 - The `services.mxisd` module has been removed as both [mxisd](https://github.com/kamax-matrix/mxisd) and [ma1sd](https://github.com/ma1uta/ma1sd) are not maintained any longer.
   Consequently the package `pkgs.ma1sd` has also been removed.
 
-- `ffmpeg_5` has been removed. Please use the unversioned `ffmpeg`,
-  pin a newer version, or if necessary pin `ffmpeg_4` for compatibility.
-
 - The `xdg.portal.gtkUsePortal` option has been removed, as it had been deprecated for over 2 years. Using the `GTK_USE_PORTAL` environment variable in this manner is not intended nor encouraged by the GTK developers, but can still be done manually via `environment.sessionVariables`.
 
 - The `services.trust-dns` module has been renamed to `services.hickory-dns`.

+- The default FFmpeg version is now 7, and FFmpeg 5 has been removed.
+  Please prefer using the package variants without a version suffix,
+  or pin FFmpeg 6 or 4 if necessary for compatibility.
+  Note that we keep old versions around only as required
+  to support packages in the tree,
+  and FFmpeg 4 especially should be avoided in favour of newer versions
+  as it may be removed soon.
