#911
I actually used 2614 to do a restore - it worked fine.
If you look at the bugs for 2619, they are minor really and most importantly do not affect the integrity of the actual backup.
Same happened with 7.0 - a number of quick fixes mainly for obscure stuff, and it settled down.
I see nothing in these updates to be duly concerned about. I would love to see the opposition fix bugs as quickly (especially Acronis who used to take months even for really serious bugs).
