<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 dont 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

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
files path has also moved from

This breaks back-compat so its not possible to mix-and-match

The option
<link linkend="opt-services.redis.servers">services.redis.servers</link>
was added to support per-application
<literal>redis-server</literal> which is more secure since
Redis databases are only mere key prefixes without any
configuration or ACL of their own. Backward-compatibility is
preserved by mapping old
<literal>services.redis.settings</literal> to
<literal>services.redis.servers.&quot;&quot;.settings</literal>,
but you are strongly encouraged to name each
<literal>redis-server</literal> instance after the application
using it, instead of keeping that nameless one. Except for the
nameless
<literal>services.redis.servers.&quot;&quot;</literal> still
accessible at <literal>127.0.0.1:6379</literal>, and to the
members of the Unix group <literal>redis</literal> through the
Unix socket <literal>/run/redis/redis.sock</literal>, all
other <literal>services.redis.servers.${serverName}</literal>

If you are using Wayland you can choose to use the Ozone
Wayland support in Chrome and several Electron apps by setting
the environment variable <literal>NIXOS_OZONE_WL=1</literal>
(for example via
<literal>environment.sessionVariables.NIXOS_OZONE_WL = &quot;1&quot;</literal>).
This is not enabled by default because Ozone Wayland is still
under heavy development and behavior is not always flawless.
Furthermore, not all Electron apps use the latest Electron
versions.

MariaDB is now offered in several versions, not just the
newest one. So if you have a need for running MariaDB 10.4 for
example, you can now just set
<literal>services.mysql.package = pkgs.mariadb_104;</literal>.
In general, it is recommended to run the newest version, to
get the newest features, while sticking with an LTS version
will most likely provide a more stable experience. Sometimes
software is also incompatible with the newest version of
MariaDB.
