darktable 2.4 arrived last Christmas with numerous new features and improvements, and now users can update to darktable 2.4.1, a minor maintenance release adding support for new digital cameras, including the Panasonic DC-G9 (4:3), Paralenz Dive Camera, Pentax KP, and Sjcam SJ6 LEGEND. It also adds a new filter rule to the Collect module to allow users to more easily find locally copied images, enables blending and masking in the Hot Pixels module, adds a speed boost to the Grain module, implements a debug print when compiling OpenCL kernels, and supports stdout handling on Windows systems.
