Also, there's new documentation which is current for ACT5:

For the few interested parties out there, here are the release
notes:

___________________________________________________________________
VERSION 2.1b6

* Released June 5, 2002.

* Many users have complained about the fact that RPM takes over the
mouse even when their model doesn't use the mouse. Good point.
There is now a paramter called :NEEDS-MOUSE which can be set to NIL
to disable RPM taking over the mouse.

* Outputting speech now outputs sound to the audicon. Also added a
SUBVOCALIZE command which outputs the sound only to the audicon,
but not to the environment.

* Added an internal hook function to support the environment's
stepper.

* Lingering bug with display processing happening mid-production
resolved by Dan adding a priority system to the queue.

* Removed unusued OBJECTS slot from audio-event chunks and added
EVENT slot to sound chunks to parallel vision.

* Added a couple items to the stepper, including printing the icon
and suppressing the menu.

* Object tracking now updates the visual location buffer to the
location of the tracked object, and it tracks the visual feature
rather than the actual screen object.

* Added text color processing stuff (used to be an extra) to MCL
interface.

* Added BUILD-FEATURES-FOR methods for radio buttons and check
boxes (MCL-only).

* Made PM-PRINT-ICON output more tabular--this should be easier to
read.

* PROCESSOR wasn't being set to BUSY correctly for some motor
events. Fixed.

* Backquoted some macros to make ACL happier.

* Fixed one more (and hopefully the last one) vector bug glitch.
