In the course of performing the upgrade to 4.0.10.17, the following notes are relevant
and may be useful when performing future phpMyAdmin upgrades.

1) config.inc.php was copied over from the old install.
2) the tests and setup directories were deleted.
3) The PMA_MYSQL_CLIENT_API check in index.php was disabled.
4) libraries/common.inc.php was edited to set the session dir.
5) This was the latest version that still supported MySQL 5.0 and higher at this time.
