DisplayCAL 3.8.8.0 + Portable

Changed in this release:
Enhancement Detect and warn about malformed colorimeter corrections (e.g. from non-official sources). Move them to the trash automatically if they were previously (manually) installed.
Enhancement Always enumerate instruments on application startup if more than one instrument was detected the last time the application was used (cross-platform consistency).
Enhancement When prompting for instrument calibration, display the just now detected instrument name instead of the previously enumerated name (the latter might be stale if you forgot to refresh after changing connected instruments).
Enhancement Use a slightly improved smoothing method when creating high resolution PCS to device tables.
Enhancement Increase automatic PCS to device table resolution for L*a*b* LUT profiles to 45x45x45 if using smoothing.
Enhancement UI Only auto-close profile/3D LUT installation dialog after a successful installation.
Enhancement Don't auto-close madTPG after 3D LUT installation.
Enhancement macOS: Warn if a black luminance calibration target is set.
Enhancement Profile loader (Windows): Use a minimally faster method to check for other running applications.
Fixed in this release:
Minor madVR 3D LUT generation: Always write D65 white to 3D LUT input primaries metadata so madVR does not attempt to correct whitepoint differences on its own when using a custom whitepoint (the 3D LUT itself will map the custom whitepoint correctly).
Minor madVR 3D LUT installation: Don't attempt to install 3D LUTs with unsupported input primaries metadata (i.e. not Rec. 709, SMPTE C, EBU/PAL, Rec. 2020 or DCI P3) as madVR will overwrite the metadata depending on the 3D LUT install slot. Such 3D LUTs should only be assigned manually in madVR instead.
Trivial UI When loading settings, always enable the 3D LUT tab if the display is virtual (consistent with display selection behavior).
Trivial Also apply black point correction when creating a matrix profile without black point compensation (consistency).
Trivial Do not create swapped matrix fallback tags for XYZ LUT profiles when using the alternate forward profiler and the used ArgyllCMS version is >= 2.1 (be consistent with ArgyllCMS).
Trivial madVR 3D LUT generation: Accept negative values for input primaries metadata.
Trivial madVR 3D LUT installation (Linux, macOS): Send the 3D LUT in chunks and increase the timeout to prevent the installation failing over a slow network (e.g. WiFi).
Cosmetic UI Profile loader (Windows): Prevent a stale tray icon remaining (until mouse over) in some rare cases after exiting the profile loader.
Trivial Profile loader (Windows 7): Skip incomplete display configuration registry entries.

Enhancement If the graphics drivers or hardware do not support loadable gamma ramps or calibration, show a more descriptive error message.
Enhancement Increase the timeout for display & instrument detection during application startup from 10 to 20 seconds, to allow for slow opening of legacy serial ports.
Enhancement Windows 10 1903: Always do instrument detection during application startup if more than one instrument was connected the last time the application was used, as the list of instruments is not guaranteed to be consistent between sessions under 1903.
Enhancement Profile loader (Windows): Apply smoothing to calibration if the quantization bitdepth is set to 8.
Enhancement Profile loader (Windows): No longer require running elevated to be able to detect changes in the display configuration under Windows 10 1903.
Fixed in this release:
Minor Do not attempt to access properties of non-existent objects if a subprocess is not succesfully terminated after reaching a timeout during display & instrument detection at application startup (unexpected failure).
Trivial UI Disable the profile installation button if no displays have been detected.
Trivial UI Disable the measurement report menu item if no instruments have been detected.
Trivial Profile loader (Windows): Work around Windows 10 1903 handle leaks in Windows Color System APIs.
