<itemizedlist>

  <listitem>
    <para>Shell aliases for systemd sub-commands
    <link xlink:href="https://github.com/NixOS/nixpkgs/pull/15598">were dropped</link>:

    <command>restart</command>, <command>status</command>.</para>
  </listitem>

  <listitem>
    <para>Redis now binds to 127.0.0.1 only instead of listening to all network interfaces. This is the default
    behavior of Redis 3.2</para>
  </listitem>

  <listitem>
    <para>Gitlab's maintainence script gitlab-runner was removed and split up into the more clearer
      gitlab-run and gitlab-rake scripts because gitlab-runner is a component of Gitlab CI.</para>
  </listitem>

  <listitem>
    <para><literal>services.xserver.libinput.accelProfile</literal> default
    changed from <literal>flat</literal> to <literal>adaptive</literal>,
    as per <link xlink:href="https://wayland.freedesktop.org/libinput/doc/latest/group__config.html#gad63796972347f318b180e322e35cee79">
    official documentation</link>.</para>
  </listitem>

  <listitem>
    <para><literal>fonts.fontconfig.ultimate.rendering</literal> was removed
    because our presets were obsolete for some time. New presets are hardcoded
    into freetype; one selects a preset via <literal>fonts.fontconfig.ultimate.preset</literal>.
    You can customize those presets via ordinary environment variables, using
    <literal>environment.variables</literal>.</para>

<para>Other notable improvements:</para>

<itemizedlist>

  <listitem><para>Revamped grsecurity/PaX support.  There is now only a single
  general-purpose distribution kernel and the configuration interface has been
  streamlined.  Desktop users should be able to simply set
  <programlisting>security.grsecurity.enable = true</programlisting> to get
  a reasonably secure system without having to sacrifice too much
  functionality.  See <xref linkend="sec-grsecurity" /> for documentation
  </para></listitem>
