<para>
<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
<literal>haskellPackages.callPackage</literal>).

For <literal>pkgs.python3.pkgs.ipython</literal>, its direct
dependency
<literal>pkgs.python3.pkgs.matplotlib-inline</literal> (which
is really an adapter to integrate matplotlib in ipython if it
is installed) does not depend on
<literal>pkgs.python3.pkgs.matplotlib</literal> anymore. This
is closer to a non-Nix install of ipython. This has the added
benefit to reduce the closure size of
<literal>ipython</literal> from ~400MB to ~160MB (including
~100MB for python itself).

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
file’s path has also moved from
<literal>~/.local/share/multimc/multimc.cfg</literal> to
<literal>~/.local/share/polymc/polymc.cfg</literal>.

<literal>pkgs.noto-fonts-cjk</literal> is now deprecated in
favor of <literal>pkgs.noto-fonts-cjk-sans</literal> and
<literal>pkgs.noto-fonts-cjk-serif</literal> because they each
have different release schedules. To maintain compatibility
with prior releases of Nixpkgs,
<literal>pkgs.noto-fonts-cjk</literal> is currently an alias
of <literal>pkgs.noto-fonts-cjk-sans</literal> and doesn’t
include serif fonts.

<para>
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."".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.""</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.${serverName}</literal>
are only accessible by default to the members of the Unix
group <literal>redis-${serverName}</literal> through the Unix
socket <literal>/run/redis-${serverName}/redis.sock</literal>.

The option
<link linkend="opt-virtualisation.vmVariant">virtualisation.vmVariant</link>

<para>
The <literal>config.system.build.vm</literal> attribute now
always exists and defaults to the value from
<literal>vmVariant</literal>. Configurations that import the
<literal>virtualisation/qemu-vm.nix</literal> module
themselves will override this value, such that
<literal>vmVariant</literal> is not used.
