Due to lack of maintenance. It is not compatible with the default Python version (due to the tornado 5) dependency, and doesn't look like it will be any time soon.

# Release 22.11 (“Raccoon”, 2022.11/??) {#sec-release-22.11}
|
|
|
|
Support is planned until the end of June 2023, handing over to 23.05.
|
|
|
|
## Highlights {#sec-release-22.11-highlights}
|
|
|
|
In addition to numerous new and upgraded packages, this release has the following highlights:
|
|
|
|
- During cross-compilation, tests are now executed if the test suite can be executed
|
|
by the build platform. This is the case when doing “native” cross-compilation
|
|
where the build and host platforms are largely the same, but the nixpkgs' cross
|
|
compilation infrastructure is used, e.g. `pkgsStatic` and `pkgsLLVM`. Another
|
|
possibility is that the build platform is a superset of the host platform, e.g. when
|
|
cross-compiling from `x86_64-unknown-linux` to `i686-unknown-linux`.
|
|
The predicate gating test suite execution is the newly added `canExecute`
|
|
predicate: You can e.g. check if `stdenv.buildPlatform` can execute binaries
|
|
built for `stdenv.hostPlatform` (i.e. produced by `stdenv.cc`) by evaluating
|
|
`stdenv.buildPlatform.canExecute stdenv.hostPlatform`.
|
|
|
|
- The `nixpkgs.hostPlatform` and `nixpkgs.buildPlatform` options have been added.
|
|
These cover and override the `nixpkgs.{system,localSystem,crossSystem}` options.
|
|
|
|
- `hostPlatform` is the platform or "`system`" string of the NixOS system
|
|
described by the configuration.
|
|
- `buildPlatform` is the platform that is responsible for building the NixOS
|
|
configuration. It defaults to the `hostPlatform`, for a non-cross
|
|
build configuration. To cross compile, set `buildPlatform` to a different
|
|
value.
|
|
|
|
The new options convey the same information, but with fewer options, and
|
|
following the Nixpkgs terminology.
|
|
|
|
The existing options `nixpkgs.{system,localSystem,crossSystem}` have not
|
|
been formally deprecated, to allow for evaluation of the change and to allow
|
|
for a transition period so that in time the ecosystem can switch without
|
|
breaking compatibility with any supported NixOS release.
|
|
|
|
- `nixos-generate-config` now generates configurations that can be built in pure
|
|
mode. This is achieved by setting the new `nixpkgs.hostPlatform` option.
|
|
|
|
You may have to unset the `system` parameter in `lib.nixosSystem`, or similarly
|
|
remove definitions of the `nixpkgs.{system,localSystem,crossSystem}` options.
|
|
|
|
Alternatively, you can remove the `hostPlatform` line and use NixOS like you
|
|
would in NixOS 22.05 and earlier.
|
|
|
|
- PHP now defaults to PHP 8.1, updated from 8.0.
|
|
|
|
- `hardware.nvidia` has a new option `open` that can be used to opt in the opensource version of NVIDIA kernel driver. Note that the driver's support for GeForce and Workstation GPUs is still alpha quality, see [NVIDIA Releases Open-Source GPU Kernel Modules](https://developer.nvidia.com/blog/nvidia-releases-open-source-gpu-kernel-modules/) for the official announcement.

