-- Cinnamon has been updated to 6.4.
+- Cinnamon has been updated to 6.4, please check the [upstream announcement](https://www.linuxmint.com/rel_xia_whatsnew.php) for more details.
+  - Following [changes in Mint 22](https://github.com/linuxmint/mintupgrade/commit/f239cde908288b8c250f938e7311c7ffbc16bd59) we are no longer overriding Qt application styles. You can still restore the previous default with `qt.style = "gtk2"` and `qt.platformTheme = "gtk2"`.
 
 - `networking.wireguard` now has an optional networkd backend. It is enabled by default when `networking.useNetworkd` is enabled, and it can be enabled alongside scripted networking with `networking.wireguard.useNetworkd`. Some `networking.wireguard` options have slightly different behavior with the networkd and script-based backends, documented in each option. Before upgrading, make sure the `privateKeyFile` and `presharedKeyFile` paths are readable by the `systemd-network` user if using the networkd backend.
