Crashes, corrupted images, and strange glitches have dogged Darktable users on both Windows and Linux for months. That ends now. The 5.6.2 update zeroes in on the worst bugs, bringing long-awaited stability to the open-source RAW editor.

OpenCL input gamma-corrected scaling was a major headache. It caused unpredictable results on some devices. That's fixed. Users with recent Intel drivers will see smoother performance. The Filmic RGB module also gets a fix. It no longer creates bad masks that could ruin an entire edit.

The 5.6.2 release also introduces white-balance presets for the Leica SL3-P (DNG) and Sony Alpha 7R VI (ILCE-7RM6), expanding support for photographers using these cameras.

Windows stability and usability overhaul

Windows users get the biggest boost. Darktable 5.6.2 wipes out a string of stubborn crashes and freezes. Many were caused by broken custom ONNX Runtime libraries. Another fix stops Darktable from stealing focus and keyboard input from other apps during file operations or when hovering over Lighttable thumbnails. Even Alt+Tab failures, once triggered by pointer placement over thumbnails, are gone.

External command handling on Windows is now cleaner. Instead of popping up a new console window every time Darktable or a Lua script runs an external command, the app keeps a single console session for the whole run. On Windows 11 24H2 and newer, there's no console window at all. The workflow is smoother. Distractions are gone.

Crashes, memory leaks, and Lua scripting fixes

Other platforms see fixes too. Neural Restore no longer fails at the end of RAW denoising on certain sensor sizes. Tile-seam blending used to write past image boundaries. That's patched. Another critical fix stops corrupted output or app crashes when AI models return more data than Darktable expects. This bug hit both object masks and Lua-based models. Importing broken styles with empty module orders is now safe. No more crashes there.

The 5.6.2 update is described as a maintenance and bug-fix release for the 5.6 stable branch, focusing on stability rather than introducing new features. It addresses crash corrections, OpenCL issues, and Windows usability problems, according to LinuxCompatible.

Memory leaks got attention too. The team plugged small leaks that happened during big import or export jobs and when pasting history stacks in Darkroom. Lua scripting is more reliable now. The script manager starts only once. User-installed script updates run from the right directory. The user's luarc file always loads.

Camera support and documentation updates

Camera support is mostly unchanged from 5.6.1. No new models get base support. But white balance presets are now available for the Leica SL3-P (DNG) and Sony ILCE-7RM6. Documentation versioning is back. The stable Darktable 5.6 manual is now separate from development docs, with a version switcher for easy access.

Upgrading from the 5.4 series? Your edits are safe, but the new library and config files won't work with Darktable 5.4. The developers urge users to back up before upgrading. Don't skip this step.

Darktable 5.6.2 is out for Linux, Windows, and macOS. Official AppImage builds are available for x86_64 and AArch64 Linux. According to a detailed Tweakers report, the Linux package includes SHA-256 checksums for download verification. That keeps downloads safe. This release is all about stability and a better user experience, especially for Windows users who have faced constant crashes. The team's focus is clear. They fixed real-world problems instead of chasing new features. That's what serious photographers need.
