Here's one source I found via google.  Not sure if it is the most up
to date.

http://java.sun.com/docs/books/vmspec/2nd-edition/UpdatedClassFileFormat.pdf

AIUI, the major version in 1.4 was 48 and the major version in 1.5 is 49.

There are differences between 1.3, 1.4, and 1.5.
As I remember, 1.4 introduce a little difference in verification.
1.5 adds a bunch of new things, including an extension to the
semantics of 'ldc'.
