  <section xml:id="relnotes_license"><info><title>License Change</title></info>
    <para>
      With the release of BIND 9.11.0, ISC changed to the open
      source license for BIND from the ISC license to the Mozilla
      Public License (MPL 2.0).
    </para>
    <para>
      The MPL-2.0 license requires that if you make changes to
      licensed software (e.g. BIND) and distribute them outside
      your organization, that you publish those changes under that
      same license. It does not require that you publish or disclose
      anything other than the changes you made to our software.
    </para>
    <para>
      This requirement will not affect anyone who is using BIND, with
      or without modifications, without redistributing it, nor anyone
      redistributing it without changes. Therefore, this change will be
      without consequence for most individuals and organizations who are
      using BIND.
    </para>
    <para>
      Those unsure whether or not the license change affects their
      use of BIND, or who wish to discuss how to comply with the
      license may contact ISC at <link
