FLAC/Slope 4.00 Modification List  Choose "About" from "Help" menu to check version
number.)   FLAC/Slope version number corresponds to FLAC 4.00 version number.

    Date          Description

    12/16/02    Added Report option under [File]/[Make Report] menu
                item.   This creates a report as an HTML-formatted file which
                includes tables summarizing properties and model conditions,
                and factor-of-safety results.  The report also includes plots
                of factor of safety and failure surfaces.  Note that the HTML
                file may require excessive system memory if several model
                cases are included in the report.  This may cause the
                FLAC/Slope graphical window to freeze.   If this happens, try
                creating the report for only one case at a time or without
                plots.

              Official Release Version is FLAC/Slope 1.20.344 on 11A and 12A CD

    05/04/03    Added message, if model is cloned, to warn that material and
                cable properties are not cloned.  A change in these properties
                will affect results if original model is rerun.  It is better
                to create a new material for a cloned model if different
                properties are assigned.

    09/18/03    Modification to delete duplicated vertices when two tables
		coincide on a vertical slope.  Duplicate vertices were
		causing grid-generation errors
		Modification to suppress characters "/", "\" and ":" in the
		model name, which caused bad filenames.  Replaced by "_".

    10/08/03    Modification to tables made on 09/18/03 caused problem with
                creating a single boundary between two layers.  This is now
                corrected.

    01/15/04    Modification so that porosity set equal to 0.0 will be
                saved in project file.  By default, porosity was set to 0.5.

                Modification to prevent problem with calculating applied
                pressure if two points of water table are above the slope
                boundary.

    07-01-04    Modification to spinner buttons so that stepping is improverd
                for negative exponents.

    07/06/04    Change to automatic perimeter calculation for geosynthetic
                sheets.
                Previously, perimeter = 2 * sqrt(pi * area) which is same as
                single cable.
                Now, perimeter = 2 * (1.0 + thickness) for sheet and
                perimeter = 2 * sqrt(pi * area) for single cable.
                Note that this increases factor of safety calculation for
                example in Section 1.4.4 of FLAC/Slope User's Guide.
