We're proud to announce the new feature release of darktable, 4.6.0!

The github release is here: https://github.com/darktable-org/darktable/releases/tag/release-4.6.0.

As always, please don't use the autogenerated tarball provided by github, but only our tar.xz file. The checksums are:

$ sha256sum darktable-4.6.0.tar.xz
??? darktable-4.6.0.tar.xz

When updating from the stable 4.2.x series, please bear in mind that your edits will be preserved during this process, but the new library and configuration will no longer be usable with 4.2.x.

You are strongly advised to take a backup first.

The Big Ones

The following is a summary of the main features added to darktable 4.6. Please see the user manual for more details of the individual changes (where available).

Performance Improvements

One of the major highlights of this release is the number of performance improvements and enhancements:

Other Changes

  • Hotpixels module now also supports monochrome images.

  • Retouch module do not need the internal guide widget, so it has been removed.

  • Allow import session to be canceled by clicking on the cross in the progress bar on bottom left.

  • Add support for auto orientation when importing AVIF/HEIF images (requires at least libavif 0.9.2 and/or libheif 1.16.0).

Bug Fixes

  • Fixes OpenCL platform checking which could lead to a freeze of darktable.

Lua

API Version

  • API version is now 9.2.0

Add action support for Lua

Other Lua changes

  • Allow access to image change_timestamp.

Notes

  • 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 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 darktable-org#13166.

  • Starting with release 4.4 a new support policy regarding macOS versions has been put in place -- darktable releases will now only support those macOS versions that are also supported by Apple. Release 4.6 therefore drops support for macOS versions older than 11.3.
