CURRENT RELEASE:

WhAEM2000 version 3.2.0 was released June, 2005.  This document lists known
deficiencies in version 3.2.0 as well as the changes between each of the
previous releases.  Contact the EPA project officer for details on bug fixes.

-----------------------------------------------------------------------------

KNOWN DEFICIENCIES IN VERSION 3.2.0:

1. WhAEM2000 does not support International representations of commas as
decimal points. The work around for European users is to set Windows to use
the American decimal mode in the control panels.

-----------------------------------------------------------------------------

CHANGES BETWEEN VERSIONS 3.1.1 and 3.2.0:

1.  A utility was added for editing shapefiles under View > Basemaps > Vector Graphics.  The user can choose a single color or they can choose an attribute field which specifies how a particular shape file is colored. The user my also select any number of attribute fields (contained in the shape file) to display as labels.


-----------------------------------------------------------------------------

CHANGES BETWEEN VERSIONS 2.1.0 and 3.1.1:

1. Raster graphics, such as USGS Digital Raster Graphics files (DRGs) in the
GeoTIFF format are now supported as basemaps.  A utility is available for
converting USGS Digital Orthophoto Quads (DOQ) into GeoTIFF format.

2. Simple WHPAs are now available as a Tool.  The simple WHPAs include
arbitrary/calculated fixed radius, asymmetric CFR, and well in uniform flow.

-----------------------------------------------------------------------------

CHANGES BETWEEN VERSIONS 2.0.4 beta and 2.1.0:

1. The Tool basemap browser was expanded to have web and CD-ROM access to EPA
supplied binary basemaps.

2. The Tools convert and export are now ESRI shapefile compatible.

3. The solver GFLOW1 has been updated (Oct 20, 2002).

4. The base map viewer has been updated to fill in blue for major surface
water features, and the potential viewing of elevation values associated with
hypsography BBMs has been added (although the hypso maps are currently
available on the CEAM Webserver for Ohio and Nebraska only).

-----------------------------------------------------------------------------

CHANGES BETWEEN VERSIONS 2.0.3 AND 2.0.4 beta:

1. The copy to clip board option in the results table has been fixed.

-----------------------------------------------------------------------------

CHANGES BETWEEN VERSIONS 2.0.2 AND 2.0.3 beta:

1. The Tool export to DXF was updated, adding tic marks on tracelines.

2. The Tool convert CAD to BBM was tested and updated.

-----------------------------------------------------------------------------

CHANGES BETWEEN VERSIONS 2.0.1 AND 2.0.2:

1. The conversion tool for SDTS to BBM has been updated to correct for bugs
in routine SDTS2BBM.

2. The conversion tool for DLG to BBM has been updated to correct for bugs in
routine BLDDLG. 

-----------------------------------------------------------------------------

CHANGES BETWEEN VERSIONS 1.0.5 AND 2.0.1:

1. New solution engine GFLOW1, and therefore slightly different data entry
windows.

-----------------------------------------------------------------------------

CHANGES BETWEEN VERSIONS 1.0.4 AND 1.0.5:

1. The conversion tool from DXF to BBM has been updated to include recent dxf
and dwg formats.  This tool is still not robust.

2. A warning is now given during creation of a project to recognize that
basemaps using USGS DLG, including all the bbm files downloaded from the EPA
Web server, have distance units in feet, and the user should not attempt
to change to feet. 

-----------------------------------------------------------------------------

CHANGES BETWEEN VERSIONS 1.0.3 AND 1.0.4:

1. Updated WhAEM2000 GUI file conversion utility to recognize the variety of
USGS DLG file formats (Tools > Convert > DLG to Basemap/SDTS to Basemap).

2. Updated WhAEM2000 GUI to allow for multiple selection of BBM files
(Project > Base Map Settings > Add BBM).

3. Corrected deficiency of the WhAEM2000 GUI in recognizing project
workspaces with long names or spaces in the path.

-----------------------------------------------------------------------------

CHANGES BETWEEN VERSIONS 0.0.0 AND 1.0.3:

1. First release through CEAM.
