      <para>
        <literal>systemd-journal2gelf</literal> no longer parses json and expects the receiving system to handle it. How to achieve this with Graylog is described in this <link xlink:href="https://github.com/parse-nl/SystemdJournal2Gelf/issues/10">GitHub issue</link>.

    <para>
     If the <varname>services.dbus</varname> module is enabled, then
     the user D-Bus session is now always socket activated. The
     associated options <varname>services.dbus.socketActivated</varname>
     and <varname>services.xserver.startDbusSession</varname> have
     therefore been removed and you will receive a warning if
     they are present in your configuration. This change makes the
     user D-Bus session available also for non-graphical logins.

    <para>
     The <varname>networking.wireless.iwd</varname> module now installs
     the upstream-provided 80-iwd.link file, which sets the NamePolicy=
     for all wlan devices to "keep kernel", to avoid race conditions
     between iwd and networkd. If you don't want this, you can set
     <literal>systemd.network.links."80-iwd" = lib.mkForce {}</literal>.

     <para>
       <literal>rubyMinimal</literal> was removed due to being unused and
       unusable. The default ruby interpreter includes JIT support, which makes
       it reference it's compiler. Since JIT support is probably needed by some
       Gems, it was decided to enable this feature with all cc references by
       default, and allow to build a Ruby derivation without references to cc,
       by setting <literal>jitSupport = false;</literal> in an overlay. See
       <link xlink:href="https://github.com/NixOS/nixpkgs/pull/90151">#90151</link>
       for more info.

       Setting <option>services.openssh.authorizedKeysFiles</option> now also affects which keys <option>security.pam.enableSSHAgentAuth</option> will use.

       WARNING: If you are using these options in combination do make sure that any key paths you use are present in <option>services.openssh.authorizedKeysFiles</option>!

     The option <option>fonts.enableFontDir</option> has been renamed to

     has also been changed to <literal>/run/current-system/sw/share/X11/fonts</literal>,

      The socket for the <literal>pdns-recursor</literal> module was moved from <literal>/var/lib/pdns-recursor</literal>

      Paperwork was updated to version 2. The on-disk format slightly changed,
      and it is not possible to downgrade from Paperwork 2 back to Paperwork
      1.3. Back your documents up before upgrading. See <link xlink:href="https://forum.openpaper.work/t/paperwork-2-0/112/5">this thread</link> for more details.

      PowerDNS has been updated from <literal>4.2.x</literal> to <literal>4.3.x</literal>. Please
      be sure to review the <link xlink:href="https://doc.powerdns.com/authoritative/upgrading.html#x-to-4-3-0">Upgrade Notes</link>
      provided by upstream before upgrading. Worth specifically noting is that the service now runs
      entirely as a dedicated <literal>pdns</literal> user, instead of starting as <literal>root</literal>
      and dropping privileges, as well as the default <literal>socket-dir</literal> location changing from
      <literal>/var/lib/powerdns</literal> to <literal>/run/pdns</literal>.

       xfsprogs was update from 4.19 to 5.10. It now enables reflink support by default on filesystem creation.
       Support for reflinks was added with an experimental status to kernel 4.9 and deemed stable in kernel 4.16.
       If you want to be able to mount XFS filesystems created with this release of xfsprogs on kernel releases older than those, you need to format them
       with <literal>mkfs.xfs -m reflink=0</literal>.
