[Dovecot-news] v2.2.17 release candidate 2 released



Changes since rc1:
- Compiling fix for fs-compress in Solaris and maybe others.
- Implemented Cassandra CQL support as lib-sql backend. This is mainly usable as dict-sql backend.
- lib-fts fixes and improvements
- Some other small random changes

If no new issues are found, v2.2.17 final should be out in a day or two. (Actually looks like I have a few more bugs that probably will be fixed for it.)

Changes since v2.2.16:

* Dovecot no longer checks or warns if a mountpoint is removed. This was causing more trouble than it was worth. Make sure that all the mountpoints that Dovecot accesses aren't writable by mail processes when they're unmounted.
* dict server wasn't properly escaping/unescaping data. Fixing this broke backwards compatibility with data that contains line feeds. This hopefully affects only very few installations. If you're using dict to save multiline data (Sieve scripts to SQL), you may be affected.
* imap: SPECIAL-USE capability is no longer advertised if there are no special_use flags specified for any mailboxes.

+ lmtp: Added lmtp_hdr_delivery_address setting to specify whether to include email address in Delivered-To: and Received: headers.
+ Added initial version of full text search library, which includes language-specific text normalization and filtering. This is still in development, but it's already possible to use for testing with fts-lucene and fts-solr.
+ lda, lmtp: deliver_log_format can now include %{delivery_time}, which expands to how many milliseconds it took to deliver the mail. With LMTP %{session_time} also expands to how many milliseconds the LMTP session took, not including the delivery time.
+ lmtp proxy: Mail delivery logging includes timing information.
+ imap: Most IMAP commands now include in the tagged reply how many milliseconds it took to run the command (not counting the time spent on waiting for the IMAP client to read/write data).
+ director: Implemented director_proxy_maybe passdb extra field to be able to run director and backend in the same Dovecot instance. (LMTP doesn't support mixed proxy/non-proxy destinations currently.)
+ doveadm: Added -F <file> parameter to read a list of users from the given file and run the command for all the users. This is similar to -A parameter reading the list of users from userdb lookup.
+ Implemented initial Cassandra CQL support as lib-sql backend. It's only usable as dict backend currently.
- auth: If auth_master_user_separator was set, auth process could be crashed by trying to log in with empty master username.
- imap-login, pop3-login: Fixed crash on handshake failures with new OpenSSL versions (v1.0.2) when SSLv3 was disabled.
- auth: If one passdb fails allow_nets check, it shouldn't have failed all the other passdb checks later on.
- imap: Server METADATA couldn't be accessed
- imapc: Fixed \Muted label handling in gmail-migration.
- imapc: Various bugfixes and improvements.
- Trash plugin fixes by Alexei Gradinari
- mbox: Fixed crash/corruption in some situations when the first mail was expunged.
