 - Starting with v14, `flameshot` will primarily utilise xdg-desktop-portal calls for screenshotting. This will directly affect users on X11 window managers due to the lack of a compatible portal with Screenshot feature. See [upstream changelog](https://github.com/flameshot-org/flameshot/releases/tag/v14.0.0) or [NixOS Flameshot](https://wiki.nixos.org/wiki/Flameshot) wiki page for workarounds.
 - `nim1` and respective aliases have been removed due to entering EOL; please migrate to `nim` or `nim-unwrapped` (nim 2).
 - `nim-2_0` & `nim-2_2` and respective aliases have been removed; please migrate to `nim` or `nim-unwrapped` (nim 2.2.10).
+- `domoticz` has been updated from `2024.7` to `2026.x`, breaking third party applications and scripts using the old RType calls. Review the [release notes](https://github.com/domoticz/domoticz/blob/2026.2/History.txt#L398) for more information.
 
 - `vimacs` has been removed, as it has not been maintained in 10 years and was built for an old version of vim (6.0).
