Some major improvements in this release, including the following:
Profiled denoising: adapt to the properties of your camera’s sensor (72 cameras already profiled for you).
Lightroom import: convert some basic edits from your lightroom collection to darktable operations.
Multi instance support: duplicate your modules and apply them more than one time with different settings.
improved usability for distorting modules (streamline spot removal in the presence of crop/rotate for example).
Conditional blending updates (colour popping).
Haven’t had time to test them all yet, it would appear that development is accelerating with new tools being made available at a faster rate than before, this software is becoming a major contender within its field!
