Build 104 (available March 2009)
---------

--enhance HydroCalc Cross Section Plot window (January 2009)
A general channel cross sectin 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 modifiying inital 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" commands (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)
