The Choose Application command takes two new optional parameters, multiple selections allowed, and as to specify the type of the result to be returned (application, alias to the application or file of the application).

The old New File command has been renamed as Choose File Name, with the same parameters. This makes it possible for the first time to tell the Finder to make new file and get the same behavior as make file.

In AppleScript 1.5 and later, the Round command now can take an additional enumerated parameter: as taught in school. With this parameter, numbers whose fractional parts are less than .5 are rounded towards zero, and fractional parts of .5 and above are rounded away from zero.
