TimberWolf Systems, Inc. release version 1.3.0 date 10/15/96.
Problems remedied
*****************
Program:License Server
--------------------
Now license server is backward compatible.  Now a new version of
TimberWolf is able to coexist with older executables with respect
to the license server.

Program:TimberWolfGR
--------------------
Fixed a problem with generating a steiner point on top of a macro cell
in the classical case.  Fixed problems with end arounds when they are
prohibited.  Now only call the compactor when the macros are overlapping.
This was changing the y location of macro cells in cases where it should
remain the same.  Fixed problems with the internal routing graph which
was creating incorrect routes.  Now the global router can handle rows
with no cells in it.  In incremental mode, correctly identify used
feed thrus.  Added a more robust .pin file parser in incremental mode.
Now the global router is deterministic, that is, with the same random
seed, the result will be reproducible.

Program:TimberWolfSC
--------------------
Fixed problem with ECO mode when rows have have implicit exceptions or
gaps.  Fixed orientaion problems when used in the parallel mode.

Program:syntax
--------------
Now check to make sure the user adds a feedthru cell to the design.

Program:Cluster
---------------
Fixed crash with preplaced feedthru cells.   Now COVER cells work
properly in the cluster mode.

Program:TWtranslate
-------------------
Fixed problems with twread_tw function.  Updated the twhelp function message.
Now properly handle rename statements for ports, models, and cells when
reading edif.

General
-------
Fixed problems with fixed constraints with only cell center coordinates.
Fixed problems with display during parallel mode.  Fixed problem with
exposure events during a graphics wait loop.  Fixed problems with cells
fixed to the right side of a row being incorrectly processed.

New Features
************
Program:Cluster
---------------
Now the PORT and COVER models work in the hierarchical mode.

Program:TimberWolfSC
--------------------
Now TimberWolfSC has a new algorithm which insures that cells do not
exceed the row length in gate array mode.  Added cell gridding which forces
cells to a user specified grid.  User may specify x_cellgrid in the parameter
file.  Added verification routine to insure that no overlap ocurrs.
Now TimberWolfSC correctly detects the eco mode even when the hierarchical
mode has been requested.  In hierarchical mode, the random seeds are
adjusted so that each probe yields a different result, yet the runs
are deterministic.

Program:TimberWolfGR
--------------------
Added a new global routing strategy - minimize peak density.  If 
strategy : min_peak
is requested in the .par file, the global router will attempt to equalize
the congestion among all of the regions.  Added the new options: 
modify_prerouting, io_end_around, and reassign_feeds.

Program:Genrows
---------------
Now the "Align Rows" function modifies the left and right edges of the
rows rather than the row separation.  The separation function has now been 
renamed the more appropriate "Match Separation".  Added a row yoffset
feature for each tile.  It also may be set globally in the .par file and
from the parameters menu.

Program:TWtranslate
-------------------
Added twvirtual_rows function for building a .blk file.  Now tell the user
the default file for each command.  Added the twwrite_edif command.

General
-------
Added the ExitAll command to kill the entire program chain at the request
of the user's control-C.   Added EZdoc and now EZ TimberWolf comes packaged
with the root compressed tar file.
