You are strongly advised to take a backup first.

Performance Improvements

Other Changes

Bug Fixes

Fixed export without high quality sampling but with up-scaling activated.
Fixed support for all vectorscope modes when using CMYK profiles as for softproofing.
Fixed empty lighttable when importing from command-line. Now darktable opens lighttable on first filmroll when importing from command-line.
Fixed color picker area resizing using corners when heavy distorting is applied into image.
Fixed wrong cropping in rotate and perspective module with strong rotation and automatic cropping set to “original format”.
Fixed possible color shift (pink) when using the Retouch module with the embedded lens correction module.
Fixed histogram display when using a color picker area on a rotated or flipped image.
Fixed a crash while using the -d imageio option.
Fixed large image exports due to a bug in finalscale module.
