That is an incorrect assumption.

Yes. The relevant information for *each* version of the
Unicode Standard is at:
http://www.unicode.org/standard/Versions/enumeratedversions.html
As it happens, almost *every* data file was updated for
Unicode 4.0, so almost everything is available specifically
in http://www.unicode.org/Public/4.0-Update/ The only
normative files that were unchanged from an earlier version were:
http://www.unicode.org/Public/3.2-Update/Jamo-3.2.0.txt
http://www.unicode.org/Public/3.2-Update/Unihan-3.2.0.zip
Of course, the update for Unihan.txt was one of the main reasons
for the Unicode 4.0.1 release.
The only other file that was unchanged was the character index
to the book:
http://www.unicode.org/Public/3.2-Update/Index-3.2.0.txt
which, for production reasons, was not updated again until the
release of Unicode 4.0.1.
