5/18/07 Fixed bug that caused an exception to be thrown when right clicking on a chart with no data channels
enabled.
Added missing Tracking Cursor combobox menuitem to the "View|Chart|Tracking Cursor" menu.
Added "Apply Changes" menu item to the Tracking Cursor menus, and reworked their functionality.

09/08/08 to 10/31/08 Version 1.00 Release Notes.
- New Features................................................................
- Added more channels so that the total is now 48.  Customer request.
- Added choices for 1000, 2000, 4000, 8000, 16000, or 32000 data points.  Customer request.
- Modified charting and data logging so that Ambient can be charted/logged along with process.
   This is needed for the UWRH units, where customers want to plot temperature with RH.
- Added Offset Calibration to Channel Configuration.
- Added support for configuring MWTC and UWRH connectors.
- Added support for configuring MWTC-REC1 receivers.
- Added Japanese color codes to View menu for Channels display.
- Modified Configuration Wizards so that only USB serial ports are checked when connecting.
- Optimized connection code in Wizards so that establishing a link to a device happens more
   rapidly.
- Modified Wizards to show Device Model Number, Firmware version, and Wizard software version.
- Modified TRH Central to search only USB serial ports, reducing connect time at startup.
- Added code to detect insertion and removal of USB devices, so that the main program will
   report "No Connection" when the receiver USB plug is removed, and automatically re-
   connect when the same plug is re-inserted.
- Updated splash screen and about box to read "Omega TRH Central Products" instead of UWTC.

- Bug Fixes...................................................................
- Fixed bug that would not allow a saved data file to be loaded.
- Fixed bug that randomly caused the program to "freeze" or lock up on exit.
- Fixed bug that caused TRH Central to use 50% PC resources.

11/05/08 Version 1.00.11.05 Release Notes.
- New Features................................................................
- Added blinking --- to show open sensor for UWRH

- Bug Fixes...................................................................
- Fixed bug that displayed 999 for the sign-off code instead of blanking the 
   display.

11/20/08 Version 1.00.11.20 Release Notes.

09/04/27 Release Notes for Version 1.00.9.427 maintenance release
- Bug Fixes...................................................................
- Fixed bug that caused chart time labels to be incorrect when charting in
   "Continuous" mode, and the maximum number of data points have been plotted.
- Fixed bug that caused incorrect update of alarm settings when selecting
   units in Deg C.  (This was reported by a customer)
- Removed the radio buttons on the channel configuration dialog box and 
   replaced with a label that shows the currently selected "Temperature" 
   units.  Relative humidity and future products with pressure mV, etc. are 
   not affected by this change.  Temperature units are now selected from the
   main "Channels" tabs only.  This reduces confusion and prevents displaying
   readings in one temperature unit while having to choose between units
   when configuring alarm and/or offsets.
- Fixed bug that caused incorrect readings when an offset value is specified,
   and readings are being viewed in Deg C.

09/06/15 Release Notes for Version 1.00.9.615 maintenance release
- Bug Fixes...................................................................
- Fixed bug that caused process to not be displayed when TJ probes with
   firmware number 081215 attached.  New firmware has been written to
   respond to the PA command, which causes Ambient to be displayed.  Probes
   with firmware 081215 and older will not display Ambient, but will display
   process temperature with this version of TRHC.

- Fixed bug in the "Line Options" dialog box listbox where the selected line
   was not the same line as the one selected in the listbox.

09/07/22 Release Notes for Version 1.00.9.722 maintenance release
- Bug Fixes...................................................................
- Fixed bug that caused process and ambient to display incorrect values when
   the PC is configured for different languages.  Replaced all instances of
   the Visual Basic "Format" function with the DotNet "String.Format"
   function.

- Added option to save file as Tab Delimited.  This was originally a request
   for a new feature, but not having it causes errors with European
   language options.  It is now considered a bug fix.

07/24/09 Version 1.01.09.724 Release Notes.
- New Features................................................................
- Added support for UTC-USB.  Added configuration dialog box to send
   settings for MA Filter, IIR Filter, and TC Type.  The dialog box also
   allows setting MA and IIR Filters for the TJ-USB.

04/19/10 Version 1.02.10.0419 New Version Release Notes.
- New Features................................................................
- Added support for the PX409-USB Pressure Transducer.
- Added support for the IR-USB Infrared Temperature Sensor.
- Split left and right Y axes so that any process or ambient plot can be
   assigned to either Y axis.  The assignment is done via the start datalog
   dialog box.
- Added "Configure Axes" button and dialog box to allow the customer to
   customize the axis titles with either selected units or custom units, and 
   assign minimum and maximum axis limits for both left and right Y axes.

07/08/10 Release Notes for Version 1.02.10.708 maintenance release
- Bug Fixes...................................................................
- Fixed bug that caused process values in the data log to not convert to
   Deg C when the C button was pressed.

