You can get 1.0.15 which is the recent stable for the 1.0 series, and you can
get 1.1.16 which has many new improvements over 1.0, and is the current stable
branch. I think the 1.1 branch has some changes to the auth code that might
help. Read the dovecot wiki for the steps you need to follow to upgrade,
especially if you want to go back.

I really recommend you at least go to the 1.0 branch instead of the 0.99 beta
in CentOS 4. The indexing improvements alone are worth it.
