 Hydra is a [Continuous Integration](https://en.wikipedia.org/wiki/Continuous_integration) service for [Nix](https://nixos.org/nix) based projects.

+| `lix-2.91` | [2.91](https://lix.systems/blog/2024-08-12-lix-2.91-release/) | ✅ |

+Active development happens on `main` only.
+Branches that track a Lix release are maintained as long as the Lix version is
+maintained. These only receive critical bugfixes.
