<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>
