2.8.10:

* UIManager: Fix crash when built without exceptions support.
  (Johannes Schmid)
* Build:
  - Omit the atkmm dependency from the gtkmm pkg-config .pc file 
  when atkmm was optionally disabled. (Rémi Cardona) 
  Bug #366930 from John N. Laliberte.
  - Added --enable-api-maemo-extensions configure option, 
  to optionally provide C++ wrappers for the additional GtkTextBuffer 
  functions in the Maemo version of GTK+.
