Odd: https://wiki.freebsd.org/Python currently says 3.12 is WIP to be made the default... while pkg tells me it's vulnerable, and 3.15 is the current upstream release, and pkg says:

"python315-3.15.0 Pre-release versions of the interpreted object-oriented programming language"

I guess the wiki […]

Python 3.15 is here — UTF-8 default everywhere, lazy imports, new sentinel and frozendict builtins, and a faster JIT. Here's what the release changes for working developers: capturedtech.com/Home/Post/8902 #Python #Python315

On GitHub Actions, python-version: '3.x' gets 3.14 by default. Once runner-images#14911 caches 3.15, it gets 3.15, and pip can quietly install old releases of anything capped <3.15. 59 top-3,000 PyPI projects cap.

Python 3.15: pip can quietly install years-old releases of your dependencies
Some popular packages declare a requires_python that stops below 3.15, for example >=3.10,<3.15. On Python 3.15, pip does not report that.

The new #python315 profiling tools are great, managed to find and remove some hotspots with the heatmap and flamegraph visualisations. All those tools existed before, but beeing part of Python stdlib makes them way more accessible. A great addition to the toolbelt.
