<ul>
<li><p>The source repository has moved to <a class="reference internal" href="../../../../developer/github-guide.html#github-guide"><span class="std std-ref">GitHub</span></a>, Bugzilla and Phabricator
have been deprecated. Their issue lists are being imported into GitHub.</p></li>
<li><p>Support added for FastMail-style conversations (threaded messages).
(See the <code class="docutils literal notranslate"><span class="pre">conversations</span></code> options in <a class="reference internal" href="../../../../reference/manpages/configs/imapd.conf.html#imap-reference-manpages-configs-imapd-conf"><span class="std std-ref">imapd.conf</span></a>)</p></li>
<li><p>Optional <a class="reference external" href="https://xapian.org">Xapian</a> integration for faster and shinier search. Note that this requires custom
patches to Xapian, in this release. (See the <code class="docutils literal notranslate"><span class="pre">search_engine</span></code> option in
<a class="reference internal" href="../../../../reference/manpages/configs/imapd.conf.html#imap-reference-manpages-configs-imapd-conf"><span class="std std-ref">imapd.conf</span></a>, and <code class="docutils literal notranslate"><span class="pre">doc/README.xapian</span></code> in the
source distribution.) Compiling Xapian support requires gcc 4.9 or later.</p></li>
<li><p>Archive support has arrived! Requires addition of an archive partition. (See <code class="docutils literal notranslate"><span class="pre">archive_*</span></code>
options in <a class="reference internal" href="../../../../reference/manpages/configs/imapd.conf.html#imap-reference-manpages-configs-imapd-conf"><span class="std std-ref">imapd.conf</span></a>)</p></li>
<li><p>Basic <a class="reference external" href="http://jmap.io">JMAP</a> support. (See <code class="docutils literal notranslate"><span class="pre">httpmodules</span></code> in
<a class="reference internal" href="../../../../reference/manpages/configs/imapd.conf.html#imap-reference-manpages-configs-imapd-conf"><span class="std std-ref">imapd.conf</span></a>)</p></li>

<li><p>Dropped support for Berkeley DB.</p></li>
<li><p>The handling of configure options has changed, dropping support for
<code class="docutils literal notranslate"><span class="pre">--with-cyrus-prefix</span></code> and <code class="docutils literal notranslate"><span class="pre">--with-service-path</span></code> in favour of the more conventional
<code class="docutils literal notranslate"><span class="pre">--prefix</span></code>, <code class="docutils literal notranslate"><span class="pre">--bindir</span></code>, <code class="docutils literal notranslate"><span class="pre">--sbindir</span></code>, and <code class="docutils literal notranslate"><span class="pre">--libexecdir</span></code>.</p></li>

<code class="docutils literal notranslate"><span class="pre">--bindir</span></code>, if you need that in your environment.</p>
</li>
<li><p>Added support for replicating mailboxes/users to a particular partition. <code class="docutils literal notranslate"><span class="pre">sync_client</span></code>
now accepts a <code class="docutils literal notranslate"><span class="pre">-p</span></code> option.</p></li>
<li><p>The <code class="docutils literal notranslate"><span class="pre">defaultdomain</span></code> setting in <a class="reference internal" href="../../../../reference/manpages/configs/imapd.conf.html#imap-reference-manpages-configs-imapd-conf"><span class="std std-ref">imapd.conf</span></a>
now defaults to "internal" (was: NULL)</p></li>
<li><p>Added experimental backup service. See <a class="reference internal" href="../../../../reference/admin/backups.html#cyrus-backups"><span class="std std-ref">Cyrus Backups</span></a></p></li>

