 	New features and extensions
   
-	- added full support of true subwindows to the Mac OS X FLTK platform.
+	- Added full support of true subwindows to the Mac OS X platform.
 	  Window nesting to any depth is possible. An Fl_Gl_Window window or
 	  subwindow can contain Fl_Window's as subwindows.
 
 	Other improvements
 
-	- The Mac OS X FLTK platform no longer uses the deprecated AGL
-	  (Apple GL library) to draw openGL data. Instead, it uses standard cocoa
-	  APIs. This allows FLTK to support drawing GL scenes at high resolution
-	  when an Fl_Gl_Window is mapped to a 'retina' display.

 	- fl_read_image() now captures all pixels within the rectangle
 	  described by its arguments, whether they belong to a GL scene
 	  or not (STR #3142). It also captures subwindows of GL windows.
 	- Fl::delete_widget() now hides the widget or window immediately
 	  (i.e. when called) - only destruction is delayed as before.
+
+	Bug fixes
+
 	- Reading of .pbm image files is fixed: 1 is now interpreted as
 	  black, and images of width a multiple of 8 are correctly read.
+	  Note: if you relied on the faulty behavior you may need to fix
+	  your image files.
+	- Restored window background drawing, particularly the 'plastic'
+	  scheme's background (STR #3059). This was a regression since
+	  FLTK 1.3.0.
