- The `wafHook` hook now honors `NIX_BUILD_CORES` when `enableParallelBuilding` is not set explicitly. Packages can restore the old behaviour by setting `enableParallelBuilding=false`.
- `pkgs.claws-mail-gtk2`, representing Claws Mail's older release version three, was removed in order to get rid of Python 2.
Please switch to `claws-mail`, which is Claws Mail's latest release based on GTK+3 and Python 3.
- The `writers.writePython2` and corresponding `writers.writePython2Bin` convenience functions to create executable Python 2 scripts in the store were removed in preparation of removal of the Python 2 interpreter.
Scripts have to be converted to Python 3 for use with `writers.writePython3` or `writers.writePyPy2` needs to be used.
- `buildGoModule` was updated to use `go_1_17`, third party derivations that specify >= go 1.17 in the main `go.mod` will need to regenerate their `vendorSha256` hash.
- The `gnome-passwordsafe` package updated to [version 6.x](https://gitlab.gnome.org/World/secrets/-/tags/6.0) and renamed to `gnome-secrets`.
- `services.gnome.experimental-features.realtime-scheduling` option has been removed, as GNOME Shell now [uses rtkit](https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2060). Use `security.rtkit.enable = true;` instead. As before, you will need to have it enabled using GSettings.
- `services.telepathy` will no longer be enabled by default for GNOME desktops, one should enable it in their configs if using Empathy or Polari.
- If you previously used `/etc/docker/daemon.json`, you need to incorporate the changes into the new option `virtualisation.docker.daemon.settings`.
- Ntopng (`services.ntopng`) is updated to 5.2.1 and uses a separate Redis instance if `system.stateVersion` is at least `22.05`. Existing setups shouldn't be affected.
- The backward compatibility in `services.wordpress` to configure sites with
the old interface has been removed. Please use `services.wordpress.sites`
instead.
- The backward compatibility in `services.dokuwiki` to configure sites with the
old interface has been removed. Please use `services.dokuwiki.sites` instead.
- opensmtpd-extras is no longer build with python2 scripting support due to python2 deprecation in nixpkgs
- `services.miniflux.adminCredentialFiles` is now required, instead of defaulting to `admin` and `password`.
- The `taskserver` module no longer implicitly opens ports in the firewall
configuration. This is now controlled through the option
`services.taskserver.openFirewall`.
- The `autorestic` package has been upgraded from 1.3.0 to 1.5.0 which introduces breaking changes in config file, check [their migration guide](https://autorestic.vercel.app/migration/1.4_1.5) for more details.
- `teleport` has been upgraded to major version 9. Please see upstream [upgrade instructions](https://goteleport.com/docs/setup/operations/upgrading/) and [release notes](https://goteleport.com/docs/changelog/#900).
- For `pkgs.python3.pkgs.ipython`, its direct dependency `pkgs.python3.pkgs.matplotlib-inline`
(which is really an adapter to integrate matplotlib in ipython if it is installed) does
not depend on `pkgs.python3.pkgs.matplotlib` anymore.
This is closer to a non-Nix install of ipython.
This has the added benefit to reduce the closure size of `ipython` from ~400MB to ~160MB
(including ~100MB for python itself).
- `documentation.man` has been refactored to support choosing a man implementation other than GNU's `man-db`. For this, `documentation.man.manualPages` has been renamed to `documentation.man.man-db.manualPages`. If you want to use the new alternative man implementation `mandoc`, add `documentation.man = { enable = true; man-db.enable = false; mandoc.enable = true; }` to your configuration.
- Normal users (with `isNormalUser = true`) which have non-empty `subUidRanges` or `subGidRanges` set no longer have additional implicit ranges allocated. To enable automatic allocation back set `autoSubUidGidRange = true`.
