# 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`.

## 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*.
