Advice for Cyrus version

[AJ]

Hey guys,
   I am trying to decide what version of cyrus-imapd to go with in our 
rollout.  I have seen some issues in releases after 2.2.3.
I am thinking of sticking with 2.2.3 for now, but read that the 
mailboxes.db file should not be in Berkeley db format, which i think is 
true for 2.2.3.  Any advice would be great.

Thanks.
AJ
