It's been a while since v2.2.1. I think all of the bad bugs in v2.2
series should be fixed by now, so here's a new release. I think there
are still some small URLAUTH bugs left though, so you might want to wait
before enabling it in production (imap_urlauth_host is empty by default,
which disables it).

	+ zlib: Keep the last mail cached uncompressed in a temp file. This
	  fixes performance when doing small partial fetches from a large
	  mail.
	+ acl: If plugin { acl_defaults_from_inbox = yes } is set, get the
	  default ACLs for private and shared namespaces from the user's INBOX.
	  (This probably will become default in v2.3.)
	+ pop3: Added pop3_deleted_flag setting to switch POP3 deletions to
	  only hide the messages from POP3, but still be visible via IMAP.
	- ACL plugin: Mailbox creation wasn't actually checking any ACLs
	  and always succeeded (due to some v2.2 API changes). The created
	  mailbox couldn't have been accessed though, so this couldn't have
	  caused any data leak.
	- IMAP: Various URLAUTH fixes.
	- IMAP: Fixed a hang with invalid APPEND parameters.
	- IMAP LIST-EXTENDED: INBOX was never listed with \Subscribed flag.
	- mailbox_list_index=yes still caused crashes.
	- maildir: Fixed a crash after dovecot-keywords file was re-read.
	- maildir: If files had reappeared unexpectedly to a Maildir, they
	  were ignored until index files were deleted.
	- Maildir: Fixed handling over 26 keywords in a mailbox. 
	- Maildir++: Fixed mail_shared_explicit_inbox=no 
	- namespace { prefix="" list=no } was listing mailboxes.
	- imap/pop3-login proxying: Fixed a crash if TCP connection succeeded,
	  but the remote login timed out.
	- Case-insensitive search/sort didn't work correctly for all unicode
	  characters, as specified by i;unicode-casemap comparator. If full
	  text search indexes were used, they need to be rebuilt for old mails
	  to be handled correctly. (This bug has existed always in Dovecot.)
