Release 22.11 (“Raccoon”, 2022.11/??)

Support is planned until the end of June 2023, handing over to 23.05.

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.

appvm, Nix based app VMs. Available as virtualisation.appvm.
dragonflydb, a modern replacement for Redis and Memcached. Available as services.dragonflydb.
infnoise, a hardware True Random Number Generator dongle. Available as services.infnoise.
persistent-evdev, a daemon to add virtual proxy devices that mirror a physical input device but persist even if the underlying hardware is hot-plugged. Available as services.persistent-evdev.
expressvpn, the CLI client for ExpressVPN. Available as services.expressvpn.

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. 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 and 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.

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.