|
|
|
|
## Backward Incompatibilities {#sec-release-22.11-incompatibilities}
|
|
|
|
- The `isCompatible` predicate checking CPU compatibility is no longer exposed
|
|
by the platform sets generated using `lib.systems.elaborate`. In most cases
|
|
you will want to use the new `canExecute` predicate instead which also
|
|
considers the kernel / syscall interface. It is briefly described in the
|
|
release's [highlights section](#sec-release-22.11-highlights).
|
|
`lib.systems.parse.isCompatible` still exists, but has changed semantically:
|
|
Architectures with differing endianness modes are *no longer considered compatible*.
|
|
|
|
- `ngrok` has been upgraded from 2.3.40 to 3.0.4. Please see [the upgrade guide](https://ngrok.com/docs/guides/upgrade-v2-v3)
|
|
and [changelog](https://ngrok.com/docs/ngrok-agent/changelog). Notably, breaking changes are that the config file format has
|
|
changed and support for single hypen arguments was dropped.
|
|
|
|
- `i18n.supportedLocales` is now by default only generated with the locales set in `i18n.defaultLocale` and `i18n.extraLocaleSettings`.
|
|
This got partially copied over from the minimal profile and reduces the final system size by up to 200MB.
|
|
If you require all locales installed set the option to ``[ "all" ]``.
|
|
|
|
- The `isPowerPC` predicate, found on `platform` attrsets (`hostPlatform`, `buildPlatform`, `targetPlatform`, etc) has been removed in order to reduce confusion. The predicate was was defined such that it matches only the 32-bit big-endian members of the POWER/PowerPC family, despite having a name which would imply a broader set of systems. If you were using this predicate, you can replace `foo.isPowerPC` with `(with foo; isPower && is32bit && isBigEndian)`.
|
|
|
|
- `bsp-layout` no longer uses the command `cycle` to switch to other window layouts, as it got replaced by the commands `previous` and `next`.
|
|
|
|
- The Barco ClickShare driver/client package `pkgs.clickshare-csc1` and the option `programs.clickshare-csc1.enable` have been removed,
|
|
as it requires `qt4`, which reached its end-of-life 2015 and will no longer be supported by nixpkgs.
|
|
[According to Barco](https://www.barco.com/de/support/knowledge-base/4380-can-i-use-linux-os-with-clickshare-base-units) many of their base unit models can be used with Google Chrome and the Google Cast extension.
|
|
|
|
- PHP 7.4 is no longer supported due to upstream not supporting this
|
|
version for the entire lifecycle of the 22.11 release.
|
|
|
|
- riak package removed along with `services.riak` module, due to lack of maintainer to update the package.
|
|
|
|
- The `services.graphite.beacon` NixOS option, and the `python3.pkgs.graphite_beacon`
|
|
package, has been removed due to lack of upstream maintenance.
|
|
|
|
- (Neo)Vim can not be configured with `configure.pathogen` anymore to reduce maintainance burden.
|
|
Use `configure.packages` instead.
|
|
|
|
- `k3s` no longer supports docker as runtime due to upstream dropping support.

## Other Notable Changes {#sec-release-22.11-notable-changes}
|
|
|
|
- The `xplr` package has been updated from 0.18.0 to 0.19.0, which brings some breaking changes. See the [upstream release notes](https://github.com/sayanarijit/xplr/releases/tag/v0.19.0) for more details.
|
|
|
|
- A new module was added for the Saleae Logic device family, providing the options `hardware.saleae-logic.enable` and `hardware.saleae-logic.package`.
|
|
|
|
- The Redis module now disables RDB persistence when `services.redis.servers.<name>.save = []` instead of using the Redis default.
|
|
|
|
- Matrix Synapse now requires entries in the `state_group_edges` table to be unique, in order to prevent accidentally introducing duplicate information (for example, because a database backup was restored multiple times). If your Synapse database already has duplicate rows in this table, this could fail with an error and require manual remediation.
|
|
|
|
- `dockerTools.buildImage` deprecates the misunderstood `contents` parameter, in favor of `copyToRoot`.
|
|
Use `copyToRoot = buildEnv { ... };` or similar if you intend to add packages to `/bin`.
|
|
|
|
- memtest86+ was updated from 5.00-coreboot-002 to 6.00-beta2. It is now the upstream version from https://www.memtest.org/, as coreboot's fork is no longer available.
|
|
|
|
- Add udev rules for the Teensy family of microcontrollers.
|
|
|
|
- There is a new module for the `thunar` program (the Xfce file manager), which depends on the `xfconf` dbus service, and also has a dbus service and a systemd unit. The option `services.xserver.desktopManager.xfce.thunarPlugins` has been renamed to `programs.thunar.plugins`, and in a future release it may be removed.
|
|
|
|
- There is a new module for the `xfconf` program (the Xfce configuration storage system), which has a dbus service.
