what do you mean?
if canvas size (and zoom for that matter) are saved as attributes of the 
diagram element you will not break anything. that is the beauty of XML.
old versions of Umbrello will simply not check for that attribute.
New versions will, and if the element doesnt have the attribute it will 
(should) use the default value.

is that what you were talking about, or what do you mean with "serializing"??
serializing was the term used for saving/loading to the old binary file 
format, but we are not saving binary anymore, and reading should simply use 
the default. Since there is no way that file has been written with size/zoom 
info (because UML Modeller did not support that) you are on the safe side.
