major changes since 2.0.x:
plugins now use UTF-8 mailbox names rather than mUTF-7
auth_username_format default changed to %Lu
solr full text search backend changed to use mailbox GUIDs instead of
mailbox names, requiring reindexing everything
v2.0.14: Index reading could have eaten a lot of memory in some
situations
mbox: Fixed crash during mail delivery when mailbox didn't yet have
GUID assigned to it.
zlib+mbox: Fetching last message from compressed mailboxes crashed.
userdb extra fields can now return name+=value to append to an
existing name
script-login attempted an unnecessary config lookup, which usually
failed with "Permission denied".
lmtp: Fixed parsing quoted strings with spaces as local-part for
MAIL FROM and RCPT TO.
imap: FETCH BODY[HEADER.FIELDS (..)] may have crashed or not
returned all data sometimes.

using separate ALT, INDEX or CONTROL paths.

script-login binary wasn't actually dropping privileges to the
user/group/chroot specified by its service settings.
Fixed potential crashes and other problems when parsing header names
that contained NUL characters.
dsync: More fixes to avoid hanging with remote syncs
dsync: Many other syncing/correctness fixes
