+	- Fix assertion panic occurring when managesieve service fails to open
+	  INBOX while saving a Sieve script. This was caused by a lack of
+	  cleanup after failure.
+	- Fix specific messages causing an assert panic with actions that
+	  compose a reply (e.g. vacation). With some rather weird input from the
+	  original message, the header folding algorithm (as used for composing
+	  the References header for the reply) got confused, causing the panic.
+	- IMAP FILTER=SIEVE capability: Fix FILTER SIEVE SCRIPT command parsing.
+	  After finishing reading the Sieve script, the command parsing
+	  sometimes didn't continue with the search arguments. This is a time-
+	  critical bug that likely only occurs when the Sieve script is sent in
+	  the next TCP frame.
