[Dovecot] Dovecot Stable (or: When is 1.0 coming to a server near you?)

I'm mainly just curious, but what version of dovecot is considered to be stable enough to be running in a production environment?

We're running the 0.99.13 version shipped with FC3 and, while experiencing great performance gains over UW-IMAP, we have hit a couple of snags here and there (random and infrequent characters at the beginning of a mailbox, periodic duplication of a message here and there, etc). I figure we should upgrade to something a bit more current, but I am not sure what the "recommended" verion would be..

Also, perhaps more important, what's the roadmap to getting 1.0 finalized? What's the timeframe? :-)
