Dear VMD-L,
  I have just packaged up VMD 1.4 beta 4 and made it available
on the web site. This new (and hopefully final) beta version
of VMD 1.4 has the following improvements over beta 3:

 o The "within" distance-based atom selections are 50 to 100 times faster
   than they used to be. (new grid-based spatial decomposition accelerates
   these atom selections tremendously, the bigger the molecular system,
   the bigger the performance improvement is...)
 o Brand new support for Gromos96 ASCII formatted trajectory files
 o New support for Charmm format DCD trajectory files.
 o Support for new forms of multi-structure PDB files.
 o All Mesa versions are now built using Mesa 3.1 (higher speed for
   non-accelerated Unix systems such as Linux)
 o Fixed bug reports 51, 57, 69, and 70 (see the VMD bug database for details)
 o Updated VMD to work with Solaris 7 x86 with Sun's WS C/C++ 6.0 tools
 o Updated VMD to work on HPUX 11.0
 o numerous small efficiency and performance improvements
   
There are just a few minor nits that need tweaking before the final
release, which is what I expect that the next release will be.
Please let me know if you encounter any problems with this release,
so that any important bugs that are found can be quashed before
the final 1.4 release.

Thanks for using VMD!
