As scheduled, Python 3.8.1 has arrived a week before Christmas. This maintenance release includes some further changes compared to the RC that was released 11 days prior. For this year, it marks the last release on the Python 3.8 branch, as v3.8.2 is scheduled for February 2020.

Library updates
Python 3.8.1 closes the issue bpo-39022, submitted by jaraco earlier this month, that stated importlib.metadata should be synchronized with importlib_metadata 1.3. importlib.metadata now comes with improvements from importlib_metadata 1.3 regarding aspects such as serialization of EntryPoints and documentation for custom finders.
The issue of pathlib crashing when os.link() was missing has been resolved as well, and an error raised by doctest.testmod(empty_package) has been fixed by adding a patch.

Further changes
Bug fixes include that lineno and col_offset are now consistent with the “if” node parsing an “elif” node, as they point to the “elif” keyword. The new API PySys_Audit previously raised a deprecation warning when using “#” format strings, but this issue has now also been closed.
