Python 3.7.7rc1, the release preview of the next maintenance release of Python 3.7, is now available for testing. Assuming no critical problems are found prior to 2020-02-10 2020-03-10, no code changes are planned between this release candidate and the final release. The release candidate is intended to give you the opportunity to test the new security and bug fixes in 3.7.7. While we strive to not introduce any incompatibilities in new maintenance releases, we encourage you to test your projects and report issues found to bugs.python.org as soon as possible. Please keep in mind that, since this is a preview release, its use is not recommended for production environments.
