At some point between August and September there appears to have been a number of incorrect auto-unsubscriptions against some of the Hibernate mailing lists (hibernate-dev for sure). I am not going to point fingers as to who is to blame in this. I do however apologize for any inconvenience this might have caused. If you find yourself part of this group, the current direction I am receiving is that you will just have to re-subscribe :( if you happen to still have the unsubscribe notification email I would be very interested in getting it to pass along to our mailman admins; you can forward them to me directly.
