<literal>pkgs.ghc</literal> now refers to
<literal>pkgs.targetPackages.haskellPackages.ghc</literal>.
This <emphasis>only</emphasis> makes a difference if you are
cross-compiling and will ensure that
<literal>pkgs.ghc</literal> always runs on the host platform
and compiles for the target platform (similar to
<literal>pkgs.gcc</literal> for example).
<literal>haskellPackages.ghc</literal> still behaves as
before, running on the build platform and compiling for the
host platform (similar to <literal>stdenv.cc</literal>). This
means you don’t have to adjust your derivations if you use
<literal>haskellPackages.callPackage</literal>, but when using
<literal>pkgs.callPackage</literal> and taking
<literal>ghc</literal> as an input, you should now use
<literal>buildPackages.ghc</literal> instead to ensure cross
compilation keeps working (or switch to

MultiMC has been replaced with the fork PolyMC due to upstream
developers being hostile to 3rd party package maintainers.
PolyMC removes all MultiMC branding and is aimed at providing
proper 3rd party packages like the one contained in Nixpkgs.
This change affects the data folder where game instances and
other save and configuration files are stored. Users with
existing installations should rename
<literal>~/.local/share/multimc</literal> to
<literal>~/.local/share/polymc</literal>. The main config

In general, it is recommended to run the newest version, to
