We’re proud to announce the new bug-fix release of darktable, 5.2.1!

The github release is here: https://github.com/darktable-org/darktable/releases/tag/release-5.2.1.

To build from source, do not use the autogenerated tarball provided by GitHub on the release page, download our tar.xz file instead. If you're just building for yourself without creating a package for some distribution, then using source code cloning in git is an even more convenient way.

The Big Ones

The following is a summary of the main features added to darktable 5.2. Please see the user manual for more details of the individual changes (where available).

• N/A

UI/UX Improvements

• Reset window position if it can't be placed at last used position on any available monitor in a multi-monitor setup.

Performance Improvements

• N/A

Other Changes

• Add busy cursor while generating a GPX track preview and a progress bar while applying positions from a track to images.

Bug Fixes

• Fixed translation of snapshot module's labels.

• Expanded width of preference boxes Lua Options so that long input is visible.

• Fixed compilation when OpenMP is disabled.

• Fixed an OpenCL bug in rastermask module for non-raw images.

• Fixed regression introduced in darktable 5.0 with inability to read raw files from ancient (over two decades old) Canon cameras that recorded raw files with .tiff extension.

• Fixed the inability of external raster masks module to work in Windows with PFM files that have Unicode characters in the file name.

• Fixed a bug in liquify OpenCL code leading to incorrect clamped output.

• Fix color equalizer picker not working in quick access panel.

• Paletted TIFFs were read incorrectly by the main libtiff-based loader, with loss of color information. We are now handing them over to the GraphicsMagick/ImageMagick fallback loader (usually available in official/distro builds) for correct reading.

• The variable names for the metadata tags variables have been changed to the full case sensitive tag name to avoid ambiguity.

• Fixed inability to remove collections with ' in the name.

Lua

API Version

• API version is now 9.5.0

New Features

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 module's preference options.
