<title>Release 1.8 (TBA)</title>

<itemizedlist>

  <listitem><para>Derivations can specify the new special attribute
  <varname>allowedRequisites</varname>, which has a similar meaning to
  <varname>allowedReferences</varname>. But instead of only enforcing
  to explicitly specify the immediate references, it requires the
  derivation to specify all the dependencies recursively (hence the
  name, requisites) that are used by the resulting
  output.</para></listitem>
