tiling: do not process uselessly small end tiles.OpenCL: a few fixes in profiled denoise, demosaic and colormapping.EXIF: properly handle image orientation '2' and '4' (swap them).When using wayland, prefer XWayland, because native Wayland support is not fully functional yet.It used to report some wrong name for some cameras. Fix crash in Lua libs when collapsing libs.cmstest: fix crash when missing XRandR extension.tools: A script to watch a folder for new images.tools: Add script to purge stale thumbnails.Better brush trace handing of opacity to get better control.bauhaus: when using soft bounds, keep slider step constant.Clear DerivedFrom from XMP before writing it.When appending EXIF data to an exported image, do not fail if reading of EXIF from the original file fails.

All Exif data is read and written using libexiv2. darktable uses both xmp sidecar files as well as its fast database for saving metadata and processing settings.darktable allows you to export to low dynamic range (jpg, png, tiff), 16-bit (ppm, tiff), or linear high dynamic range (pfm, exr) images. The powerful export system supports picasa webalbum, flickr upload, disk storage, 1:1 copy, email attachments and can generate a simple html-based web gallery.darktable currently comes with 15 translations: albanian, catalan, czech, dutch, finnish, french, gaelic, german, italian, japanese, polish, russian, spanish, swedish and thai.darktable has a zero-latency fullscreen, zoomable user interface through multi-level software caches.Import a variety of standard, raw and high dynamic range image formats (e.g.Filtering and sorting your collections within the base query or simple tagging by related tags are useful tools in your every-day photo workflow. A collect plugin allows you to execute flexible database queries, search your images by tags, image rating (stars), color labels and many more.

It offers GPU acceleration via OpenCL (runtime detection and enabling) and has built-in ICC profile support: sRGB, Adobe RGB, XYZ and linear RGB.

All darktable core functions operate on 4x32-bit floating point pixel buffers, enabling SSE instructions for speedups.