- Fixed bug that caused the left and right axis minimum and maximum values
   to not follow the minimum and maximum values entered in the Configure
   Axes dialog box, when changing units from F to C.

08/19/10 Release Notes for Version 1.02.10.0819 maintenance release
- Modifications...............................................................
- Modified the numeric format of the data log from fixed point, 1 decimal
  place to fixed point, with the number of decimal places determined by
  either the product ID code, or the response from the device for the 
  "DPLACES" command.  
  The new data log format is as follows:
	    TJ-USB-K1 - Fixed:  1
	    TJ-USB-K2 - Fixed:  0
	    UTC-USB - Fixed:  0
	    RH-USB - Fixed:  1
	    IR-USB - Fixed:  0
	    PX409-USB - Fixed:  0, 1, 2, or 3

- Modified the numeric format of the range values shown on the channel box
  from no decimal places (whole numbers only) to "general" format which only
  shows a decimal point when the number contains a non-zero value to the 
  right of the decimal point.  This is needed to accommodate the 
  0 to 2.5 PSI version of the PX409-USB.

09/07/10 Release Notes for Version 1.02.10.0907 maintenance release
- Bug Fixes...................................................................
- Fixed bug that caused duplicate readings in the data log.  The symptoms
  appear when using a TJ-USB, UTC-USB, or PX409-USB and logging data at the
  one second per sample rate.  The cause was due to the "Channel" readings
  taking slightly longer than one second to update the channel box, while the 
  "Log" timer reads the value in the channel box every second.  This was
  because the channel timer was suspended until all queried units responded,
  then restarted for another second.  After this bug fix, the channel timer
  no longer waits for a response from any unit, and is also set for 0.9 Sec.
  This ensures that there is always a "fresh" reading in the channel box each
  time the data logging function reads it.

09/10/10 Release Notes for Version 1.02.10.0910 maintenance release
- Bug Fixes...................................................................
- Fixed bug that caused an exception to be thrown when starting TRH Central
  with a device plugged in.  This exception only occured when all of the
  channel boxes have had a serial number assigned to them, and the new unit
  being connected has yet another serial number.  If all the channels have
  serial numbers assigned to them, the program now searches for the first
  channel that is not acitve.  If all channels are active, a message box is
  displayed alerting the user that the maximum number of devices are in use.

- Fixed bug that caused an exception to be thrown when starting a data logging
  session.  This exception only occured when one or more channel boxes had
  an empty description field.

09/27/11 Release Notes for Version 1.03.11.0927 maintenance release
- For PX409, added ability to display and log data in different engineering units:
PSI, in-Hg, in-H20, bar, mbar, and HPa.
- Added support for PX409 devices whose base units are units besides PSI.
- Streamlined units selection: for each device, units are changed from a single dropdown
in the channel box. This will change the display, chart, and logging units. When an 
acquisition begins, the chart/logging units lock, but the units displayed in the channel
box can be changed at any time.
- Changed internal settings format for better reliability and upgradeability.
NOTE: This version uses a new settings format. On first launch, the channel boxes will
be in their default state (alarms off, no scale or offset, etc.).
- Added "Check For Updates" selection to Help menu.
- Data acquisition uses less RAM.

2/24/12 Release Notes for Version 1.03.12.0224 maintenance release
- For PX409 devices, no longer do any filtering in software.  Certain combinations of device and
input gave undesirably slow response.  Firmware filtering can still be set with "Configure Device".
- Splash screen now displays full version number.
- Fixed display and unit conversion issue for in-H2O and in-Hg PX409-USB devices.
- Added more verbose error messages.

7/27/12 Release Notes for Version 1.03.12.0727 maintenance release
- Translate decimal separator (using System.Globalization.NumberFormatInfo.CurrentInfo.NumberDecimalseparator)
  when reading emissivity to avoid nasty crashing behavior in config dialog, since IR-USB always uses a period,
  but some parts of the world don't.
- Likewise, when writing value, if using a decimal separator other than a period, change to period before
  setting value, device doesn't like comma and will actually set wrong value.
- For PX-409 USB, update display of unit range to use correct decimal separator

9/4/12 Release Notes for Version 1.03.12.0904 maintenance release
- Per customer request, add new torr pressure unit and conversions
- Update Help | Online Manual to refer to common manual for all products, remove old UTC-USB manual link

4/11/13 Release Notes for Version 1.03.13.0411 maintenance release
- Update algorithm that extracts USB serial number from FTDI device, a non-Omega FTDI USB device with no serial number,
  which shouldn't happen, throws an exception with our algorithm

8/15/13 Release Notes for Version 1.03.13.0815 feature release
- Added support for PX409-USBH pressure sensors.
- Added new pressure engineering units: ft-H2O, mmHg, kPa
- Added boxcar filter configuration support.
- Pressure sensors will now default to the sensor's engineering units rather than PSI

09/19/13 Release Notes for Version 1.03.13.0913 maintenance release
- Application would occasionally crash when unplugging a device on certain systems.
