v2.3.8 2019-10-08  Aki Tuomi <aki.tuomi@open-xchange.com>

	+ Added mail_delivery_started and mail_delivery_finished events, see
	  https://doc.dovecot.org/admin_manual/list_of_events/ for details.
	+ dsync-replication: Don't replicate users who have "noreplicate" extra
	  field in userdb.
	+ doveadm service status: Show total number of processes created.
	+ When logging to syslog, use instance_name setting's value for the
	  ident. This commonly is added as a log prefix.
	+ Base64 encoding/decoding code was rewritten with additional features.
	  It shouldn't cause any user visible changes.
	- v2.3.7 regression: If a folder only receives new mails without any
	  other mail access, dovecot.index.log keeps growing forever and
	  dovecot.index keeps being rewritten for every mail delivery.
	- dsync-replication may lose keywords after syncing mails restored from
	  another replica. This only happened if the mail only had keywords and
	  no system flags.
	- event filters: Non-textual event fields could not be filtered using
	  wildcards.
	- auth: Scope parameter was missing from OAuth password grant
	  request.
	- doveadm client-server communication may hang in some situations.
	  It is also using unnecessarily small TCP/IP packet sizes.
	- doveadm who and kick did not flush protocol output correctly.
	- imap: SETMETADATA with literal value would delete the metadata value
	  instead of updating it.
	- imap: When client issues FETCH PREVIEW (LAZY=FUZZY) command, the
	  caching decisions should be updated so that newly saved mails will
	  have the preview cached.
	- With mail_nfs_index=yes and/or mail_nfs_storage=yes setuid/setgid
	  permission bits in some files may have become dropped with some NFS
	  servers. Changed NFS flushing to now use chmod() instead of chown().
	- quota: warnings did not work if quota root was noenforcing
	- acl: Global ACL file ignored the last line if it didn't end with LF.
	- doveadm stats dump: With JSON formatter output numbers using the
	  number type instead of as strings
	- lmtp_proxy: Ensure that real_* variables are correctly set when using
	  lmtp_proxy.
	- event exporter: http-post driver had hardcoded timeout and did not
	  support DNS lookups or TLS connections.
	- auth: Fix user iteration to work with userdb passwd with glibc v2.28.
	- auth: auth service can crash if auth-policy JSON response is invalid
	  or returned too fast.
	- In some rare situations "ps" output could have shown a lot of "?"
	  characters after Dovecot process titles.
	- When dovecot.index.pvt is empty, an unnecessary error is logged:
	  Error: .../dovecot.index.pvt reset, view is now inconsistent
	- SMTP address encoder duplicated initial double quote character when
	  the localpart of an address ended in '..'. For example
	  "user+..@example.com" became ""user+.."@example.com in a
	  sieve redirect.
