Michael #1: <a href="https://discuss.python.org/t/pep-814-add-frozendict-built-in-type/104854?featured_on=pythonbytes">PEP 814 – Add frozendict built-in type</a>

<ul>
<li>by Victor Stinner & Donghee Na</li>
<li>A new public immutable type <code>frozendict</code> is added to the <code>builtins</code> module.</li>
<li>We expect <code>frozendict</code> 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.</li>
<li>To add to <a href="https://blobs.pythonbytes.fm/existing-frozen-typesstructures-in-python.html?cache_id=be7da5">existing frozen types in Python</a>.</li>

Brian #2: From <a href="https://squidfunk.github.io/mkdocs-material/?featured_on=pythonbytes">Material for MkDocs</a> to <a href="https://zensical.org?featured_on=pythonbytes">Zensical</a>

<ul>
<li>Suggested by John Hagen</li>
<li>A lot of people, me included, use Material for MkDocs as our MkDocs theme for both personal and professional projects, and in-house docs.</li>
<li>This plugin for MkDocs is <a href="https://github.com/squidfunk/mkdocs-material/issues/8523?featured_on=pythonbytes">now in maintenance mode</a></li>
<li>The 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

Michael #3: <a href="https://github.com/tach-org/tach?featured_on=pythonbytes">Tach</a>

<ul>
<li>Keep the streak: pip deps with uv + tach</li>
<li>From Gerben Decker</li>
<li>We needed some more control over linting our dependency structure, both internal and external.</li>
<li>We use <code>tach</code> (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 <code>ruff</code>: "uv run ruff analyze graph --python python_exe_path .".</li>
