# Changelog
## v1.2.1
Mostly bugfixes along with the occasional new feature.
- Calibration:
- File format changed to json
- Multiple measurements can be taken/deleted at the same time
- Calibration kit allows separate male/female standards
- configurable Z0 for short/open
- SCPI commands:
- load/save calibration files
- export to touchstone file format directly
- additional command for reading trace data
- fix typo in documentation
- UI improvements:
- Additional Y-axis options: Reactance/Real/Imaginary
- Graphs look a bit nicer
- Configurable line width for graphs
- finally added an application logo
- General bugfixes, among others:
- PLL divider calculation fixed for certain frequencies
- Improved USB buffer handling
- Better error handling when opening invalid files
- Various bugs when adding/deleting markers
- graph autoscaling with invisible traces
## v1.2.0
- Additional SCPI commands
