If you're updating `nixVersions.stable`, follow all the steps mentioned above, but use the **staging** branch for your pull request (or **staging-next** after coordinating with the people in matrix `#staging:nixos.org`)

This is necessary because, at the end of the staging-next cycle, the NixOS tests are built through the [staging-next-small](https://hydra.nixos.org/jobset/nixos/staging-next-small) jobset.

Especially nixos installer test are important to look at here.



There is a script to update minor versions:



```

./pkgs/tools/package-management/nix/update-all.sh

```
