Details on how to upgrade are available at:
It seems that the 4.0.x branche will not live very long anymore, so
upgrading to 4.1.x (via 4.0) might be a good idea if he wants to upgrade.
Lists all the changes in each version. The major features can be found
in the D.2 and D.3 documents (for 4.1 and 4.0).
As a hoster he will probably also need to support PHP, etc. There is
also a nice book by Adam Trachtenberg: "Upgrading to PHP5" (O'Reilly,
July, 2004, 352 p., ISBN 0596006365) which also contains information on
how to migrate to PHP5/MySQL4.1 in several steps.
