I’m happy to announce two release candidates today: Python 3.9.2rc1, and Python
3.8.8rc1. Get them from:
https://www.python.org/downloads/release/python-392rc1/
<https://www.python.org/downloads/release/python-392rc1/>
https://www.python.org/downloads/release/python-388rc1/
<https://www.python.org/downloads/release/python-388rc1/>
Unless critical issues are discovered, both release candidates will become
their respective final versions on Monday, March 1st.
Following that, the last full regular maintenance release of Python 3.8 is
planned for May 3rd 2021, after which it will shift to source releases only for
security bug fixes only. Maintenance releases for the 3.9 series will continue
at regular bi-monthly intervals, with 3.9.3 planned for early May 2021.
Notable security content in today’s releases
bpo-42967 <https://bugs.python.org/issue42967>: Fix web cache poisoning
vulnerability by defaulting the query args separator to &, and allowing the
user to choose a custom separator.
bpo-42938 <https://bugs.python.org/issue42938>: Avoid static buffers when
computing the repr of ctypes.c_double and ctypes.c_longdouble values.
