Cyrus IMAP 3.6.0-beta3 Release Notes
====================================
Download from GitHub:

.. _relnotes-3.6.0-beta3-changes:
Major changes since the 3.4 series
==================================
* All members of a newly created mailbox hierarchy will now be selectable
mailboxes. In other words, when creating mailbox user.foo.A.B.C, both
user.foo.A and user.foo.A.B will also be created as real mailboxes.
* XFER will no longer move individual mailboxes that would leave unselectable
mailboxes behind in the user heirarchy.
* Update IMAP PREVIEW extension from
:draft:`draft-ietf-extra-imap-fetch-preview-07` to :rfc:`8970`
* JMAP Blob handling updated to :draft:`draft-ietf-jmap-blob-04`
* Always return 'blobId' and 'size' in Contact/setcreate, Contact/setupdate,
and Contact/get responses.
* Added Bearer authentication for :rfc:`7519` JSON Web Tokens. See
`http_jwt_key` and `http_jwt_max_age` in :cyrusman:`imapd.conf(5)`.
* Added `icalendar_max_size` and `vcard_max_size` :cyrusman:`imapd.conf(5)`
options to limit the size of iCalendar and vCard resources that can be
stored.
* Added `caldav_accept_invalid_rrules` :cyrusman:`imapd.conf(5)` option to
configure whether invalid RRULES should be accepted or rejected. They
were previously always rejected.
* The `event_extra_params` :cyrusman:`imapd.conf(5)` option now supports
a `vnd.fastmail.jmapEmail` selector, which adds a JMAP Email object to
event messages. If you enable this selector, you might consider removing
`vnd.cmu.envelope`, `vnd.cmu.emailid`, and `vnd.cmu.threadid`, as they
would be redundant.
* Added `search_maxsize` :cyrusman:`imapd.conf(5)` option to limit how much
of long message body parts are indexed by Xapian, which can improve indexing
and snippet-generation latency. The default is 4MB. An earlier
implementation applied a hardcoded 4MB limit to entire messages; systems
that had this implementation may notice an increase in index size due to
more text now being indexed.
* The :cyrusman:`squatter(8)` `-s delta` option now requires the delta
argument.
* Added an upper limit to :cyrusman:`sync_client(8)`'s exponential reconnect
backoff, configurable with the `sync_reconnect_maxwait`
:cyrusman:`imapd.conf(5)` option.
* :cyrusman:`sync_client(8)` now recognises when the remote
:cyrusman:`sync_server(8)` has been shut down cleanly, and doesn't log a
bunch of disconnection errors about it
* :cyrusman:`sync_client(8)` `-A` mode now keeps processing subsequent
mailboxes after errors (reconnecting to the replica if necessary), instead
of bailing out at the first error. This means everything that can be
replicated is replicated.
* New :cyrusman:`sync_client(8)` `-N` option to skip users that are currently
being replicated by another process, rather than blocking on the lock only
to have nothing left to do once it's been obtained.
* Added an inactivity timeout for WebSocket connections, configurable with
the `websocket_timeout` :cyrusman:`imapd.conf(5)` option.
* Mailboxes and user metadata directories are now organised on disk by UUID
rather than by mailbox name. See :ref:`relnotes_3.6.0-beta3_storage_changes` below.
* Sieve scripts are now stored in a special mailbox, rather than in
`sievedir`. Compiled bytecode is still stored in `sievedir`. The name of
the mailbox can be overridden with the `sieve_folder`
:cyrusman:`imapd.conf(5)` option (default: '#sieve').
* Experimental `processimip` Sieve action, for updating calendar entries
based on iMIP (:rfc:`6047`) messages.
* Support for JMAP Push (:rfc:`8620`) over EventSource, with polling interval
controlled by the `jmap_pushpoll` :cyrusman:`imapd.conf(5)` option
(default: 60s).
* Experimental support for JMAP Push over WebSockets, if Cyrus has been
compiled with WebSockets enabled. Controlled by the same `jmap_pushpoll`
option.
* When a MIME part Content-Type header incorrectly specifies multiple charsets,
Cyrus now checks each charset for validity and uses the last valid one.
Previously, it would just use the first one, which is often junk when
multiple are present.
* JMAP Email/query and XCONV IMAP extension commands no longer ignore the SEEN
state of messages in the "Trash" mailbox when evaluating conversation flags.
Queries must explicitly exclude the "Trash" mailbox to ignore SEEN state of
messages in "Trash".
* JMAP Contact.importance property is now a per-user property rather than
shared.
* JMAP Contacts now uses Apple-style labels on vCard ADR/TEL/EMAIL properties
(via property grouping)
* JMAP Contacts avatars can now reference any valid blob, not only blobs
originally uploaded via JMAP.
* Preliminary support for building with OpenSSL 3.
.. _relnotes_3.6.0-beta3_storage_changes:
Storage changes
===============
.. Note:: Please consult :ref:`upgrade` prior to upgrading.
Mailboxes and user metadata directories are now organised on disk by UUID
rather than by mailbox name.
At startup (or when you run `ctl_cyrusdb -r` manually),
:cyrusman:`ctl_cyrusdb(8)` will upgrade mailboxes.db to accommodate both
old-style and new-style storage.
By default, new top-level mailboxes will be created in the new style.
Mailboxes that already exist will remain in the old style until you convert
them with :cyrusman:`relocate_by_id(8)`. New mailboxes below the top level
will be created in the same style as their parent mailbox.
The new :cyrusman:`cyr_ls(8)` tool can be used to examine the on-disk
contents of a given mailbox name. :cyrusman:`mbpath(8)` can be used to find
where on disk a given mailbox and its metadata are.
If you want new top level mailboxes to be created in the old style, you
can enable the `mailbox_legacy_dirs` :cyrusman:`imapd.conf(5)` option, which
defaults to **off**. With this turned on, you may still use `relocate_by_id`
to convert them to the new style.
Updates to default configuration
================================
The :cyrusman:`cyr_info(8)` `conf`, `conf-all` and `conf-default` subcommands
accept an `-s <version>` argument to highlight :cyrusman:`imapd.conf(5)`
options that are new or whose behaviour has changed since the specified
version. We recommend using this when evaluating a new Cyrus version to
check which configuration options you will need to examine and maybe set or
change during the process.
* The `reverseuniqueids` :cyrusman:`imapd.conf(5)` option is now deprecated
and unused. Reverse UNIQUEID records are now standard and cannot be turned
off.
Security fixes
==============
* None so far
Significant bugfixes
====================
* Fixed :issue:`3325`: email addresses with quoted-string names were stored in
the cache and search indexes without quotes, which could cause
inconsistencies in handling. Affected mailboxes can be fixed by first
running :cyrusman:`reconstruct(8)` to repair the cache, and then
:cyrusman:`squatter(8)` to reindex the mailbox.
* Fixed :issue:`3421`: PROPFIND <C:schedule-calendar-transp> now returns an
XML element instead of text (thanks Дилян Палаузов)
* Fixed :issue:`3896`: the `-d` (dump) and `-u` (undump) options to
:cyrusman:`ctl_mboxlist(8)` now correctly dump and undump all fields in
mailboxes.db entries. The intermediary file format is now JSON. This change
makes it possible to follow the procedure
for switching `improved_mboxlist_sort` described in
:ref:`enabling improved mboxlist sort`
* Fixed :issue:`4035`: `ctl_cyrusdb -r` now recovers from mailboxes.db
records with missing uniqueids, instead of crashing. A new `-P` option to
:cyrusman:`reconstruct(8)` enables repairing mailboxes whose header files
are missing uniqueids.
