Darktable photography workflow application and RAW developer released new stable 4.6.1 yesterday!

The release finished the documentation for the new 4.6 release series, include translations to Ukrainian, Polish and Dutch.

And, it now performs image discovery asynchronously in the import dialog. Meaning that long parsing due to huge number of sub-directories and
files can be easily interrupted by selecting another place or un-checking recursive mode.

The release now drops support for macOS versions older than 12.5. Other changes are mostly bug-fixes. They include:

Fix memory and resource leaks in the QOI image loader.
Fix RGBE image loader.
Fix crashes when running low on GPU or system memory.
Fix OpenCL startup for various cards.
Fix compatibility issues with HDR created DNG files.

Darktable is easy to install as Snap package, which runs in sandbox, using Ubuntu Software (or App Center for 23.10).

Option 2: Official deb package

The developer team offers official RPM and DEB packages for Debian, Fedora, Ubuntu, openSUSE, through the OBS building repository.

Also, ~~it’s NOT updated to v4.6.0 at the moment of writing~~. Keep an eye on this page if you prefer the official package.

Option 3: Flatpak package

Darktable is also available to install as Flatpak package, another universal Linux package format runs in sandbox!

While, Ubuntu user can open terminal (Ctrl+Alt+T) and run the 2 commands below one by one to install the Flatpak:

Enable flatpak support:
```

Install Darktable as Flatpak package:

Option 4: Ubuntu PPA

Besides using the official DEB package (See Option 2), I’ve also upload the package into this unofficial PPA for Ubuntu 22.04, Ubuntu 23.04, and Ubuntu 23.10.

sudo apt install darktable

In addition for old Ubuntu 20.04, 18.04, & 16.04, keep an eye on this PPA. However, it has tons of updated libraries that MAY run into dependency hell and/or package conflict!
