    RE: https://code4lib.social/@acdha/116558806694701121 Do not use pull_request_target. Do not use caches in publish workflows. Use dependency cooldowns. Use Zizmor. Tell GitHub to make Actions secure by default. #GitHub #GitHubActions

    RE: https://mastodon.social/@hugovk/116534312819614916 Just as importantly! After two years, it&amp;#39;s now time to ceremoniously hand over the `main` branch to @savannah! `main` is now accepting new features for Python 3.16, and I bet it&amp;#39;s going to be even better than 3.15. https://peps.python.org/pep-0826/ #Python #Python315 #Python316

    The day before feature freeze, the CPython team is busy reviewing last minute PRs, but today&amp;#39;s latest #GitHub outage is eating review comments. We are resorting to pasting screenshots of reviews around in PRs and DMs. https://github.com/python/cpython/pull/148827/#issuecomment-4390256894

    Do you use astral-sh/setup-uv@v7 in #GitHubActions? And it&amp;#39;s not hash-pinned? And you use #Dependabot or #Renovate? The setup-uv project has switched to only Vx.y.z tags, no more Vx or Vx.y. But Dependabot and Renovate won&amp;#39;t upgrade from Vx to Vx.y.z, so you&amp;#39;ll need to manually update to setup-uv@v8.0.0 to keep up with future updates. &amp;quot;To increase security even more we will stop publishing minor tags. You won&amp;#39;t be able to use v8 or v8.0 any longer.&...

    Who would like Rust in CPython 3.15? @emmatyping and Kirill Podoprigora &amp;quot;propose introducing the Rust programming language to CPython. Rust will initially only be allowed for writing optional extension modules, but eventually will become a required dependency of CPython and allowed to be used throughout the CPython code base.&amp;quot; https://discuss.python.org/t/pre-pep-rust-for-cpython/104906 #Python #Python315 #CPython #Rust
