Comment (by cohosh):

 Replying to [comment:13 cohosh]:
 >  * Make it backwards compatable. I'm thinking of doing this by having an
 extra field in the header that should be set to all zeros. If it's not
 zeros, we just forward the data as is. If it is zeros, we extract the
 header.
 Actually another way of doing backwards compatability is to make a new
 handler for the new version.
