Version 2.3.1

• major usability upgrade: the GUI for setting up multi-device/multi-measurements uses now the "wizard" template and offers parameter sweeps, too
• feature: Data exporter classes can now also be loaded as addons. This is e.g. useful for uploading data to any kind of cloud or data anlysis pipeline.
• bugfix: Saved LiveViewer snapshot data was overwritten on disk leading to loss of data.
• bugfix: Measurement sweeps did not calculate the sweep vectors correctly in all cases.
• usability: much nicer Addon loading overview dialog
• usability: slight change to the schema of the saved measurement sweep summary - measurement settings can in any case be distinguished from metadata now
• under-the-hood: removing of old, deprecated code
• under-the-hood: update of dependencies due to safety reasons

Version 2.3.0

Released 2024-03-20

• major feature: measurement sweeps
  • the new measurement wizard now supports creating sweeps across single or multiple parameters
  • specifying the sweep for each parameter can either be in number of points (linear or logarithmically spaced) or in step size (linear spacing)
  • data generated by the sweeps get saved into their own subfolder in the raw output directory and include extra sweep information
  • a sweep overview file is also added for easier post-processing
• feature: InsertionLossSweep now supports loading a previously measured insertion loss sweep for a calibrated loss measurement
• feature: Chip manifest loading can now be extended to other formats by simply loading your custom classes as addons
• usability: a new settings window allows adjusting the amount of displayed ToDos and the amount of in-memory measurements - useful for long running experiments
• usability: repeating more than just the last measurement is now possible - LabExT will ask you how many older measurement should be repeated
• usability: chip names can be changed after every measurement (provided no manifest is loaded)
• usability: console logging now highlights warnings/errors with colors
• usability: finished measurement plot now spans whole main window
• usability: search for peak can now save parameters without triggering execution
• under-the-hood: complete rewrite of live-viewer for improved performance - if you have custom live viewer cards written, you will need to adapt to the new API
• under-the-hood: saved raw data files now indent with tabs - saves roughly 30% file size
• under-the-hood: update of dependencies due to safety reasons
• deprecation: LabExT does not support Python 3.8 anymore, please switch to Python 3.9 or 3.10
