dispcalGUI 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).

Ability to create 3D LUTs in PNG (Portable Network Graphic) and ReShade format. The latter allows fully color managed Direct3D (8–11.2) and OpenGL applications (e.g. games) under Windows (Vista and higher).
“Apply calibration (vcgt)” to 3D LUT tab as advanced option, as well as a warning when installing a 3D LUT with applied calibration for a display with non-linear videocard gamma tables.
Option to enable/disable the 3D LUT tab.

Curve viewer and profile information: Detect more known tone response curves.
Colorimetric observer choice as advanced calibration option for instruments that support it (i.e. spectrometers as well as i1 Display Pro, ColorMunki Display and Spyder 4/5).

Instrument first-time setup (i.e. importing colorimeter corrections) will now automatically run when it hasn't been run before.

Tabbed user interface
Full support for Argyll CMS 1.7.0, which includes support for the ColorHug2, K-10A, Spyder5, the capability to use a Google Chromecast as pattern generator, and more. Note that the accuracy of using a ChromeCast is limited due to the internal RGB to YCbCr conversion and upscaling in the device.

Scripting support (locally and over the network).
Possibilty to do spectrometer self-calibration on its own (look in the “Options” menu). Useful in conjunction with “Allow to skip spectrometer self-calibration”.

Added in this release:
Argyll CMS 1.7 beta compatibility: Klein K10-A support (requires Argyll CMS 1.7 beta test 2014-05-21 or newer) and updated technology strings for colorimeter correction creation. When creating 3D LUTs with Rec. 1886 or custom tone response curve, force RGB source 0 0 0 to map to RGB destination 0 0 0 (requires Argyll CMS 1.7 beta development code 2014-07-10 or newer).
Enable black output offset instead of all-input offset for 3D LUTs, measurement report and synthetic profile creation (based on Argyll CMS 1.7 beta development code 2014-07-12, thanks to Graeme Gill). Note that for 3D LUTs, if using output offset ideally Argyll CMS 1.7 should be used aswell once it becomes available since the current implementation in dispcalGUI that enables output offset when used with Argyll CMS 1.6.3 or older has limited 16-bit precision for the black point mapping (due to the implementation altering the source profile TRC on-the-fly in that case
