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
