Yesterday I have finally merged the
linear_gamma branch into the
stable one. This means that all recent developments will be incorporated in the packages provided by PPAs, AUR and the like. From now on, the
linear_gamma branch will not be further updated.
The merged changes are focusing mainly on the accurate processing of RGB images in linear gamma encoding, as well as floating-point HDR images. Clipping of channel values has been avoided wherever possible, and new tools like the
tone mapping curves have been introduced to provide some simple highlights compression for HDR images.
Another important change is the support for DCP profiles in the RAW development module. Such profiles allow, among other things, to approximately match the vendor-specific look of in-camera Jpegs (by using for example those included in the free Adobe DNG converter package).
Updated binary packages for Linux (in AppImage format), OSX and Windows 64bits are automatically created and made available here.
