allows to pause the Lua execution without blocking other Lua threads.allows to wait for a file to be readable without blocking Lua.allows to execute some shell commands without blocking Lua.the darktable-specific implementation of yield was removed.

All asynchronous calls have been rewritten.Tone curve: mode “automatic in XYZ” mode for “scale chroma”.The usermanual was updated to reflect the changes in the 2.2 series.Many bugs got fixed and some memory leaks plugged.Feathering size in some mask shapes can be set with shift+scroll.Use Pango for text layout, thus supporting RTL languages.OSX: add trash support (thanks to Michael Kefeder for initial patch).Make sure that proper signal handlers are still set after GM initialization….Lens correction module: switched back to normal Lensfun search mode for lens lookups.Fix some crashes with missing configured ICC profiles.Give the choice of equidistant and proportional feathering when using elliptical masks (shift+click).Rawspeed: fixes for building with libjpeg (as opposed to libjpeg-turbo).The sidecar XMP schema for history entries is now more consistent and less error prone.Quick tagging searches anywhere, not just at the start of tags.Hint via window manager when import/export is done.When using libsecret to store passwords then put them into the correct collection.Remove gnome keyring password backend, use libsecret instead.Drop darktable-viewer tool in favor of slideshow view.#Some More Changes, Probably Not Complete: Darkroom histogram now uses more bins: use all 8-bit of the output, not just 6.Cmstest tool should now produce correct output in more cases, especially in multi-monitor setups.Hotpixels module: make it actually work for X-Trans.darktable-cli: do not even try to open display, we don’t need it.Fixes crashes on startup with some partially-working OpenCL implementations like pocl. OpenCL: properly discard CPU-based OpenCL devices.Filter-out some useless EXIF tags when exporting, helps keep EXIF size under ~64Kb.OpenCL implementation of Markesteijn demosaicing method for X-Trans sensors.OpenCL implementation of VNG/VNG4 demosaicing methods.Nicer web gallery exporter – now touch friendly!.Rudimentary CYGM and RGBE color filter array support.Input color profile module, when profile is just matrix (and linear curve), is 1/3 faster now.Support the Exif date and time when importing photos from camera.Add basic undo/redo support for the darkroom (masks are not accounted !).Add range operator and date compare to the collection module.Support presets in “more modules” so you can quickly switch between your favorite sets of modules shown in the GUI.Allow using the cursor keys to interact with sliders, comboboxes and curves modifiers apply too.Allow using modifier keys to modify the step for sliders and curves.

Allow to import/export tags from Lightroom keyword files.Allow darktable-cli to work on directories.darktable is now happy to use smaller stack sizes (no less than 256Kb).Support running on platforms other than x86 (64bit little-endian, currently ARM64 only) ( Running on non-x86 platforms | darktable).That allows having access to those when for example running with a :memory: library Split the database into a library containing images and a general one with styles, presets and tags.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.Add new raw overexposure indication ( Visualizing the raw (sensor) highlight clipping | darktable).Exposure fusion in the basecurve module to lower the dynamic range of images ( compressing dynamic range with exposure fusion | darktable).A new tool, darktable-chart, that goes along with the CLUT module, to create styles for the latter.In Highlight reconstruction module, the mode LCh reconstruction was completely rewritten, and is no longer useless!.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 | darktable).

Liquify tool for all your fancy pixel moving ( Liquify, liquify? | darktable).

Add new automatic perspective correction module ( A new module for automatic perspective correction | darktable).
