# Release 22.05 (“Quokka”, 2022.05/??) {#sec-release-22.05} In addition to numerous new and upgraded packages, this release has the following highlights: - Support is planned until the end of December 2022, handing over to 22.11. ## 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`. ## Other Notable Changes {#sec-release-22.05-notable-changes}
