Edit: Digging in a bit, a lot of things are slightly bigger overall as you'd expect; but notably the documentation folder has gained two animated GIFs totaling over 10MB (which presumably don't compress too much further even with XZ) demonstrating "tachyon" (which presumably refers to the new sampling profiler, https://docs.python.org/3.15/library/profiling.sampling.html ). These seem to be screen captures from terminal sessions, which work well enough to illustrate what a TUI looks like, but are probably not all that informative about how to use it. I would have much preferred SVG diagrams based around static screenshots.

Nice to see improvements here!

Here's the "what's new in Python 3.11" document: https://docs.python.org/3/whatsnew/3.11.html

Yes lazy import! Finally!

I’m particularly proud that the cryptography project is already shipping a single abi3.abi3t wheel for each platform on Python 3.15 or newer. The GIL-enabled build and free-threaded build can both use the same wheel now, because PyObject is opaque.

If you want to learn more about this, I gave a talk at EuroPython this year on Python’s ABI and the road to building and releasing abi3t today. See https://youtu.be/An8lO29SxXE.
