This is the end of the road for Python 3.9 in nixpkgs. End of security suport after 2025-10-31, and therefore not suitable for NixOS 25.05.

This breaks

  • cjdns (needs an update, but that wasn't straightforward) @ehmry
  • crossfire-server (still not migrated away from that one parser) @ToxicFrog

Still broken from Python 3.8

  • gcc-arm-embedded (they will never migrate away from 3.8, will they?) @prusnak @prtzl

Things done

  • Built on platform(s)
    • x86_64-linux
    • aarch64-linux
    • x86_64-darwin
    • aarch64-darwin
  • For non-Linux: Is sandboxing enabled in nix.conf? (See Nix manual)
    • sandbox = relaxed
    • sandbox = true
  • Tested, as applicable:
  • Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
  • Tested basic functionality of all binary files (usually in ./result/bin/)
  • 25.05 Release Notes (or backporting 24.11 and 25.05 Release notes)
    • (Package updates) Added a release notes entry if the change is major or breaking
    • (Module updates) Added a release notes entry if the change is significant
    • (Module addition) Added a release notes entry if adding a new NixOS module
  • Fits CONTRIBUTING.md.

easyabc has a small issue (can't find ghostscript) but that can be fixed later. Good to be merged 👍

gcc-arm-embedded fixed in #398190 where Python support is removed

No version we have in nixpkgs is older than 3.20.
End of security support is scheduled for 2025-10-31, which does not cover
the complete 25.05 release cycle.
The packages set is now gone and pytorch has been renamed to just torch.
