There are now fixes in CVS for both the pre-login vulnerability and the
sieve vulnerability for 2.0 (cyrus-2-0-tail) and 2.1 (HEAD).  I expect
them to be migrated over to the 2.2 branch (cyrus-imapd-2_2) later today
or early tomorrow.

We'll be officially deprecating 1.x as of now (removal from the web
and ftp sites except for the archives, etc).

I expect to have the new releases out within a day or so after I can give
them some further testing.
