    when moving to a frequency with no sources. Also: Camera/"Add to source phi" with arbitrary angle replaces "Add 180° to phi"
    and a note added to Camera dialog indicates that "Untilt" and "Add to source phi" do not affect Display when Show is set to BF SPL. Finally, use of an ROI on the Display is disabled when Show is set to Sources and either Camera is a Radar view or either
    "Add to source phi" or "Untilt" is nonzero.
    7.033: 9/9/2025 Spectra log and JSON include Display pixel indices of sources. Spectra log can be shown in SPL view.

    3.033: 6/4/2017 Reformatted checkboxes in Settings dialog.
    3.032: 6/3/2017 Bug fixes: Choosing Track RPM (in Engine order mode) now causes a track operation right away.
    Corrected an error in conventional beamforming (i.e., not selecting OptiNav BF) that caused the
    levels to be too low and altered the resolution of the conventional beamform map.
    3.031: 5/27/2017 Restores Display ROI behavior to version 3: no effect on beamforming unless "Limit to ROI" is selected
    Change was needed because active ROI in versions 3.02 and 3.03 was interfering with Inhibit and Partition modes.

    The Display, Spectrogram, and Spectrum windows can be resized by dragging the corners.
    The scroll bars on the Control dialog are more visible on Windows 10.
    The Control dialog has a new button "ROIs" that opens the ROIs dialog giving many ways to specify and edit several ROIs.
    The Control dialog also has checkbox "ROI mode". Selecting this causes the Display to show a single
    SPL value for each ROI. These values are also listed in results tables (title either "Peak list" or "Roi integrals")
    2.15: 3/25/2017 Replaced "Diagonal Optimization" with "Noise reduction mode." Should be faster and better.
    2.14: 2/22/2017 Fixed bug that sometimes caused extra spots at 270°, 0° and 90° in fisheye view.

    2.091: 11/21/2016 Removed a diagnostic print that is not shown anyway. Probably unimportant change.
    2.09: 11/20/2016 Redefines the Sharper button to be more robust with multiple sources. This mode
    compromises level accuracy to achieve higher resolution. Only functions when OptiNav
    beamforming is selected. Can give very low levels with tones.
    2.08: 11/17/2016 Improved calculation for OptiNav Beamforming: better resolution and stability.
    2.07: 9/20/2016 Separate dialog for camera parameters. Includes option for image reflections.
    Sound gain setting value in dB shown. Now it also affects .mp4 output videos.
    New dialog for Air Properties (temperature and, for wind tunnel, Mach No.)
    Error reporting when trying to read invalid binary log file. 2.06: 8/28/2016 Two new optical parameters: "Field of View Magnification Factor" (suggest 1.4 or 3)
    and "Undistortion Factor" (suggest 1.2)
    Access by selecting "Show camera optical parameters in Settings" on the startup dialog.
