Release Notes: The "add" and "change" functions in 1.0 wouldn't work with some standards-compliant browsers. This has been fixed, along with some problems with the "Image Upload" function. This is a recommended upgrade for all users.
Release Notes: A built-in search engine, two-level menus, support for antique browsers, and many other minor changes. However, the code also requires current versions of PHP (>=4.1.x with 'superglobals') and MySQL (>=3.23.23).
