I also notice that there is a bug in V1.1.0 for matrix input
profiles where the correct white point value is not being written
(this bug was introduced in adding support for the XYZ cLUT
display + matrix profile type).

How incorrect is this for 1.1.0 generated profiles?

The cLUT data is transformed to be white point relative,
but the white point tag gets D50 written to it instead of
the actual white point.

So you won't notice unless you invoke absolute colorimetric,
at which point the errors could be large. (This only applies
to input matrix profiles that don't use the -u flag).

Any plans for a 1.1.1 release yet?

Soon I think, to catch up on the bugs.
