The only change to version 1.0.1 of Arabic Language Kit and Hebrew Language Kit is to include the latest version of WorldScript, version 1.1.
The version of WorldScript included with version 1.0 of these kits may cause a crash when used with Macintosh Performa 475, 476, 575, 577, 578 and Macintosh LC 475 and 575 computers. Additionally, when using the Hebrew Language Kit on other 68LC040-based computers, such as the PowerBook 280 and 280c, the computer may lock up when you switch to the U.S. Keyboard Layout after typing in Hebrew in SimpleText Hebrew or at the Finder.
If you are using version 1.0 of the Arabic or Hebrew Language Kits, you should install the WorldScript Updater v1.
