 The whole issue pushed Ell to implement multi-threading within GIMP, so
 that painting and display are now run on separate threads, thus greatly
 speeding up feedback of the graphical interface.

+## Improvements in handling masks, channels, and selections
+
+GIMP doesn't do any gamma conversion when converting between selection,
+channels, and masks anymore. This makes the selection -> channel -> selection
+roundtrips correct anbd predictable.
+
+Additionally, for all >8-bit per channel images, GIMP now uses linear color
+space for channels.
