* Updated product numbers for Signal Hound system polynomial calibration kits.
* Added SCPI commands for minimizing/maximizing the application window.
  - :DISPlay:MINimize
  - :DISPlay:MAXimize
* Bug fix: Fixed Mkr->Start/Stop/Center implementations.

- Software Version 1.0.9 (10/2/2025)
* Allow arbitrary frequency spacing for sNp files used in databased cal kits.
* Better auto scale behavior for LogMag and SWR trace formats.
* Added trace scale coupling.

  - Display hide

- Software Version 1.0.8 (8/26/2025)
* Traces now update during a calibration. After measuring a standard, traces associated with the channel being
  calibrated will update. This allows you to verify correct connections during calibration.
* Improved screenshots with option to omit control panels.
* Added new Signal Hound system calibration kit definitions.
* Added ability to import calibration kits.
* Added ability to export SNP data files from databased cal kit standards.
* Added SCPI commands for setting low pass time domain compatible settings.
  - :CALCulate<ch>:MEASure<tr>:TRANsform:TIME:SLPFrequency
  - :CALCulate<ch>:MEASure<tr>:TRANsform:TIME:SLPFrequency?
* Added preference for disabling the standard selection dialog when only one standard matches the class being measured.

- Software Version 1.0.7 (7/24/2025)
* Improved measurement accuracy when the calibration is interpolated across the hardware band breaks.
* Added SCPI commands for saving and loading instrument state.
  - :SYSTem:PRESet[:USER]:SAVE <filename>
  - :SYSTem:PRESet[:USER]:LOAD <filename>
* Bug fix: Fixed marker peak left.
* Bug fix: Markers should now update properly when changing measurement configurations.

- Software Version 1.0.6 (6/11/2025)
* Fixed "User Manual" file menu entry. Was not properly opening the user manual.

- Software Version 1.0.5 (5/12/2025)
* Added marker peak tracking and corresponding SCPI commands.
  - :SENSe<ch>:MEASure<tr>:MARKer<mkr>:FUNCtion:TRACking OFF|MAXimum
  - :SENSe<ch>:MEASure<tr>:MARKer<mkr>:FUNCtion:TRACking?
* When selecting a calibration kit,
  - The calibration kit selected now defaults to last used kit.
  - User calibration kits are now listed before system kits.
* When adding a new standard to a calibration kit, the corresponding class may optionally be automatically assigned to it.
* Improved UI feedback for:
  - Selecting traces on plot.
  - Performing automatic port extension measurements.

- Software Version 1.0.4 (4/9/2025)
* Official public release.

- Software Version 1.0.3 (2/25/2025)
* Added Ohm marker readout in the configuration
  - Time domain enabled
  - Lowpass step response selected
  - Trace format is real
* Minimum sweep size is now 1 point.
* Minimum step size is now 0Hz.
* Bug fix: Fixed impulse step response for time domain measurements when multiple extrapolated points are needed.
* Bug fix: Fixed marker coupling for Smith chart plots.
* Bug fix: Fixed marker coupling across channels with different stimulus.
* Bug fix: Time domain x-axis fixed for different transform types.
* Bug fix: Step size stimulus control now working properly.
