ext4 is in large part a new filesystem who's name just happens to be similar to what people are running
ext4 is ext3 with a bunch of new extensions (some incompatible): indeed, initially the ext4 work was going to be done to ext3, until Linus asked for it to be done in a newly-named clone of the code instead. It says a lot for the ext2 code and disk formats that they've been evolvable to this degree.
