I'm pretty hopeful that virtual mailbox code is finally crash-free. If people don't find many problems from this release, I'm thinking that rc5 could come in a couple of weeks and that would be renamed to v1.2.0 after a week or so if no one has reported bugs.

v1.2.rc4 2009-05-17 Timo Sirainen tss@iki.fi

* If /dev/arandom exists, use it instead of /dev/urandom (OpenBSD).
* When logging to a file, the lines now start with a timestamp instead
  of "dovecot: " prefix.

+ IMAP: When multiple commands are pipelined, try harder to combine
  their mailbox syncing together. For example with Maildir pipelining
  STORE 1:* +FLAGS \Deleted and EXPUNGE commands the files won't
  be unnecessarily rename()d before being unlink()ed.
+ imap-proxy: Send backend's CAPABILITY if it's different from what
  was sent to client before.
+ IMAP: struct mail now keeps track of all kinds of statistics, such
  as number of open()s, stat()s, bytes read, etc. These fields could
  be exported by some kind of a statistics plugin (not included yet).
+ IMAP: SEARCH command now dynamically figures out how to run about
  0.20 .. 0.25 seconds before seeing if there's other work to do.
  This makes the SEARCH performance much better.
