BIND has multiple methods for managing DNSSEC trust anchors, with somewhat different behaviors. If the root key is configured using the <span class="command"><strong>managed-keys</strong></span> statement, or if the pre-configured root key is enabled by using <span class="command"><strong>dnssec-validation auto</strong></span>, then BIND can keep keys up to date automatically. Servers configured in this way should have begun the process of rolling to the new key when it was published in the root zone in July 2017. However, keys configured using the <span class="command"><strong>trusted-keys</strong></span> statement are not automatically maintained. If your server is performing DNSSEC validation and is configured using <span class="command"><strong>trusted-keys</strong></span>, you are advised to change your configuration before the root zone begins signing with the new KSK. This is currently scheduled for October 11, 2017. </p> <p> This release includes an updated version of the <code class="filename">bind.keys</code> file containing the new root key. This file can also be downloaded from <a class="link" href="https://www.isc.org/bind-keys" target="_top"> https://www.isc.org/bind-keys </a>. </p> </div> <div class="section"> <div class="titlepage"><div><div><h3 class="title"> <a name="win_support"></a>Windows XP No Longer Supported</h3></div></div></div> <p> As of BIND 9.10.6, Windows XP is no longer a supported platform for BIND, and Windows XP binaries are no longer available for download from ISC. </p> </div> <div class="section"> <div class="titlepage"><div><div><h3 class="title"> <a name="relnotes_security"></a>Security Fixes</h3></div></div></div> <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> <li class="listitem"> <p> Addresses could be referenced after being freed during resolver processing, causing an assertion failure.
