Okay, time to schedule some major rewrites. I noticed the deprecation warnings when moving platforms to Ubuntu recently, and now the version removing the APIs has been released.
DeprecationWarning: 'cgitb' is deprecated and slated for removal in Python 3.13
DeprecationWarning: 'cgi' is deprecated and slated for removal in Python 3.13Meanwhile, let's just change the shebang to "python3.12" instead of "python3"...

π2οΈβ£π The **final** release candidate of Python 3.13 is out!
β‘οΈ Library maintainers, please upload wheels to PyPI **now**, especially if you have compiled extensions (there are no more ABI changes), so everything is in place for the big 3.13.0 release in 3 weeks!
π Also! Security releases have been made for the full set of Python 3.8 - 3.12. Please upgrade!

ππ§΅π Big thanks to @lysnikolaou of Quansight Labs for helping us get @pillow ready for free-threaded Python 3.13 (we did some work at the @europython sprints).
See https://labs.quansight.org/blog/free-threaded-python-rollout and https://py-free-threading.github.io to learn more.
We also upload nightly free-threaded (cp313t) wheels to help the community test:
https://anaconda.org/scientific-python-nightly-wheels/pillow/And we'll upload them to PyPI as part of the Q3 release in October.

π1οΈβ£π The first of two Python 3.13 release candidates is out now!
"Call to action
"We strongly encourage maintainers of third-party Python projects to prepare their projects for 3.13 compatibilities during this phase, and where necessary publish Python 3.13 wheels on PyPI to be ready for the final release of 3.13.0. Any binary wheels built against Python 3.13.0rc1 **will work** with future versions of Python 3.13."

ππ§ͺ Python 3.13 beta 2 is out!
https://discuss.python.org/t/3-13-0b2-now-available/55056
The macOS installer joins the Windows installer in adding an option to install free-threaded binaries as python3.13t, making it even easier to try it out.
See https://github.com/python/cpython/issues/120098 for all the details, and https://dev.to/hugovk/help-us-test-free-threaded-python-without-the-gil-1hgf for an overview.

ππ§ͺ Python 3.13.0 is due out in October 2024 and work is underway to implement *experimental support* for PEP 703 "Making the Global Interpreter Lock Optional in CPython".
As the Steering Council noted in their acceptance of the PEP, to succeed it's important to have community support.
I wrote a little guide on how you can help test out the beta in your project, and help us find bugs in CPython:
