 - 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"`.
 
+- Xfce has been updated to 4.20, please check the [upstream feature tour](https://www.xfce.org/about/tour420) for more details.
+  - Wayland session is still [experimental](https://wiki.xfce.org/releng/wayland_roadmap) and requires opt-in using `enableWaylandSession` option.
+  - Overriding Wayland compositor is possible using `enableWaylandSession` option, but you might need to take care [`xfce4-session`](https://gitlab.xfce.org/xfce/xfce4-session/-/merge_requests/49), [`dbus-update-activation-environment`](https://github.com/labwc/labwc/blob/eaf11face68ee1f1bcc7ce1498304ca8c108c8ba/src/config/session.c#L234) and [`systemctl --user import-environment`](https://github.com/labwc/labwc/blob/eaf11face68ee1f1bcc7ce1498304ca8c108c8ba/src/config/session.c#L239) on startup.
+  - For new Xfce installations, default panel layout has [changed](https://gitlab.xfce.org/xfce/xfce4-panel/-/merge_requests/158/diffs) to not include external panel plugins by default. You can still add them yourself using the "Panel Preferences" dialog.
+
 - `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.
 
 - `services.avahi.ipv6` now defaults to true.
