Note that the download URLs are now https with a certificate from Let's Encrypt.

* dovecot.list.index.log rotation sizes/times were changed so that
the .log file stays smaller and .log.2 is deleted sooner.

+ Added mail_crypt plugin that allows encryption of stored emails.
See http://wiki2.dovecot.org/Plugins/MailCrypt
+ stats: Global stats can be sent to Carbon server by setting
stats_carbon_server=ip:port
+ imap/pop3 proxy: If passdb returns proxy_not_trusted, don't send
ID/XCLIENT
+ Added generic hash modifier for %variables:
%{<hash algorithm>;rounds=<n>,truncate=<bits>,salt=s>:field}
Hash algorithm is any of the supported ones, e.g. md5, sha1, sha256.
Also "pkcs5" is supported using SHA256. For example: %{sha256:user}
or %{md5;truncate=32:user}.
+ Added support for SHA3-256 and SHA3-512 hashes.
+ config: Support DNS wildcards in local_name, e.g.
local_name *.example.com { .. } matches anything.example.com, but
not multiple.anything.example.com.
+ config: Support multiple names in local_name, e.g.
local_name "1.example.com 2.example.com" { .. }
- Fixed crash in auth process when auth-policy was configured and
authentication was aborted/failed without a username set.
- director: If two users had different tags but the same hash,
the users may have been redirected to the wrong tag's hosts.
- Index files may have been thought incorrectly lost, causing
"Missing middle file seq=.." to be logged and index rebuild.
This happened more easily with IMAP hibernation enabled.
- Various fixes to restoring state correctly in un-hibernation.
- dovecot.index files were commonly 4 bytes per email too large. This
is because 3 bytes per email were being wasted that could have been
used for IMAP keywords.
- Various fixes to handle dovecot.list.index corruption better.
- lib-fts: Fixed assert-crash in address tokenizer with specific input.
- Fixed assert-crash in HTML to text parsing with specific input
(e.g. for FTS indexing or snippet generation)
- doveadm sync -1: Fixed handling mailbox GUID conflicts.
- sdbox, mdbox: Perform full index rebuild if corruption is detected
inside lib-index, which runs index fsck.
- quota: Don't skip quota checks when moving mails between different
quota roots.
- search: Multiple sequence sets or UID sets in search parameters
weren't handled correctly. They were incorrectly merged together.
