Brian #1: Python 3.13.0 released Oct 7

Michael #2: PEP 759 – External Wheel Hosting

pypi.org ships over 66 petabytes / month backed by Fastly
There are hard project size limits for publishers to PyPI
We can host the essence of a .whl as a .rim file, then allow an external download URL
Security: Several factors as described in this proposal should mitigate security concerns with externally hosted wheels, such as:
- Wheel file checksums MUST be included in .rim files, and once uploaded cannot be changed. Since the checksum stored on PyPI is immutable and required, it is not possible to spoof an external wheel file, even if the owning organization lost control of their hosting domain.
- Externally hosted wheels MUST be served over HTTPS.
- In order to serve externally hosted wheels, organizations MUST be approved by the PyPI admins.

Brian #3: pytest-freethreaded

PyCon JP 2024 Team:
- This extension was created at PyCon JP sprints with Anthony Shaw and 7 other folks listed in credits.
“A pytest plugin for helping verify that your tests and libraries are thread-safe with the Python 3.13 experimental freethreaded mode.”
Testing your project for compatibility with freethreaded Python.
- Testing in single thread doesn’t test that.
- Neither does testing with pytest-xdist, because it uses multiprocessing to parallelize tests.
- So, Ant and others “made this plugin to help you run your tests in a thread-pool with the GIL disabled, to help you identify if your tests are thread-safe.”
- “And the first library we tested it on (which was marked as compatible) caused a segmentation fault in CPython! So you should give this a go if you're a package maintainer.”
