<a name="relnotes_license"></a>License Change</h3></div></div></div>
<p>
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).
</p>
<p>
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.
</p>
<p>
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.
</p>
<p>
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 <a class="link" href="https://www.isc.org/mission/contact/" target="_top">
https://www.isc.org/mission/contact/</a>.

<p>
As of BIND 9.11.2, Windows XP and Windows 2003 are no longer supported
platforms for BIND; "XP" binaries are no longer available for download
from ISC.

There was a long-existing flaw in the documentation for
<span class="command"><strong>ms-self</strong></span>, <span class="command"><strong>krb5-self</strong></span>,
<span class="command"><strong>ms-subdomain</strong></span>, and <span class="command"><strong>krb5-subdomain</strong></span>
rules in <span class="command"><strong>update-policy</strong></span> statements. Though
the policies worked as intended, operators who configured their
servers according to the misleading documentation may have
thought zone updates were more restricted than they were;
users of these rule types are advised to review the documentation
and correct their configurations if necessary. New rule types
matching the previously documented behavior will be introduced
in a future maintenance release. [GL !708]

<li class="listitem">

<span class="command"><strong>named</strong></span> could crash during recursive processing

in use. This flaw is disclosed in CVE-2018-5740. [GL #387]
