5/1/1008: Updated StepperBoard active-x system and TestSerialPorts application to further improve scanning speed when a modem is detected on a com port (it rapidly skips that port, instead of retesting 8 times at differing baud rates).  This same update is in the SimplexCNC install; however, aside from updating the TestSerialPorts application, there are no updates for SimplexCNC itself.  Also, the entire source example tree (script files sources to StepperBoard, and so on) have now been switched over to a new version control system (subversion).  As a result, all sources have new date stamps, even though most have not been modified.
	4/19/2008: Updated StepperBoard class library and TestSerialPorts application based on the new class library update.  Patched issue related only to SD4DP product -- if the product is connected to your computer, but powered off, TestSerialPorts could hang until the SD4DP is either unplugged or powered.
	4/17/2008: Updated log file generation within the StepperBoard class library to generate Unicode based log files.  This allows non-Ascii messages (such as Chinese character sets) to be logged, if needed.  Recompiled TestSerialPorts with the new class library.  Also, updated SimplexCNC beta to correct an issue on soft limits.
	4/9/2008: Another update to SimplexCNC to add detection of user-generated divide-by-0 errors in the GCode scripting language
	4/6/2008: Updated SimplexCNC for edge conditions in range testing
	3/21/2008: Corrected typo in UniversalStepperBistepA06, UniversalStepperSS0705, UniversalStepperBS0610G and UniversalStepperSS0805 wherein incorrect jumper 'SS' is mentioned where 'JS' is meant (in section describing the "IO" connector).  Also, added new FTDI drivers (version 2.4.6) for communications with our USB based products.
	3/20/2008: Added notes in RelayStepper and PotStepper manuals to describe use on one of our newer surface mount boards.
	2/15/2008: First public beta release of the SimplexCNC application.
	2/14/2008: Updated all manuals (pdf documents) to make use of Adobe bookmarks, for easier navigation.  No information content was changed, so the main downloads page does not show this update for each manual.
	2/13/2008: Adjusted auto-scan code in the StepperBoard VB6 library to include an active wait for all serial data to be sent before it purges input data.  Also, added the Beta release of the FTDI USB drivers (which may be updated again next month).  Updated TestSerialPorts to make use of the updated StepperBoard library.
	1/23/2008: Updated installation packages to include the Beta Visual Studio .NET code by default, as opposed to being required to use a custom installation in order to get the sources.
	12/12/2007: Updated SD4DNCRouter and SD4DFifoNCStepper manuals to fix typos.
	11/27/2007: Adjusted TestSerialPorts application to attempt to automatically adjust FTDI USB latency settings if they are incorrect on a port associated with a StepperBoard product.
	11/25/2007: Added some simple USB diagnostics to detect and report key FTDI USB settings.  The diagnostics also contain the ability to change the USB settings to permit correct StepperBoard product operation.  These diagnostics need to be run as an administrator for correct operation.
	11/20/2007: Updated StepperBoard class library for improved detection of USB products.  Also includes updated TestSerialPorts application, which uses the same library.
	11/1/2007: Updated UniversalStepperSS0705.pdf manual to include notes on the SS0710USB board.  Correctly PotStepper.pdf manual to remove incorrect reference to 'e' command, and to include notes on the SS0710USB board.
	10/29/2007: Minor update to .NET beta; removed unneeded class from hierarchy.
	10/19/2007: Added the new .NET 2.0 version of the StepperBoard class library to the sample applications installer (which is also included in the full installer).  This code is early beta, and is not yet ready for production systems! It is being released now as an early test, for customer review and comments.  It does work to the extent that the sample code all compiles and runs; however, the sample code does not test all features of the system.  Use at your own risk!  It may only be installed from the sample applications installer through use of a 'custom installation'.   Full installation will NOT install this early beta.
	10/16/2007: Corrected 3 errors in StepperBoard class library.  BC2D15NCStepper and UCNCStepper firmware adjustments to be able to send separate currents to each motor, NCStepper4D adjustment to remove possible race condition on IdleWait function.
	10/10/2007: Corrected error in StepperBoard class library in the BC2D15NCStepper firmware support class; used the wrong command to update the extended IO bits.  Also, updated the BC4D15NCRouter and BC4D15PotRouter manuals to correct notes about the use of the XSI and XSO signals.
	10/8/2007: Updated StepperBoard class library to permit use of the extended step-and-direction modes which have recently been added to many of our firmwares.

	9/17/2007: Updated PotStepper4D and NCStepper4D manuals to document new SS4D artwork changes.
	9/10/2007: Updated the installation start-menu, to include a 'Manuals Organized by Product' tree.  This is a reversion to our tree prior to Vista in appearance, with the addition of an 'All Manuals' selection for easy Vista access.  This update ONLY adjusts the start-menu; there are no code or documentation changes.
	9/7/2007: Updated TestSerialPorts application sample to use correct 'GetSaveFileName' API, to force a '.log' file extension if none is specified, and to delete the existing log file (with confirmation) if a new one is selected and it already exists.
	8/14/2007: Updated StepperBoard class library to be better behaved on auto-parsing of values when in non-verbose modes of communication.
	7/23/2007: Updated TestSerialPorts for improved error detection, added new NCStepper4D reference, updated StepperBoard class libraries to include NCStepper4D.

	4/6/2007: Created the new SetUpFTDIStepperBoard installation application, to allow customers to obtain our version of the FTDI drivers for  our USB  boards.  This version contains the FTDI drivers version 2.00.00, and are intended for use under Microsoft® Windows® Vista® , XP®  and 2000®. The only difference between these drivers and the ones from FTDI is that their installation configuration files have been modified to reflect our unique USB address range, and to understand our timing requirements.  Due to the unique USB address, this file contains the version of the drivers which you must use with our products.
	4/1/2007: Updated the StepperBoard active-x system to support the SD4DPGenIO firmware as installed on the SD4DP step-and-direction board (support for this firmware is to be found in the SerRoute class).
	3/24/2007: Updated the StepperBoard active-x system to automatically detect attempts to open COM ports above port 9, and to adjust the port name to match Windows UNC requirements when this is done.  Also, adjusted the TestSerialPorts to use the same technique.  Prior versions of these tools would not automatically find any com ports above port number 9!
	3/21/2007: Vista Version!  This involves adjustments to almost all of our manuals, and a complete rewrite of our installation application.  We now install our code into "Program Files\StepperBoard", our sample code into "My Documents\StepperBoard", and our start menu now uses "StepperBoard' instead of "UniversalStepper" as the base of its tree.  Please uninstall your prior code from us (via the add/remove programs menu, under "UniversalStepper" before installing this update.
	3/9/2007: Updated StepperBoard class libraries and documentation for Vista compatibility.  SetUpCD no longer will permit installation of the retired BiStepCom active-X system under Vista, since BiStepCom will crash Vista.  Updated TestSerialPorts for Vista compatibility.  Updated VBScript sample code installed into the "UniversalStepper" directory as part of running SetUpCD  to use the StepperBoard active-x library instead of BiStepCom (again, for Vista compatibility).