<li><p><span class="target" id="index-1"></span><a class="rfc reference external" href="https://datatracker.ietf.org/doc/html/rfc5229.html"><strong>RFC 5229</strong></a> Variables</p></li>
</ul>
</li>
<li><p>Sieve bytecode is now automatically recompiled when it is detected to be missing or out of date</p></li>
<li><p>New numeric header available for sorting: X-Spam-Score</p></li>
<li><p>Added IMIP notification support to <a class="reference internal" href="../../../../reference/manpages/systemcommands/notifyd.html#imap-reference-manpages-systemcommands-notifyd"><span class="std std-ref">notifyd(8)</span></a>.
See <code class="docutils literal notranslate"><span class="pre">imipnotifier</span></code> in <a class="reference internal" href="../../../../reference/manpages/configs/imapd.conf.html#imap-reference-manpages-configs-imapd-conf"><span class="std std-ref">imapd.conf</span></a></p></li>
<li><p>Optimised CRC32 implementation</p></li>
<li><p>Added support for reverse ACLs, enabling faster LIST response. See <code class="docutils literal notranslate"><span class="pre">reverseacls</span></code> in
<a class="reference internal" href="../../../../reference/manpages/configs/imapd.conf.html#imap-reference-manpages-configs-imapd-conf"><span class="std std-ref">imapd.conf</span></a></p></li>
<li><p>Added cross-domain sharing support. See <code class="docutils literal notranslate"><span class="pre">crossdomains</span></code> and <code class="docutils literal notranslate"><span class="pre">crossdomains_onlyother</span></code>
in <a class="reference internal" href="../../../../reference/manpages/configs/imapd.conf.html#imap-reference-manpages-configs-imapd-conf"><span class="std std-ref">imapd.conf</span></a></p></li>
<li><p>Added experimental object storage for mail data, with preliminary support for OpenIO and
Caringo backends. See configure.ac <code class="docutils literal notranslate"><span class="pre">--enable-objectstore</span></code>, and the <code class="docutils literal notranslate"><span class="pre">object_storage_*</span></code>,
<code class="docutils literal notranslate"><span class="pre">openio_*</span></code> and <code class="docutils literal notranslate"><span class="pre">caringo_*</span></code> options in
<a class="reference internal" href="../../../../reference/manpages/configs/imapd.conf.html#imap-reference-manpages-configs-imapd-conf"><span class="std std-ref">imapd.conf</span></a>.</p></li>
<li><p>Configurable POP3 UIDL format for compatibility with other mail servers. Supports
Courier Mail Server and Dovecot formats, in addition to Cyrus formats. See <code class="docutils literal notranslate"><span class="pre">uidl_format</span></code>
in <a class="reference internal" href="../../../../reference/manpages/configs/imapd.conf.html#imap-reference-manpages-configs-imapd-conf"><span class="std std-ref">imapd.conf</span></a></p></li>
<li><p>Under <code class="docutils literal notranslate"><span class="pre">delete_mode:</span> <span class="pre">delayed</span></code>, only the 20 most recently deleted mailboxes are kept
for any given name.</p></li>
<li><p>Documentation cleanup: we are moving toward having a single restructured text source for man
pages and html/text documentation, which are pre-generated for inclusion in release tarballs.
If you wish to rebuild these, or are building from a git clone in which they are not
pregenerated, you will need to install <code class="docutils literal notranslate"><span class="pre">sphinx-build</span></code>, and the perl module
<code class="docutils literal notranslate"><span class="pre">Pod::POM::View::Restructured</span></code>. The top level Makefile now has <code class="docutils literal notranslate"><span class="pre">man</span></code> and <code class="docutils literal notranslate"><span class="pre">doc</span></code> targets
for building these.</p></li>
<li><p>Added support for OpenSSL 1.1.0.</p></li>
<li><p>Replication now supports incremental partial updates, so massive updates (such as
mail imports) won't stall replication for other users. See <code class="docutils literal notranslate"><span class="pre">sync_batchsize</span></code> in
<a class="reference internal" href="../../../../reference/manpages/configs/imapd.conf.html#imap-reference-manpages-configs-imapd-conf"><span class="std std-ref">imapd.conf</span></a></p></li>
<li><p>The mailbox cache minor version has been incremented to store a GUID for each body part.</p></li>

<ul>
<li><p>Lots of fixes to caldav and carddav.</p>
<p>Includes the addition of a new daemon (calalarmd) which periodically processes a global

</li>

<li><p>Extensive cleanup of mailbox name handling</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">master</span></code> now requests a sane maximum number of open file descriptors, and only
