  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'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's going to be even better than 3.15. https://peps.python.org/pep-0826/ #Python #Python315 #Python316

  Do you use astral-sh/setup-uv@v7 in #GitHubActions? And it'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't upgrade from Vx to Vx.y.z, so you'll need to manually update to setup-uv@v8.0.0 to keep up with future updates. "To increase security even more we will stop publishing minor tags. You won't be able to use v8 or v8.0 any longer.&...
