<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
compilation keeps working (or switch to
<literal>haskellPackages.callPackage</literal>).

<literal>pkgs.emacsPackages.orgPackages</literal> is removed
because org elpa is deprecated. The packages in the top level
of <literal>pkgs.emacsPackages</literal>, such as org and
org-contrib, refer to the ones in

<literal>pkgs.claws-mail-gtk2</literal>, representing Claws

release based on GTK+3 and Python 3.

The <literal>writers.writePython2</literal> and corresponding
<literal>writers.writePython2Bin</literal> convenience
functions to create executable Python 2 scripts in the store
were removed in preparation of removal of the Python 2
interpreter. Scripts have to be converted to Python 3 for use
with <literal>writers.writePython3</literal> or
<literal>writers.writePyPy2</literal> needs to be used.

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).

<literal>documentation.man</literal> has been refactored to
support choosing a man implementation other than GNUs
<literal>man-db</literal>. For this,
<literal>documentation.man.manualPages</literal> has been
renamed to
<literal>documentation.man.man-db.manualPages</literal>. If
you want to use the new alternative man implementation
<literal>mandoc</literal>, add
<literal>documentation.man = { enable = true; man-db.enable = false; mandoc.enable = true; }</literal>
to your configuration.

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

The

and corresponding
<literal>writers.writePyPy2Bin</literal>/<literal>writers.writePyPy3Bin</literal>
convenience functions to create executable Python 2/3 scripts
using the PyPy interpreter were added.

The <literal>influxdb2</literal> package was split into
<literal>influxdb2-server</literal> and
<literal>influxdb2-cli</literal>, matching the split that took
place upstream. A combined <literal>influxdb2</literal>
package is still provided in this release for backwards
compatibilty, but will be removed at a later date.

<para>
The <literal>services.unifi.openPorts</literal> option default
value of <literal>true</literal> is now deprecated and will be
changed to <literal>false</literal> in 22.11. Configurations
using this default will print a warning when rebuilt.

The option
<link linkend="opt-programs.ssh.enableAskPassword">programs.ssh.enableAskPassword</link>
was added, decoupling the setting of

usage in non-X11 environments, e.g. Wayland.
