   Starting with release 25.05, the minimum supported version will be macOS Big Sur 11, and we cannot guarantee that packages will continue to work on older versions of macOS.
   Users on old macOS versions should consider upgrading to a supported version (potentially using [OpenCore Legacy Patcher](https://dortania.github.io/OpenCore-Legacy-Patcher/) for old hardware) or installing NixOS.
   If neither of those options are viable and you require new versions of software, [MacPorts](https://www.macports.org/) supports back to Mac OS X Snow Leopard 10.6.
+- Nix was updated to 2.24, which brings a lot of improvements and fixes. See the release notes for
+    [2.19](https://nix.dev/manual/nix/latest/release-notes/rl-2.19),
+    [2.20](https://nix.dev/manual/nix/latest/release-notes/rl-2.20),
+    [2.21](https://nix.dev/manual/nix/latest/release-notes/rl-2.21),
+    [2.22](https://nix.dev/manual/nix/latest/release-notes/rl-2.22),
+    [2.23](https://nix.dev/manual/nix/latest/release-notes/rl-2.23),
+    [2.24](https://nix.dev/manual/nix/latest/release-notes/rl-2.24).
+  Notable changes include improvements to Git fetching, documentation comment support in `nix-repl> :doc`, as well as many quality of life improvements.
 
 - Convenience options for `amdgpu`, open source driver for Radeon cards, is now available under `hardware.amdgpu`.
