Python 3.8.2rc1 is the release candidate of the second maintenance release of Python 3.8. Go get it here:
That being said, please keep in mind that this is a pre-release of 3.8.2 and as such its main purpose is testing.
Maintenance releases for the 3.8 series will continue at regular bi-monthly intervals, with 3.8.3 planned for April 2020 (during sprints at PyCon US).
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 3.8.2 specifically can be found in its change log.
