 New Stuff:
+   - Added a thread safe shared pointer object

      API and also changed the dlib thread pool so that it no longer causes
      a terminating program to wait for any outstanding threads to finish
      before allowing the application to end.
+   - Changed the serialization format of the linearly_independent_subset_finder
+     class.
+   - Changed all the font pointers in the gui API's interfaces
+     to shared_ptr_thread_safe objects.
 
 Bug fixes:
+   - Made the kkmeans class actually use the min_change parameter.
+   - Fixed a bug in the linearly_independent_subset_finder object.  Also
+     added a way to set a minimum tolerance.  
+   - Fixed a bug in the scrollable_region widget that caused it to scroll in an
+     unpleasant way when the horizontal and vertical scroll increments weren't 
+     set to the same value.
+   - Made one of the arguments to font::draw_string() not be a reference because
+     some versions of gcc don't end up doing the right thing when -O3 is 
+     supplied.
+   - Fixed a bug in the covariance() function that prevented it from compiling
+     sometimes.
 
 Other:
+   - Changed the gui core code around so that it should be safe to make window 
+     objects at the global scope.
+   - Added more control over how the scrollable_region scrolls its region.
+     You can now adjust how much it scrolls when the mouse wheel is scrolled 
+     as well as enabling scrolling via a mouse drag.
+   - Modified the library so that it compiles with the Intel compiler.
+   - Added some example programs that use the relevance vector machine
