# 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`.
|
||
|
|
|
||
|
|
- PHP now defaults to PHP 8.1, updated from 8.0.

|
|
## 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.
|
||
|
|
|
||
|
|
- 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)`.
|
||
|
|
|
||
|
|
- PHP 7.4 is no longer supported due to upstream not supporting this
|
||
|
|
version for the entire lifecycle of the 22.11 release.
|
||
|
|
|
||
|
|
- (Neo)Vim can not be configured with `configure.pathogen` anymore to reduce maintainance burden.
|
||
|
|
Use `configure.packages` instead.

|
## Other Notable Changes {#sec-release-22.11-notable-changes}
|
||
|
|
|
||
|
|
- A new module was added for the Saleae Logic device family, providing the options `hardware.saleae-logic.enable` and `hardware.saleae-logic.package`.
|
||
|
|
|
||
|
|
- 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.
|
||
|
|
|
||
|
|
- 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.
