New, Continued, and Expanded Support:
================================================================
I would like to thank the Society of Exploration Geophysicists for
the expanded support through a generous grant from the SEG Foundation!

I would also like to thank the Gas Research Institute for its 
support for Seismic Unix for the past year.

My thanks also goes to the Consortium Project on Seismic Inverse
Methods for Complex Structures at the Center for Wave Phenomena
for its continuing financial support of the SU project.

User's Manual Update:

The user's manual has been greatly updated, thanks in large
part to the  University of Calgary. The members of the CREWES
project at U Calgary kindly invited me to give a short course on SU,
in February, which encouraged me to expand and update the manual.

There is also a Japanese language version of the New SU Users Manual
avalable at:  http://tansa1.kumst.kyoto-u.ac.jp/suj/

================================================================
The Seismic Unix Project depends heavily on contributed code
extensions and bug fixes from the SU users community.

Please note, if you contributed new code, or changes and don't
see it on this list, it will likely be in the next release.

================================================================

================================================================
Resolved issues:
================================================================
The completed CWP/SU package may now be installed on DEC Alpha
system using "GNU Make" and the "GCC compiler"
Thanks to: Gilles Grandjean of BRGM, Orleans, France.

================================================================
Unresolved Issues:
================================================================
-General X-windows Graphics issues:
The question of supporting 8bit vs. 16bit vs. 24bit vs. 32bit
 graphics is becoming more of an issue. Currently, the 
CWP/SU graphics only supports 8bit graphics systems. Any help
that could be rendered to get the Seismic Unix image plots
to work under 16,24, and or 32 bit graphics, as well as
the current 8 bit graphics would be greatly appreciated.

-Tape support: More SEG-D types need to be supported. (May nearly
be resolved, thanks to the efforts of Stew Levin of Mobil, but
I am still testing his code.)

-Well log support:  Reading in well logs for synthetic seismogram
construction would be helpful. 

-DEC Alpha:
There have been reports that
X-windows codes do not work when the package is installed with
the native "cc" compiler. There is some small change that
was introduced between Release 28 and Release 30 that did this,
but we have not been able to dicern what this is.

-Xtcwp/main/xmovie,xgraph
These windows will not accept focus under linux/XFree86.  We know
a kludge to correct this, but since it makes no sense, we refuse
to put it in the distribution.

-Xtcwp/main/xmovie
The grid1=, grid2= options cause an abort under linux/XFree86 and
possibly other platforms.  Message is:
	Error: Cannot perform malloc
This seems like a compiler error since innocuous changes in the code
or compiling without optimization makes the problem go away.  We
distributed the current version with such an innocuous change
to accomodate this: we changed the dimension of args[] from 100 to 98.

-su/main/suresstat.c - Does not really work for general datasets, suggest
			that it be broken into two programs, one to compute
			source statics and one to compute receiver statics.

-Refl/main/sureflpsvsh.c - This code works for some input datasets, but
			still needs bugs fixed.
================================================================

Thank you, to all who have helped make CWP/SU Release 32 the best
release so far!

================================================================
================================================================
PS:  The Society of Exploration Geophysicists Annual Meeting will
     be held in New Orleans, the week of 13 September 1998.  I
     don't have a booth, but will be spending a lot of time
     walking the convention floor, shaking hands, and meeting with
     current and potential SU users. I hope to see you there!
