Hi Karl,

You changed both the preamble and the postscript of the package, which 
means that both scripts will be evaluated on update. You also left the 
previous preamble and postscript in place (which were not very user 
friendly, because they mangled with preferences), which means that those 
preference changes will be applied again when your version or Morphic is 
loaded.
So, if I update my image which has deprecation warnings disabled, my 
setting will be erased and the deprecation warnings will be enabled by 
the postscript. In an unfortunate scenario such change could render my 
image unresponsive.

When you update any of these scripts, please make sure that only things 
that need to be evaluated for the current .mcm stay there. Delete 
everything else from the scripts.

Levente
