our previous communication about how this will be done and how you should proceed: https://mail.python.org/archives/list/python-dev@python.org/thread/QWW7KGBW5... )

If you have any questions or concerns, please contact me as soon as possible.
