SusProg3D - Suspension by Design.
===================

Windows 7, Windows 8, Windows 10

Version 4.660G (Build 1258.6)

Updates and fixes in this release.
=================================
V4.660G (Build 1258.6)
Fixed a bug in the spring, shock, arb suspension input form that displayed incorrect text.

V4.660F (Build 1258.5)
Fixed a bug in the server licence registration that ignored the entered port number.
Fixed a bug in the network client that erroneously reported a registered client as unregistered.
Added the functionality to allow entering vehicle coordinates for axle mounted shock and spring.
Fixed a bug that displayed an incorrect axis character in some input forms.

V4.660E (Build 1254.4)
Fixed a bug with the steering calculations when using [Upright].
Fixed a bug with the roll calculations if there was zero bump travel.
Added an error check for invalid shock lengths if they were used to set suspension travel.
Fixed a bug with showing steering tab items when there was no steering.
Updated the ECalc and VCalc to show more meaningful error messages.

V4.660C (Build 1253.2)
Fixed a bug with the live axle 4-link suspension.
Added better error handling for excessive turning angle with lateral drag link steering.

V4.660B (Build 1252.1)
Updated the roll&bump calculations to include static.

V4.660A (Build 1252.0)
Extensive changes to the live axle calculations for performance.
Reduced the number of live axle calculation options.

V4.650A (Build 1243.0)
Added the speedway style front transverse torsion bar suspension.
Deleted the "Scale" parameter. For scale models, premultiply all dimensions by the scale factor.

V4.640B (Build 1233.1)
Updated the Excel exports "Roll" values to include sign. Positive values are LH roll, negative values are RH roll.
Updated to the latest Delphi 10.3.1 Rio compiler.

V4.640A (Build 1233.0)
Added an option to the Panhard rod to allow for connecting to the axle or to a birdcage.
Added the speedway style rear suspension, using a Winters torque tube axle, 4 links, birdcages and Jacobs ladder.
Updated to the latest Delphi 10.3.0 Rio compiler.

V4.630C (Build 1193.2)
In the Roll&Bump config, if the maximum roll isn't an integer multiple of the display, then the last roll may exceed the maximum roll. Fixed.
If showing the IC trace, the RH roll trace is not shown correctly. Fixed.
When exporting the calculated roll&bump values to Excel, without also doing the steering calculations, some of the droop values are not exported. Fixed.

V4.630B (Build 1190.1)
Double clicking on a data file now always loads the correct file.
The intermediate link steering now allows the intermediate link arm to extend opposite to the Pitman and idler arms.
The chassis pivot Mumford linkage now allows for
1) the bellcrank and lever pivot axes P2 can be offset laterally and vertically,
2) the bellcrank and lever pivot axes can be different lengths,
3) the bellcrank and lever chassis pivots P1 can be non-symmetrical
The axle pivot Mumford linkage is still restricted to
1) the bellcrank and lever pivot axes P2 must have zero lateral and vertical offsets,
2) the bellcrank and lever pivot axes can be different lengths,
2) the bellcrank and lever chassis pivots P1 can be non-symmetrical, but must have the same longitudinal dimension

V4.630A (Build 1184.0)
Minor updates to the recirculating ball type steering Pitman and idler arm descriptions.
Extended the Mumford linkage to include axle mounted bellcrank and lever.
Added an error message if the rear ride height reference point is forward of the front ride height reference point.
Excel 2016 (V16.0) now correctly identified.

V4.620C (Build 1173.2)
If the roll and/or bump increments are zero, then default them to the max bump or max droop.
If the Pitman arm and/or idler arm axis is tilted (in front view) the steering calculations can fail.

V4.620B (Build 1168.1)
Added the roll direction for Dynamic calculations.

V4.620A (Build 1166.0)
Added an option to the 4-link live axle to have a birdcage linkage on one side.

V4.610B (Build 1161.1)
Fixed a bug when eCalc is used, cycling through the steering calculation options doesn't work correctly.

V4.610A (Build 1159.0)
Fixed the download link in the About box.
Refactored the Excel import and export code and corrected a number of bugs.
Added strut data to the Excel import and export.
Updated the Excel help file documentation.
Fixed a memory allocation bug.
Fixed an issue that caused the rates calculation to fail if the steering calculation had not been done, or raised an error.
Fixed a bug that sometimes caused the spring wire diameter to become very small.
Changed the spring symmetry test to exclude the position of the spring platform.
Fixed the torsion bar windup angle calculations.
Fixed a bug that caused the torsion bar class to increment with successive calculations.
Updated to the latest Delphi 10.2.3 Tokyo compiler.
Fixed a bug with the chassis caster link mount for Ford Mustang.

V4.605A (Build 1137.0)
Fixed a bug in Sawdust that prevented updating the number of licences.
Refactored the Excel import and export code and corrected a number of bugs.
Added the error logging to all Excel tools.
For metric data, added the functionality to handle "inch size" wheel data.
Updated the Excel help file documentation.

V4.600E (Build 1131.4)
Fixed a bug that prevented setting the chassis camber link mount for Ford Mustang.

V4.600D (Build 1131.3)
Opening a data file with live axle sometimes fails if the toe setting is non-zero.

V4.600C (Build 1131.2)
Opening a data file sometimes fails if the TotalMass is zero.

V4.600B (Build 1131.1)
Opening a data file fails if the roll calculation start is using a "bump" point.

V4.600A (Build 1131.0)
If the wheel toe setting option is changed, any open dialogs will now be updated with the new setting.
If the angle setting option is changed, any open dialogs will now be updated with the new setting.
Added the front wheel steering to the display.
Removed the hard limits on the number of bump & droop calculations.
Removed the hard limit on the number of roll calculations, and now roll in both directions.
Changed the Ackermann calculations to use toe-out-in-turn instead of using the steering arm intersection.
Added Ackermann percentage to the Excel exports.
Added steering offset to both steering calculations and Excel exports.
Added an option to limit the Excel ranges.
Added the pushrod/pullrod to bellcrank angle, shock to bellcrank angle to the suspension calculations, and added them to the Excel exports.
