v1.1 plans have changed a bit. I'll release v1.1.alpha1 soon and hope to
have a stable v1.1 in a month or two. The rest of the features that
didn't make it into v1.1 will go to v1.2. I'll write more about this
when v1.1 alpha is released.
I also did a bit of benchmarking. v1.1's performance improvements are
looking pretty great, it seems to be twice as fast as v1.0.

That will be probably problematic to measure. For example being twice fast and eating four time more resources isn't a great win. That bit me when I wanted to switch from tpop3d to dovecot for pop3 (already done similar switch for imap). It looks like dovecot does much more I/O (even when delivery is used at MTA level so indexes are available) which caused huge problems (unsolved unfortunately). -- Arkadiusz Mi?kiewicz PLD/Linux Team arekm / maven.pl http://ftp.pld-linux.org/
