Cyrus IMAP 3.0.0 Release Notes
====================================
Download from GitHub:
* https://github.com/cyrusimap/cyrus-imapd/releases/download/cyrus-imapd-3.0.0/cyrus-imapd-3.0.0.tar.gz
* https://github.com/cyrusimap/cyrus-imapd/releases/download/cyrus-imapd-3.0.0/cyrus-imapd-3.0.0.tar.gz.sig
.. _relnotes-3.0.0-changes:
Major changes since the 2.5.x series
====================================
* The source repository has moved to :ref:`GitHub <github-guide>`, Bugzilla and Phabricator
have been deprecated. Their issue lists are being imported into GitHub.
* Support added for FastMail-style conversations (threaded messages).
(See the ``conversations`` options in :ref:`imapd.conf <imap-reference-manpages-configs-imapd.conf>`)
* Optional Xapian_ integration for faster and shinier search. Note that this requires custom
patches to Xapian, in this release. (See the ``search_engine`` option in
:ref:`imapd.conf <imap-reference-manpages-configs-imapd.conf>`, and ``doc/README.xapian`` in the
source distribution.) Compiling Xapian support requires gcc 4.9 or later.
* Archive support has arrived! Requires addition of an archive partition. (See ``archive_*``
options in :ref:`imapd.conf <imap-reference-manpages-configs-imapd.conf>`)
* Basic JMAP_ support. (See ``httpmodules`` in
:ref:`imapd.conf <imap-reference-manpages-configs-imapd.conf>`)
* ClamAV_ integration for AntiVirus support is now working again.
* Dropped support for Berkeley DB.
* The handling of configure options has changed, dropping support for
``--with-cyrus-prefix`` and ``--with-service-path`` in favour of the more conventional
``--prefix``, ``--bindir``, ``--sbindir``, and ``--libexecdir``.
* Binaries executed by the :ref:`master(8) <imap-reference-manpages-systemcommands-master>`
service process are now installed to ``--libexecdir``. Other binaries are installed to
``--bindir`` and/or ``--sbindir``.
The ``make installbinsymlinks`` target can be used to set up symlinks to everything in
``--bindir``, if you need that in your environment.
* Added support for replicating mailboxes/users to a particular partition. ``sync_client``
now accepts a ``-p`` option.
* The ``defaultdomain`` setting in :ref:`imapd.conf <imap-reference-manpages-configs-imapd.conf>`
now defaults to "internal" (was: NULL)
* Added experimental backup service. See Cyrus Backups
* Support for Apple's Push service (XAPPLEPUSH). See :ref:`Cyrus Eventsource <cyrus-eventsource>`
* Sieve now supports special use folders. See :ref:`Cyrus Sieve <cyrus-sieve-specialuse>`
* Sieve now supports the following :ref:`extensions <cyrus-sieve-extensions>`:
* :rfc:`5490` Checking Mailbox Status and Accessing Mailbox Metadata
* :rfc:`5229` Variables
* Sieve bytecode is now automatically recompiled when it is detected to be missing or out of date
* New numeric header available for sorting: X-Spam-Score
* Added IMIP notification support to :ref:`notifyd(8) <imap-reference-manpages-systemcommands-notifyd>`.
See ``imipnotifier`` in :ref:`imapd.conf <imap-reference-manpages-configs-imapd.conf>`
* Optimised CRC32 implementation
* Added support for reverse ACLs, enabling faster LIST response. See ``reverseacls`` in
:ref:`imapd.conf <imap-reference-manpages-configs-imapd.conf>`
* Added cross-domain sharing support. See ``crossdomains`` and ``crossdomains_onlyother``
in :ref:`imapd.conf <imap-reference-manpages-configs-imapd.conf>`
* Added experimental object storage for mail data, with preliminary support for OpenIO and
Caringo backends. See configure.ac ``--enable-objectstore``, and the ``object_storage_*``,
``openio_*`` and ``caringo_*`` options in
:ref:`imapd.conf <imap-reference-manpages-configs-imapd.conf>`.
* Configurable POP3 UIDL format for compatibility with other mail servers. Supports
Courier Mail Server and Dovecot formats, in addition to Cyrus formats. See ``uidl_format``
in :ref:`imapd.conf <imap-reference-manpages-configs-imapd.conf>`
* Under ``delete_mode: delayed``, only the 20 most recently deleted mailboxes are kept
for any given name.
* 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 ``sphinx-build``, and the perl module
``Pod::POM::View::Restructured``. The top level Makefile now has ``man`` and ``doc`` targets
for building these.
* Added support for OpenSSL 1.1.0.
* Replication now supports incremental partial updates, so massive updates (such as
mail imports) won't stall replication for other users. See ``sync_batchsize`` in
:ref:`imapd.conf <imap-reference-manpages-configs-imapd.conf>`
* The mailbox cache minor version has been incremented to store a GUID for each body part.
Updates to default configuration
================================
* ``unixhierarchysep`` (``/``) is now ``on`` by default (instead of netnews style ``.``)
* ``altnamespace`` is now ``on`` by default (was ``off``)
* ``virtdomains`` is actually **still** ``off`` by default. (Previously we stated it was
now defaulting to ``userid``: this was an error. )
Significant bugfixes
====================
* Lots of fixes to caldav and carddav.
Includes the addition of a new daemon (calalarmd) which periodically processes a global
database containing the "next" alarm for each item, and sends the relevant mboxevents.
(See configure.ac ``--with-calalarmd``)
* Replication reliability fixes.
* Improved ``LIST-EXTENDED``: more imap tests now succeed.
* Extensive cleanup of mailbox name handling
* ``master`` now requests a sane maximum number of open file descriptors, and only
complains if this isn't allowed.
* Fixes to compiling on Solaris (thanks Jens Erat, Marty Lee)
* Improved handling of mailbox renames during replication
