DisplayCAL 3.6 released

• [Feature] Adjustable weighting between luminance and saturation
  preservation for HDR SMPTE 2084 3D LUTs with roll-off
  tonemapping.
• [Feature] Option to adjust the roll-off for HDR SMPTE 2084 3D
  LUTs with roll-off tonemapping when the mastering display peak
  luminance is below 10000 cd/m² (previous behavior with the
  introduction of BT.2390-2 was to always adjust, the new default
  behavior is don't adjust).
• [Enhancement] Improved HDR 3D LUT SMPTE 2084 roll-off
  tonemapping to eliminate possible over-darkening in rolled-off
  highlights due to luminance reduction related effects.
• [Enhancement] Removed HDR 3D LUT SMPTE 2084 roll-off
  tonemapping allowance for hue shifts in rolled-off highlights.
• [Enhancement] Increased HDR 3D LUT SMPTE 2084 default target
  peak luminance to 480 cd/m² (makes BT.2390 roll-off leave 0-100
  cd/m² alone).
• [Enhancement] Use extended model for HDR 3D LUT Hybrid-Log
  Gamma (HLG) display gamma adjustment described in BT.2390-4.
• [Enhancement] Do not create PCS-to-device tables for synthetic
  HDR SMPTE 2084 profiles with roll-off tonemapping as they are
  meant purely as source profiles.
• [Enhancement] Only enable the visual whitepoint editor button
  if the whitepoint target is set to chromaticity coordinates.
• [UI] Keep dropdowns with only one choice enabled.
• [Cosmetic] Catch any madTPG connection errors to show a nicer
  error dialog without a traceback.
• [Trivial] Do not update the profile description when increasing
  the effective resolution of an existing profile's PCS-to-device
  tables.
• [Trivial] Testchart editor: Only limit the view to six decimal
  digits, not the underlying data.
• [Minor] Confirm instrument placement when madTPG is not
  fullscreen.
• [Minor] Creating synthetic grayscale profiles with HLG tone
  response did not work correctly.
• [Trivial] Set allowed filetypes for selecting files when
  importing 3rd party software colorimeter corrections to “any”.
• [UI] (GTK3 under Wayland)Explicit refresh/update needed for
  ClientDC (fixes graphs not updating until the window is
  resized).
