 - Exposure fusion in the basecurve module to lower the dynamic range of images (https://www.darktable.org/2016/08/compressing-dynamic-range-with-exposure-fusion/)
 - Add new raw overexposure indication (https://www.darktable.org/2016/10/raw-overexposed/)
 - 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 undo/redo support for the darkroom
 
 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) (https://www.darktable.org/2016/04/running-on-non-x86-platforms/)
-- darktable is now happy to use smaller stack sizes. That should allow using musl libc
+- darktable is now happy to use smaller stack sizes (no less than 256Kb). That should allow using musl libc

 - 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 !)
