today we are starting the Zero Hydra Failures (in short ZHF) campaign for the upcoming NixOS release 25.05 (“Warbler”).
This campaign focuses on stabilization of the package set and tests for the upcoming release planned for 2025-05-23. This campaign ends then.
Everyone is welcomed so contribute to that effort so that we can ideally resolve all job failures. We especially also welcome new contributors! This is a great way and time to start contributing to Nixpkgs!
You can find more information and detailed instructions over on GitHub in the issue #403336.
Do Nix just get a new branch just on the release day from the nixos-unstable branch? Like from a particular commit on that day? Or a new branch started from previous commits with some criteria?
