- 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.

* 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.
