This is it. The first v1.1 release that actually deserves the "release candidate" name. It contains everything I require from v1.1.0 release. There are two bugs left that I'd like to get fixed, but they won't block v1.1.0 release:

• index_mailbox_set_recent_uid() assert (reported by Diego Liziero)
• Maildir not always finding new messages and returning them as empty (reported by Anders).

The major change in v1.1.rc6 release is the SORT indexing half-rewrite. I hadn't much stress tested that code before, and once I started I just kept finding more and more weird bugs and it became extremely difficult to figure out how to fix them, so I finally decided to just redesign how it's supposed to work and then implemented that.

The resulting sort code is a lot cleaner and it should also perform better (although it could still be improved a bit: the basic binary searching could be replaced with one that first binary searches between already-looked-up sort-strings and only after that binary searches the resulting space which requires slower sort-string lookups). Hopefully there are also no stupid bugs left like returning messages in wrong sort order. :)

I've been wasting time this past week getting new stuff for my new apartment, but that's nearly done now. I think (hope) I'm going to be more productive in here, there are less neighbours behind walls/floors (just 1), so less potential for annoying noises. :) Thinking also seems to work better when there's more space to walk around.

And finally, the changes since v1.1.rc5:

* Index file format changed a bit. If an older Dovecot v1.1 reads
  index files updated by rc6+, they may give "Invalid header record
  size" or "ext reset: invalid record size" warnings. v1.0 won't give
  these errors.
* IMAP: LIST .. RETURN (X-STATUS) command return now LIST entries
  before STATUS entries.
* zlib plugin: Uncompress if the message begins with zlib header
  instead of looking at the 'Z' flag. This fixes copying with hard
  links. Based on a patch by Richard Platel.

+ IMAP: SORT index handling code was half-rewritten to fix several bugs
  when multiple sessions were sorting at the same time. The new code is
  hopefully also faster.
+ Maildir: If POP3 UIDL extra field is found from dovecot-uidlist,
  it's used instead of the default UIDL format (or X-UIDL: header).
  This allows easily preserving UIDLs when migrating from other POP3
  servers. Patch by Nicholas Von Hollen @ Mailtrust.
+ Maildir: ,W=<vsize> is now always added to maildir filenames
+ deliver: Avoid reading dovecot-uidlist's contents if possible.
+ Added %T modifier = Trim whitespace from end of string
- IMAP: Fixed some bugs in LIST-EXTENDED implementation.
- IMAP: If client tries to change the selected mailbox state while
  another command is still running, wait until the command is finished.
  This fixes some crashes and other unwanted behavior.
- allow_nets userdb setting was broken with big endian CPUs
