Python 3.8.3rc1 is the release candidate of the third maintenance release of Python 3.8. Go get it here:
Assuming no critical problems are found prior to 2020-05-11, the scheduled release date for 3.8.3, no code changes are planned between this release candidate and the final release.
That being said, please keep in mind that this is a pre-release and as such its main purpose is testing.
Maintenance releases for the 3.8 series will continue at regular bi-monthly intervals, with 3.8.4 planned for mid-July 2020.
The Python 3.8 series is the newest feature release of the Python language, and it contains many new features and optimizations. See the “What’s New in Python 3.8 ” document for more information about features included in the 3.8 series.
Detailed information about all changes made in version 3.8.3 specifically can be found in its change log.
We hope you enjoy Python 3.8!
