dispcalGUI Portable full changelog

Cosmetic UI Improve PCS to device gamut outline plot.

Enhancement: Show the instrument serial number (if available) when prompting to physically interact with the instrument.
Enhancement: Check SpyderX dark offset calibration and abort if it is too high (user error).
Enhancement: Adjust perceptual device to PCS table black point to match perceptual PCS to device table.
Enhancement: Warn during automatic output levels detection if the display device input range or graphics driver output range look to be misconfigured.
Enhancement: Profile loader (Windows): Use an alternate method to enforce single instance if local IPC is blocked.
Tone response curve plot now uses the illuminant-relative profile whitepoint instead of D50 for input values if using absolute colorimetric intent.
Rename “LG OLED” (.dcl) 3D LUT format to “DeviceControl” and unlock available resolutions.

Linux: Preliminary experimental Wayland support under GNOME 3 using colord (requires ArgyllCMS 2.1 or newer as well). Caveats do apply:
Window placement and ordering is completely up to the compositor under Wayland. There is generally no way for an application to place its own windows at specific relative locations or z-orders. As a result of this, the measurement window cannot stay always on top or be automatically centered. Extra care needs to be taken that other windows are not placed on top.
Video card gamma table (videoLUT) access is handled by colord. Some functions like viewing current videoLUT contents may not be available.
The measurement window color depth is limited to 8 bits per channel per pixel (but dithering is used to achieve a higher effective color depth).

ENHANCEMENT Measurement report: Updated Fogra Media Wedge V3 evaluation criteria to ISO 12647-7:2016 version of the standard (use ?E*00 and ?Ch for CMY gray).
ENHANCEMENT Measurement report: Moved ?ICtCp to general evaluation criteria so it can be shown in the additional statistics for all available criteria.
ENHANCEMENT Updated simplified chinese translation (thanks to Mars).
ENHANCEMENT Full field pattern insertion: Support the latest ArgyllCMS 2.0.2 Beta development code.
ENHANCEMENT UI Consistency: When changing the verification chart, set the simulate whitepoint relative to display profile whitepoint option according to the simulation profile (just as when changing the simuation profile itself) and don't reset the simulate whitepoint option when changing the simulation profile.
COSMETIC Automatically fall back to the default verification chart if the selected one no longer exists (due to the chart file having been moved or deleted).

Added in this release:
Unique icons for all standalone tools.
Profile information can plot and display colors from named color profiles (including ICC v4).
Testchart editor, “Add reference patches”: Named color profiles can be used as reference.
Changed in this release:
Error handling: Omit traceback from error messages for filesystem and operating system related errors (like disk full or no read permissions on a file) as such errors are not code-related.
Updated french translation
If a profile is corrupted, show the curves window regardless if enabled. Show the profile error message only when the corrupted profile is first accessed, not each time the curves window is shown/hidden.
Testchart editor, “Add reference patches” (dealing with image colorspaces): Support Lab TIFF images. Fail on colorspace mismatches.
Removed DCI_P3.icm profile (prefer SMPTE431_P3.icm which is part of recent Argyll CMS releases).

Added in this release:
A new option to not use the video card gamma table to apply calibration (default like in 1.5.2.5/1.5.3.1: On for madVR, off for everything else).
Correlated color temperature, gamma, RGB gray balance and gamut graphs to measurement report.
Re-added the default testchart for gamma + matrix profiles.
Testchart editor: Dark region emphasis controls (Argyll CMS 1.6.2).
Testchart editor: Black patches amount control (Argyll CMS 1.6).
Testchart editor: Ability to add saturation sweeps and reference patches (from CGATS or images) to a testchart if using a preconditioning profile and adaptation = 100%.
Standalone curve viewer. This allows to view the curves of the currently assigned display profile or the actual video card gamma table without launching dispcalGUI.
Curve viewer can reload, apply black point compensation to, load into the videocard, and export calibration files.

Fixed possible unicode error in logging module.
Fixed a bug with optimizing a testchart for untethered measurements halving the amount of different device combinations by repeating patches if the total patch count was even.
New feature: When creating a profile from existing measurement data, averaging of measurements can be performed by selecting multiple files.
