Talking about "padding of structures", as this will be one of those changes most likely, I had suggested previously in private email: Can't we start collecting all those somewhere, perhaps on the wiki, and do one big padding day, one commit for all and everything? This would have several advantages: 1) no ABI breakage in HEAD as v-structs would possibly change in size 2) actual documentation of A|KB|PI relevant structures which would be good to have them written down finally after I heard people talking about this for multiple releases now. 3) a list of things we might need to work on in the future to reduce the problem and also a list for the time 9.x would come;-) just my 0.01$ /bz -- Bjoern A. Zeeb The greatest risk is not taking one.
