Michael #0: Black Friday is on at Talk Python What’s on offer: An AI course mini bundle (22% off)20% off our entire library via the Everything Bundle (what's that? ;) )The new Talk Python in Production book (25% off) Brian: This is peer pressure in action 20% off The Complete pytest Course bundle (use code BLACKFRIDAY) through November or use save50 for 50% off, your choice.Python Testing with pytest, 2nd edition, eBook (50% off with code save50) also through November I would have picked 20%, but it’s a PragProg wide thing Michael #1: PEP 814 – Add frozendict built-in type by Victor Stinner & Donghee NaA new public immutable type frozendict is added to the builtins module.We expect frozendict to be safe by design, as it prevents any unintended modifications. This addition benefits not only CPython’s standard library, but also third-party maintainers who can take advantage of a reliable, immutable dictionary type.To add to existing frozen types in Python. Brian #2: From Material for MkDocs to Zensical Suggested by John HagenA lot of people, me included, use Material for MkDocs as our MkDocs theme for both personal and professional projects, and in-house docs.This plugin for MkDocs is now in maintenance modeThe development team is switching to working on Zensical, a static site generator to overcome some technical limitations with MkDocs. There’s a series of posts about the transition and reasoning Transforming Material for MkDocsZensical – A modern static site generator built by the creators of Material for MkDocsMaterial for MkDocs Insiders – Now free for everyoneGoodbye, GitHub DiscussionsMaterial for MkDocs still around, but in maintenance modeall insider features now available to everyoneZensical is / will be compatible with Material for Mkdocs, can natively read mkdocs.yml, to assist with the transitionOpen Source, MIT licensefunded by an offering for professional users: Zensical Spark Michael #3: Tach Keep the streak: pip deps with uv + tachFrom Gerben DeckerWe needed some more control over linting our dependency structure, both internal and external.We use tach (which you covered before IIRC), but also some home built linting rules for our specific structure. These are extremely easy to build using an underused feature of ruff: "uv run ruff analyze graph --python python_exe_path .".Example from an app I’m working on (shhhhh not yet announced!) Brian #4: Some Python Speedups in 3.15 and 3.16 A Plan for 5-10%* Faster Free-Threaded JIT by Python 3.16 5% faster by 3.15 and 10% faster by 3.16Decompression is up to 30% faster in CPython 3.15 Extras Brian: LeanTDD book issue tracker Michael: No. 4 for dependencies: Inverted dep trees from Bob Belderbos Joke: git pull inception
