<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->

- Cinnamon has been updated to 6.0. Please beware that the [Wayland session](https://blog.linuxmint.com/?p=4591) is still experimental in this release.

- Programs written in [Nim](https://nim-lang.org/) are built with libraries selected by lockfiles.

  The `nimPackages` and `nim2Packages` sets have been removed.

  See https://nixos.org/manual/nixpkgs/unstable#nim for more information.
