- Hazard measurement redesigned:
  * The calculation is now only available in Radiance and Irradiance measurement mode.
  * Settings for future measurements (left widget side) and the display of the measurement results (right side) are now independent
  * In Radiance mode, the set Fov must necessarily correspond to the Fov of the calibration file, otherwise measurement will not be carried out
  * The calculation and displayed values are based on the calibrated wavelength range of the selected measurement, no longer on the wavelength range of the currently connected device and also independent of the selected Calculation Range.

- "Measuring mode"-drop-down-list appears only in offline mode. With device connected, the mode is displayed inside the "Measurement" button.
- Hazard: settings in the widget have influence only on subsequent measurements (not on previous; nothing is recalculated if settings are changed)
- Hazard: Now, Hazard is not calculated if some Spectral Weighting Function is loaded (to avoid confusion with double-applied weighting functions). If that's a case, a notice about it is shown in the Hazard-widget.
- Hazard: Options->Table - if Hazard is checked, Calibration File is also checked and dimmed to make it impossible to unckeck it.

- Hazard: Maximum time in Retina Thermal Weak mode had no upper limit. -> fixed (now it is 28800 seconds = 8 hours, after what it gets the value of PositiveInfinity)

- Saving of a calibration to device didn't always work with boudrate=3000000. -> fixed

- Export of Sync.-frequency into the table and into the Excel.
- After exporting an Excel table, option to open the target directory.
- "Target"-button in the calibration panel.

- Batch operations with large amounts of data and the table are optimized: instead of allocating small memory blocks many times, one large block is allocated etc.; instead of adding always 1 column to the table, many columns are added with one operation. This increases the speed much: for example, it is possible to transfer 65000 measurements to the table within a reasonable time.
- Calculations of CRI and CQS values were performed for spectra with 5 nm step which consisted of every 5th value of original measured spectra (because calculations are defined for 5 nm step via standards). Now the spectra for CRI and CQS calculation consist of averages of 5 values of original spectra. This improves stability of calculation results.
