It seems that the only change in the datafile is related to value labels.
Stata 9 now allows value labels to be up to 32,000 characters long and
in different languages.  So if your Stata 9 dataset does not take advantage
of these new features, can it still be read by Stata 8 and by data transfer
software like DBMS/Copy and StatTransfer?
-svyset- has a lot more options now, and those get saved with the dataset. So, perhaps that also creates compatibility problems across versions? Apparently not, however, since it says at

http://www.stata.com/help.cgi?save

"If you are using Stata 9 and want to save a file so that it may be read by someone using Stata 8, simply use the save command. Stata 8 and Stata 9 share the same dataset format. Stata 9 allows value labels to be up to 32,000 characters long. If Stata 8 tries to read a Stata 9 dataset with value labels that exceed the Stata 8 limit (244 for Stata/SE; 80 for Stata Intercooled), Stata 8 will ignore those labels and read the rest of the dataset.
