I agree with your comment. Adding new features, functions to a system 
may reveal old hidden bugs. But we think that a published release should 
be stable to a certain extent and should allow the developer to work 
comfortably with the system. This was the main reason for the rollback.
We had memory problems with the release that used the old object file 
format already. It is probably easier to find these in the rolled back 

Best regards
