|
|
============
|
|
|
|
|
|
2020-06-30 13:31:06 -04:00
|
|
|
3.8 will receive bugfix updates approximately every 2 months for
|
|
|
|
|
approximately 18 months. Some time after the release of 3.9.0 final,
|
2024-10-07 13:56:09 -04:00
|
|
|
the ninth and final 3.8 bugfix update was released. After that,
|
|
|
|
|
security updates (source only) were released for 5 years until the
|
|
|
|
|
release of Python 3.13.0 final.
|
|
|
|
|
|
|
|
|
|
As of 2024-10-07, 3.8 has reached the
|
|
|
|
|
`end-of-life phase <https://devguide.python.org/devcycle/#end-of-life-branches>`_
|
|
|
|
|
of its release cycle. 3.8.20 was the final security release.
|
|
|
|
|
The codebase for 3.8 is now frozen and no further updates will be
|
|
|
|
|
provided nor issues of any kind will be accepted on the bug tracker.
