"Michael #1: PEP 814 - Add frozendict built-in type by Victor Stinner & Donghee Na A 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."
"Michael #3: Tach Keep the streak: pip deps with uv + tach From Gerben Decker We 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!)"
PEP 814 introduces a frozendict built-in immutable dictionary type to the builtins module. Frozendict is designed to be safe by preventing unintended modifications and to benefit both the CPython standard library and third-party maintainers by providing a reliable immutable mapping. Tach is used to lint dependency structures, combined with custom rules and an underused ruff feature invoked via "uv run ruff analyze graph --python python_exe_path .". There are notes about pip dependency management with uv + tach and references to Python speedups in versions 3.15 and 3.16. Announcements include a live YouTube stream and a friends-of-the-show email list.
