Hi all,

just another question to the cinelerra source code gurus --
what is the "standard procedure" if you want to extend some object with
a new property? I can figure out how to save and re-read property values
from the session XML. But what is your policy to handle old XML?
Is there a version numbering of session file formats somewhere?
Is there a "migration component" somehwere or is it the responsibility
of every single component to handle missing values or migrate old values?

I just don't want to do nasty things to cinelerra's decent sourecode :-)

Hermann
