# Update to NixOS 24.11 An occasional chores, we've updated the flake to be based off [NixOS 24.11](https://nixos.org/blog/announcements/2024/nixos-2411/). From our understanding, the flake input could always be changed but this sets up a nice default using the current, non-deprecated version of NixOS. This came with a couple surprising changes, mostly in behavior from our tools. In specific, `treefmt` got a lot noisier with 24.11 when it came to unknown files in the repository (like `.php` files we we don't have set up). Modifications were made to the linked `treefmt.toml` file to not report those to avoid a wall of text when there were a lot of them.
