- GNOME has been upgraded to 42. Please take a look at their [Release Notes](https://release.gnome.org/42/) for details. Notably, it replaces gedit with GNOME Text Editor, GNOME Terminal with GNOME Console (formerly King’s Cross), and GNOME Screenshot with a tool built into the Shell.
- `stdenv.mkDerivation` now supports a self-referencing `finalAttrs:` parameter
containing the final `mkDerivation` arguments including overrides.
`drv.overrideAttrs` now supports two parameters `finalAttrs: previousAttrs:`.
This allows packaging configuration to be overridden in a consistent manner by
providing an alternative to `rec {}` syntax.
Additionally, `passthru` can now reference `finalAttrs.public` containing
the final package, including attributes such as the output paths and
`overrideAttrs`.
New language integrations can be simplified by overriding a "prototype"
package containing the language-specific logic. This removes the need for a
extra layer of overriding for the "generic builder" arguments, thus removing a
usability problem and source of error.

- Mattermost has been updated to extended support release 6.3, as the previously packaged extended support release 5.37 is [reaching its end of life](https://docs.mattermost.com/upgrade/extended-support-release.html).
