## Highlights {#sec-release-22.05-highlights}
## New Services {#sec-release-22.05-new-services}
## Backward Incompatibilities {#sec-release-22.05-incompatibilities}
- `pkgs.ghc` now refers to `pkgs.targetPackages.haskellPackages.ghc` .
This *only* makes a difference if you are cross-compiling and will
ensure that `pkgs.ghc` always runs on the host platform and compiles
for the target platform (similar to `pkgs.gcc` for example).
`haskellPackages.ghc` still behaves as before, running on the build
platform and compiling for the host platform (similar to `stdenv.cc` ).
This means you don't have to adjust your derivations if you use
`haskellPackages.callPackage` , but when using `pkgs.callPackage` and
taking `ghc` as an input, you should now use `buildPackages.ghc`
instead to ensure cross compilation keeps working (or switch to
`haskellPackages.callPackage` ).
- `pkgs.emacsPackages.orgPackages` is removed because org elpa is deprecated.
The packages in the top level of `pkgs.emacsPackages` , such as org and
org-contrib, refer to the ones in `pkgs.emacsPackages.elpaPackages` and
`pkgs.emacsPackages.nongnuPackages` where the new versions will release.
- The `wafHook` hook now honors `NIX_BUILD_CORES` when `enableParallelBuilding` is not set explicitly. Packages can restore the old behaviour by setting `enableParallelBuilding=false` .
