+2.91.6 (unstable):
+
+Gtk:
+* Added the StyleContext, StyleProvider, and CssProvider classes, 
+  removing the Style and RC classes.
+* Added Gdk::Cairo::set_source_rgba().
+* Widget: Added get_style_context().
+* Cellrenderer, Cellrenderertext, Cellview, Colorbutton, TextTag:
+  Added RGBA versions of color properties. We expect to remove Gdk::Color 
+  in future, maybe then renaming all uses of RGBA to Color.
+* ColorSelection: Added get/set_current_rgba() and get/set_previous_rgba().
+* ComboBoxText:
+  - Renamed append_text(), prepend_text() and insert_text() to append(), 
+  prepend() and insert().
+  - Added extra append()/prepend()/insert() overloads that also take an id.
+  - Added get/set_id_column(), get/set_active_id() and properties.
+* Widget:
+  - Removed the style_changed signal because it used GtkStyle, though 
+  we might bring this back when the GTK+ code is completely ported to 
+  GtkStyleContext.
+  - Added get_path(), removing path().
+  - Removed the no_expose_event signal.
+* Added WidgetPath.
+* Window: get_geometry(): Removed the depth parameter.
+
+Gdk:
+* Removed Drawable.
+* RGBA: Rename set_rgb_p(double) to set_rgba(dobule) and rename the old 
+  set_rgb(gushort) to set_rgb_u(gushort). Likewise for other methods. 
+  This makes it more like GdkRGBA, which uses double instead of the gushort 
+  that GdkColor used.
+* Window:
+  - Added set_background(RGBA) and renamed  set_background_pattern() to 
+  set_background(Pattern).
+	- Added set_clip_region() and get_visible_region() and create_cairo_context(),
+	which were previously in the (now removed) base Drawable class.

 2.91.5.1 (unstable):
