+User Interface:
+
+  - Dark theme: improve accessibility of GtkRadioButton by adding a
+    white border on mouse-hover.
+  - Gray theme: set light background for selected text in Layers and
+    Paths dockable dialogs to make text visible.
+  - Dark, Gray and Light themes: remove 3D shadow box around eye and
+    link toggles in Layers, Channels, and Paths dockable dialog tree

     * Support for planar configuration.
     * Support for deprecated big endian transfer.

+    * Thumbnail storing now done by storing the thumbnail as the second
+      page in the file (through Exiv2) and setting metadata
+      "Exif.Thumbnail.NewSubfileType" to 1 (reduced resolution image)
+      instead of storing the thumbnail as a subifd. This was done
+      because of a Windows bug locking TIFF files with thumbnail stored
+      as subfid.
+    * Symmetrically, loading will ignore pages marked as "reduced
+      resolution image" (i.e. it will consider them as thumbnails), as
+      well as try to guess if a page (without subfile type) is a
+      thumbnail when it meets following criteria: second page with YCbCr
+      PhotometricInterpretation, old style jpeg compression while the
+      first page has a different PhotometricInterpretation or
+      compression.
 
 Script-fu:
 
   - New (dir-make "/dir/name" mode) function to create a directory.
