The Big Ones

The following is a summary of the main features added to darktable 4.8. Please see the user manual for more details of the individual changes (where available).

• n/a

Performance Improvements

• n/a

Other Changes

• n/a

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.

Lua

API Version

• API version is now 9.3.0

Bug Fixes

Add action support for Lua

Other Lua changes

• n/a

Notes

• Exporting with up-scaling and whithout using the high quality option will result in corrupt images.

• When exporting to AVIF, EXR, JPEG XL, or XCF, selecting specific metadata (e.g. geo-tag or creator) is not currently possible. For AVIF, EXR, JPEG XL, and XCF formats, darktable will not include any metadata fields unless the user selects all of the checkboxes in the export module's preference options.

• In order to support the correct display of numbers in darktable, the minimum supported Gtk version has had to be increased to 3.24.15. For people who need to build darktable with an older version, this can be achieved by removing line 241 of the darktable.css file on your system. See  #13166.

• Release 4.8 drops support for macOS versions older than 13.5.
