  <title>Backward Incompatibilities</title>

  <para>
   When upgrading from a previous release, please be aware of the following
   incompatible changes:
  </para>

  <itemizedlist>
   <listitem>
    <para>
     <literal>lib.strict</literal> is removed. Use
     <literal>builtins.seq</literal> instead.
    </para>
   </listitem>
   <listitem>
    <para>
     The <literal>clementine</literal> package points now to the free
     derivation. <literal>clementineFree</literal> is removed now and
     <literal>clementineUnfree</literal> points to the package which is bundled
     with the unfree <literal>libspotify</literal> package.
    </para>
   </listitem>
   <listitem>
    <para>
     The <literal>netcat</literal> package is now taken directly from OpenBSD's
     <literal>libressl</literal>, instead of relying on Debian's fork. The new
     version should be very close to the old version, but there are some minor
     differences. Importantly, flags like -b, -q, -C, and -Z are no longer
     accepted by the nc command.
    </para>
   </listitem>
   <listitem>
    <para>
     The <varname>services.docker-registry.extraConfig</varname> object doesn't contain
     environment variables anymore. Instead it needs to provide an object structure
     that can be mapped onto the YAML configuration defined in <link xlink:href="https://github.com/docker/distribution/blob/v2.6.2/docs/configuration.md">the <varname>docker/distribution</varname> docs</link>.
