the changelog vs. the stable 2.0.x series is below:

• Well over 2k commits since 2.0.0

The Big Ones:

• Add new automatic perspective correction module (" A new module for automatic perspective correction ")
• Liquify tool for all your fancy pixel moving (" Liquify, liquify? ")
• A new image module to use a Color Look Up Table (CLUT) to change colors in the image (" colour manipulation with the colour checker lut module ")
• In Highlight reconstruction module, the mode LCh reconstruction was completely rewritten, and is no longer useless!
• A new tool, darktable-chart, that goes along with the CLUT module, to create styles for the latter
• Exposure fusion in the basecurve module to lower the dynamic range of images (" compressing dynamic range with exposure fusion ")
• Add new raw overexposure indication (" Visualizing the raw (sensor) highlight clipping ")
• Darkroom: the preview (in top-left corner) is now no longer pre-demosaiced (but just downscaled without demosaicing it at the same time), thus the preview, color picker, histogram show the proper results, especially when there is highlight clipping.

Quite Interesting Changes:

• Split the database into a library containing images and a general one with styles, presets and tags. That allows having access to those when for example running with a :memory: library
• Support running on platforms other than x86 (64bit little-endian, currently ARM64 only) (" Running on non-x86 platforms ")
• darktable is now happy to use smaller stack sizes (no less than 256Kb). That should allow using musl libc
• Allow darktable-cli to work on directories
• Allow to import/export tags from Lightroom keyword files
• Allow using modifier keys to modify the step for sliders and curves. Defaults: Ctrl – x0.1; Shift – x10
• Allow using the [keyboard] cursor keys to interact with sliders, comboboxes and curves; modifiers apply too
• Support presets in “more modules” so you can quickly switch between your favorite sets of modules shown in the GUI
• Add range operator and date compare to the collection module
• Add basic undo/redo support for the darkroom (masks are not accounted !)
• Support the Exif date and time when importing photos from camera
• Input color profile module, when profile is just matrix (and linear curve), is 1/3 faster now.
• Rudimentary CYGM and RGBE color filter array support
• Nicer web gallery exporter – now touch friendly!
• OpenCL implementation of VNG/VNG4 demosaicing methods
• OpenCL implementation of Markesteijn demosaicing method for X-Trans sensors
• Filter-out some useless EXIF tags when exporting, helps keep EXIF size under ~64Kb
• OpenCL: properly discard CPU-based OpenCL devices. Fixes crashes on startup with some partially-working OpenCL implementations like pocl.
• darktable-cli: do not even try to open display, we don’t need it.
• Hotpixels module: make it actually work for X-Trans
• Cmstest tool should now produce correct output in more cases, especially in multi-monitor setups.
• Darkroom histogram now uses more bins: use all 8-bit of the output, not just 6.

Some More Changes, Probably Not Complete:

• Drop darktable-viewer tool in favor of slideshow view
• Remove gnome keyring password backend, use libsecret instead
• When using libsecret to store passwords then put them into the correct collection
• Hint via window manager when import/export is done
• Quick tagging searches anywhere, not just at the start of tags
• The sidecar XMP schema for history entries is now more consistent and less error prone
• Rawspeed: fixes for building with libjpeg (as opposed to libjpeg-turbo)
• Give the choice of equidistant and proportional feathering when using elliptical masks (shift+click)
• Add geolocation to watermark variables
• Fix some crashes with missing configured ICC profiles
• Support greyscale color profiles
• Make sure that proper signal handlers are still set after GM initialization…
• OSX: add trash support (thanks to Michael Kefeder for initial patch)
• Attach Xmp data to EXR files
• Several fixes for HighDPI displays
• Use Pango for text layout, thus supporting RTL languages
• Feathering size in some mask shapes can be set with shift+scroll
• Many bugs got fixed and some memory leaks plugged
• The usermanual was updated to reflect the changes in the 2.2 series
• Tone curve: mode “automatic in XYZ” mode for “scale chroma”
• Some compilation fixes

Lua specific changes:

• All asynchronous calls have been rewritten
• The darktable-specific implementation of yield was removed
• darktable.control.execute allows to execute some shell commands without blocking Lua
• darktable.control.read allows to wait for a file to be readable without blocking Lua
• darktable.control.sleep allows to pause the Lua execution without blocking other Lua threads
• darktable.gui.libs.metadata_view.register_info allows to add new field to the metadata widget in the darkroom view
• The TextView widget can now be created in Lua, allowing input of large chunks of text
• It is now possible to use a custom widget in the Lua preference window to configure a preference
• It is now possible to set the precision and step on slider widgets

Changed Dependencies:

• CMake 3.0 is now required.
• In order to compile darktable you now need at least gcc-4.7+/clang-3.3+, but better use gcc-5.0+
• Drop support for OS X 10.6
• Bump required libexiv2 version up to 0.24
• Bump GTK+ requirement to gtk-3.14. (because even Debian stable has it)
• Bump GLib requirement to glib-2.40.
• Port to OpenJPEG2
• SDL is no longer needed.
