- Update to 3.8.1:
* [Feature] 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).
The measurement window may be subject to desktop-wide color
management in upcoming versions of Wayland (although the
display device is inhibited during measurements via the
org.freedesktop.ColorManager.Device[1] D-Bus API which should
prevent this, and as a fallback a linear calibration sRGB
profile is temporarily installed during measurements if the
D-BUs API is unavailable, which should result in an identity
transform, i.e. effectively no color management, as well as
linear video card gamma tables).
Application support for color management under Wayland via
colord still seems to lacking[2] (although the list may well be
out-of-date).
Only tested under GNOME 3 (Fedora 30, Ubuntu 19.04). Support
for other desktop environments will need to be implemented
separately until Wayland gains a color management and
calibration/profiling protocol.

#application-support
* [Feature] LG OLED 3D LUT format.
* [Enhancement] If the currently used ArgyllCMS version is not a
standard version, but also not a beta, do not offer to switch
to an installed official stable version if it's otherwise the
same version number.
* [Enhancement] Include Quantum Dot LED (Samsung QLED Q9F)
spectral sample colorimeter correction when importing for i1
Display Pro and ColorMunki Display (sourced from community
colorimeter corrections database).
* [UI] (Debian, Fedora, Ubuntu) Use wxPython Phoenix if
installed.
* Prisma, Resolve: Set pattern generator background color to
pattern color if using fullscreen patterns.
* [Moderate] UnicodeDecodeError when a CCSS file contains unicode
characters in the display device description (regression of a
change in DisplayCAL 3.8 to use localized technology
descriptions, SVN revision r5810).
* [Minor] APL calculation for Prisma and Resolve pattern
generators was off by a few percent depending on pattern area
and current pattern color.
* [Minor] Quick reporting on calibrated or uncalibrated display
did not try to detect output levels if set to “Auto”.
* [Trivial] More gracefully deal with faulty tags in ICC profiles
(fixes ICC profile information unhandled exception for colord-
created profiles with malformed targ tags).
* [Trivial] [UI] Correctly update the audio button state on
progress dialogs when changed on a previous window.
* [Cosmetic] [UI] Various minor potential rendering glitches.
* [Cosmetic] [UI] Add work-arounds for various Wayland-related
wxPython rendering quirks and bugs (e.g. spacing around
windows, popup menu placement).
* [Trivial] Try to work around sporadic colord profile
installation quirks (“The profile was not added in time”).
