数字摄影暗房软件 Darktable 2.2.0 发布了。这个版本包括新的自动透视校正模块，一个用于所有你喜欢的像素移动的液化工具，一个使用颜色查找表（CLUT）来改变图像中颜色的新图像模块，等等。主要更新如下：
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) (https://www.darktable.org/2016/04/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
