 _Posterize_ and _Desaturate_ color tools have been converted to regular GEGL-based filters, and both _Tile_ 
and _Pagecurl_ filters have been converted to use GEGL buffers. A quite popular "photographic" _Highpass_

 A way more noticeable new feature, however, is split preview for GEGL-based filters. You can compare 
before/after versions right on canvas and move a "curtain" around to see more of "before" or "after" and swap

 ## darktable as RAW processing plugin
 
-On Linux, GIMP is now capable of using darktable for pre-processing raw images from DSLRs (Canon CR2, Nikon 
NEF etc.). darktable is an amazing project whose developers stick around at our IRC channel and even 
contribute to GIMP (most recently, they added reading various metadata from EXR files).

 ## Screenshots
 
 The code for capturing screenshots has undergone a major reorganization. It's now split into a back-end and 
several front-ends specific for Windows, OS X, Wayland and X.org (Linux and UNIX systems).
 
-While there are no immediate user-visible changes, this reorganizations greatly simplifies improving user 
experience for different operating systems.
