Answer: The Open Group's press release for Motif 2.1 is available at:
http://www.rdg.opengroup.org/press/5feb97.htm

A technical report is also available at:
http://www.opengroup.org/tech/desktop/motif/motif.data.sheet.htm

The major differences from Motif 2.0 are:

1) The CS text widget from Motif 2.0 is not included.

2) Motif 2.0 word-size independent UID files are no longer supported.  Only
the Motif 1.2 word-size dependent format is supported.

3) To promote convergence with dtwm, mwm's panning, virtual screen, and
workspace features have been removed

4) Support was added for the X print server, including a new print dialog
widget

5) The Motif libraries are now thread-safe (if the underlying libraries and
system are also thread-safe)

6) Several internationalization features were added, including an on-the-spot
input method and vertical text writing

7) Motif 2.1 is based on X11R6.2 and will work properly with X11R6.3
