+## CIE xyY support
+
+Thanks to Elle Stone, GIMP now features initial support for color readouts
+in the CIE xyY color space. You can see these values in the *Info* window
+of the **Color Picker** tool and in the *Sample Points* dock.
+
+Much like CIE LAB, this color space is a derivative of CIE XYZ. The *Y* channel
+separates luminance information from chromaticity information in the *x* and
+*y* channels. You might be (unknowingly) familiar with this color space if you
+ever looked at a [horshoe diagram of an ICC 
profile](https://ninedegreesbelow.com/photography/all-the-colors.html).

+CIE xyY is useful to explore varios color-related topics like the
+[Abney effect](https://en.wikipedia.org/wiki/Abney_effect). See

+for an example of what people do with this kind of information.

 ## Around GIMP
-### GEGL
+### GEGL and babl
+
+The babl library got an important fix that directly affects GIMP users:
+the color of transparent pixels is now preserved during conversion
+to premultiplied alpha. This means all transform and deformation operations
+now maintain color for fully transparent pixels, making unerase and curves
+manipulation of alpha channel more reliable.
 
-Øyvind Kolås has been working on doing [multispectral/hyperspectral processing
-in GEGL](https://www.patreon.com/posts/camayakaa-float-22446330), GIMP's
-graphics engine, which happens to be the groundwork for CMYK processing.
+On the GEGL side, a new buffer iterator API was added (GIMP code has been
+ported to this improved interface as well). Additionally, new GEGL_TILE_COPY
+command was added to backends to make buffer duplication/copies more efficient.

 an internal source told us that there have been over 214,000 downloads of GIMP

 Flathub is a new kind of application repository for GNU/Linux, so of
 course these numbers are not representative of all downloads.
 In particular, we don't have statistics for Windows and macOS.
 Even for Linux, every distribution out there makes its own package of GIMP.
