TUI version 1.4 is coming. This includes SPICam control, focus script 
enhancements and an improved enclosure widget.

A very stable and well-tested prerelease 1.4b5 is available now (from 
the usual prerelease location:
<http://www.apo.nmsu.edu/35m_operations/TUI-images/files/>). I expect 
to release 1.4 later this week after some tests of the new tertiary 
rotation control.

The rest of this message is for people who install TUI on unix, 
telling you how to prepare for TUI 1.4.

TUI 1.4 uses numpy instead of numarray and Numeric. Thus to run TUI 
1.4 you must install:
- numpy (1.0 or later; the current release is best)
- A numpy-compatible version of pyfits (1.1 or later)

*** WARNING ***

Once you install pyfits 1.1 or later, TUI 1.3 will STOP DISPLAYING 
GUIDE IMAGES until you define environment variable NUMERIX to 
numarray. This tells pyfits to run with numarray instead of numpy. 
Please only do this for TUI 1.3; it is not wanted for TUI 1.4.

Thus if you want to make both TUI 1.3 and TUI 1.4 available to your 
users (recommended for safety) please define NUMERIX=numarray in the 
shell script that starts TUI 1.3, but not TUI 1.4.

You can verify that you've done this correctly (even during the day 
and during the shutdown) by taking a short guider exposure and 
verifying that the image is displayed.

Note: TUI 1.4 no longer uses numarray or Numeric. So you may delete 
those deprecated libraries once you are sure you won't need them for 
TUI 1.3 or anything else.
