>   * imap: When BINARY FETCH sees invalid content, return NO [PARSE] reply

>   * pop3c: Increase timeout for PASS command to 5 minutes.
>   * Mail access errors are no longer ignored when searching or sorting.
>     With IMAP the untagged SEARCH/SORT reply is still sent the same as
>     before, but NO reply is returned instead of OK.

>   + auth: Support filtering by SASL mechanism: passdb { mechanisms }
>   + Shrink the mail processes' memory usage by not storing settings
>     duplicated unnecessarily many times.
>   + imap: Add imap_fetch_failure setting to control what happens when
>     FETCH fails for some mails (see example-config).
>   + imap: Include info about last command in disconnection log line.
>   + imap: Created new SEARCH=X-MIMEPART extension. It's currently not
>     advertised by default, since it's not fully implemented.
>   + fts-solr: Add support for basic authentication.
>   + Cassandra: Support automatically retrying failed queries if
>     execution_retry_interval and execution_retry_times are set.
>   + doveadm: Added "mailbox path" command.
>   + mail_log plugin: If plugin { mail_log_cached_only=yes }, log the
>     wanted fields only if it doesn't require opening the email.
>   + mail_vsize_bg_after_count setting added (see example-config).
>   + mail_sort_max_read_count setting added (see example-config).

>   - imap: FETCH X-MAILBOX may have assert-crashed in virtual mailboxes.
>   - imap: Running time in tagged command reply was often wrongly 0.
>   - search: Using NOT n:* or NOT UID n:* wasn't handled correctly
>   - director: doveadm director kick was broken
>   - director: Fix crash when using director_flush_socket
>   - director: Fix some bugs when moving users between backends
>   - imapc: Various error handling fixes and improvements
>   - master: doveadm process status output had a lot of duplicates.
>   - autoexpunge: If mailbox's rename timestamp is newer than mail's
>     save-timestamp, use it instead. This is useful when autoexpunging
>     e.g. Trash/* and an entire mailbox is deleted by renaming it under
>     Trash to prevent it from being autoexpunged too early.
>   - autoexpunge: Multiple processes may have been trying to expunge the
>     same mails simultaneously. This was problematic especially with

>   - auth: %{passdb:*} was empty in auth-worker processes
>   - auth-policy: hashed_password was always sent empty.
>   - dict-sql: Merge multiple UPDATEs to a single statement if possible.
>   - fts-solr: Escape {} chars when sending queries
>   - fts: fts_autoexpunge_exclude = \Special-use caused crashes
>   - doveadm-server: Fix leaks and other problems when process is reused
>     for multiple requests (service_count != 1)
>   - sdbox: Fix assert-crash on mailbox create race
>   - lda/lmtp: deliver_log_format values weren't entirely correct if Sieve
>     was used. especially %{storage_id} was broken.
