- 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.
- 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.
- 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
-`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`.
-`idris2` now requires `--package` when using packages `contrib` and `network`, while previously these idris2 packages were automatically loaded.
- The options `networking.interfaces.<name>.ipv4.routes` and `networking.interfaces.<name>.ipv6.routes` are no longer ignored when using networkd instead of the default scripted network backend by setting `networking.useNetworkd` to `true`.
- MultiMC has been replaced with the fork PolyMC due to upstream developers being hostile to 3rd party package maintainers. PolyMC removes all MultiMC branding and is aimed at providing proper 3rd party packages like the one contained in Nixpkgs. This change affects the data folder where game instances and other save and configuration files are stored. Users with existing installations should rename `~/.local/share/multimc` to `~/.local/share/polymc`. The main config file's path has also moved from `~/.local/share/multimc/multimc.cfg` to `~/.local/share/polymc/polymc.cfg`.
- The terraform 0.12 compatibility has been removed and the `terraform.withPlugins` and `terraform-providers.mkProvider` implementations simplified. Providers now need to be stored under
This breaks back-compat so it's not possible to mix-and-match with previous versions of nixpkgs. In exchange, it now becomes possible to use the providers from [nixpkgs-terraform-providers-bin](https://github.com/numtide/nixpkgs-terraform-providers-bin) directly.
-`pkgs.noto-fonts-cjk` is now deprecated in favor of `pkgs.noto-fonts-cjk-sans`
and `pkgs.noto-fonts-cjk-serif` because they each have different release
schedules. To maintain compatibility with prior releases of Nixpkgs,
`pkgs.noto-fonts-cjk` is currently an alias of `pkgs.noto-fonts-cjk-sans` and
doesn't include serif fonts.
- The interface that allows activation scripts to restart units has been reworked. Restarting and reloading is now done by a single file `/run/nixos/activation-restart-list` that honors `restartIfChanged` and `reloadIfChanged` of the units.
- The `services.bookstack.cacheDir` option has been removed, since the
cache directory is now handled by systemd.
- The `services.bookstack.extraConfig` option has been replaced by
-`lib.assertMsg` and `lib.assertOneOf` no longer return `false` if the passed condition is `false`, `throw`ing the given error message instead (which makes the resulting error message less cluttered). This will not impact the behaviour of code using these functions as intended, namely as top-level wrapper for `assert` conditions.

- The `writers.writePyPy2`/`writers.writePyPy3` and corresponding `writers.writePyPy2Bin`/`writers.writePyPy3Bin` convenience functions to create executable Python 2/3 scripts using the PyPy interpreter were added.
- The `influxdb2` package was split into `influxdb2-server` and
`influxdb2-cli`, matching the split that took place upstream. A
combined `influxdb2` package is still provided in this release for
backwards compatibilty, but will be removed at a later date.
- The `services.unifi.openPorts` option default value of `true` is now deprecated and will be changed to `false` in 22.11.
Configurations using this default will print a warning when rebuilt.
- MariaDB is now offered in several versions, not just the newest one.
So if you have a need for running MariaDB 10.4 for example, you can now just set `services.mysql.package = pkgs.mariadb_104;`.
In general, it is recommended to run the newest version, to get the newest features, while sticking with an LTS version will most likely provide a more stable experience.
Sometimes software is also incompatible with the newest version of MariaDB.
- The `services.stubby` module was converted to a [settings-style](https://github.com/NixOS/rfcs/blob/master/rfcs/0042-config-option.md) configuration.
- The option `services.thelounge.plugins` has been added to allow installing plugins for The Lounge. Plugins can be found in `pkgs.theLoungePlugins.plugins` and `pkgs.theLoungePlugins.themes`.
- The `firmwareLinuxNonfree` package has been renamed to `linux-firmware`.
-`services.mattermost.plugins` has been added to allow the declarative installation of Mattermost plugins.
Plugins are automatically repackaged using autoPatchelf.
- The `zrepl` package has been updated from 0.4.0 to 0.5:
* The RPC protocol version was bumped; all zrepl daemons in a setup must be updated and restarted before replication can resume.
* A bug involving encrypt-on-receive has been fixed. Read the [zrepl documentation](https://zrepl.github.io/configuration/sendrecvoptions.html#job-recv-options-placeholder) and check the output of `zfs get -r encryption,zrepl:placeholder PATH_TO_ROOTFS` on the receiver.
- Renamed option `services.openssh.challengeResponseAuthentication` to `services.openssh.kbdInteractiveAuthentication`.
Reason is that the old name has been deprecated upstream.
Using the old option name will still work, but produce a warning.
