Hi Thomas,
We guarantee back compatibility, ie reading files written with an old version of ROOT. The inverse is more tricky. We have made an effort so far to support forward compatibility. This did not happen when we started version 4 (to support correctly the bool type). So you cannot read files written with version 4 with older version like 3.05.
Could you give more details on the problems you have experienced in moving to version 4?
