#######################################################
Build 105 (available April 2010)
---------
--enhance HydroCalc General Cross Section Input (June 2009)
Allow general cross section input file to be space, comma, or tab delimited (add regsub command to Input.tcl).
Build 104 (available March 2009)
---------
--enhance HydroCalc Cross Section Plot window (January 2009)
A general channel cross section can now be viewed in an undistorted (1:1) or distorted scale (using a slider bar).
--added Manning friction formulation to PipeCalc (December 2008)
Full-flow pipe computations can now be performed utilizing the Manning Equation to characterize the friction loss.
--added Elliptical channel to HydroCalc (June 2008)
HydroCalc can now perform computations for an elliptical channel cross section.
--corrected HydroCalc problem (12/12/08)
Alleviate "divide by zero" error for general channel normal depth computations by modifying initial guesses to Secant Algorithm.
--corrected HydroCalc problem (8/04/08)
Saving a rating curve could cause an error if the channel became "full" before reaching the max rating curve flow. This problem has been alleviated.
Build 103 (available May 2008)
---------
--corrected PipeCalc error (4/25/08)
Darcy --> Size: calculations did not work, corrected error in function call argument
--corrected SedCalc problem (4/15/08)
Ackers-White: removed potential blow-up problem when Ds >> 60
--SedCalc improved input error checking
Build 102 (available April 2008)
---------
--corrected SedCalc error (3/24/08)
Yang Eq: Vcr expression had a syntax error, for Rs >=70
--add more extensive input parameter checking (catch more input errors)
--internally convert all real input values to double precision
--add curly braces around all math "expr" ccomands (internal Tcl syntax issue, increases computational speed and reduces potential substitution errors)
Build 101 (available February 2008)
---------
--corrected SedCalc error (1/22/08):
Meyer-Peter-Mueller Eq and Van Rijn Bed Load Eq: For English Units calculation, d90 was inadvertently set to d50.
--GeoCalc: add ASCII Save Results capability (1/25/08)
--minor bug fixes
--add more extensive input parameter checking (catch more input errors)
Build 100 (available November 2007)
---------
--1st Freeware version on website
--"ManCalc --> Help --> SpecificInfo" link was not active (fixed, 1/8/08)
