+- The initial Incus LTS release (v6.0.x) is now available through `virtualisation.incus` as the default. Users who wish to continue using the non-LTS release will need to set `virtualisation.incus.package = pkgs.incus`. Stable release users are encouraged to stay on the LTS release as non-LTS releases will by default not be backported.
+
+- Canonical LXD has been upgraded to v5.21.x, an LTS release. The LTS release is now the only supported LXD release. Users are encouraged to [migrate to Incus](https://linuxcontainers.org/incus/docs/main/howto/server_migrate_lxd/) for better support on NixOS.
