2.11.3:

Gtk:
* Action: Added create_menu().
* CellRendererProgress: Added pulse, text-xalign, and 
  text-yalign properties.
  (Murray Cumming)
* DragContext::get_targets(), SelectionData::get_targets():
  Use the correct intermediate return type, to correct memory 
  management problems. This technically breaks ABI of these two 
  functions, but we believe that it was impossible to use them before, 
  so no applications should be broken by this improvement.
  (Murray Cummng, Daniel Elstner) Bug #399403 (Yannick Guesnet)
* EntryCompletion: Added set_inline_selection() and 
  get_inline_selection(). 
  Added cursor_on_match signal, though without a default signal 
  handlers, to preserve ABI.
  Added inline-selection property.
* Notebook: Added const versions of get_n_pages() and page_num(), 
  deprecating the non-const methods. Bug #442284 (Tomasz Ostrowski).
* Printer: Added list_papers().
* Range: Added set_show_fill_level(), get_show_fill_level(),
  set_restrict_to_fill_level(), get_restrict_to_fill_level(), 
  set_fill_level(), get_fill_level().
  Added show-fill-level, restrict-to-fill-level, and 
  fill-level properties.
* RecentAction: Added class.
* ScaleButton: Added class.
* VolumeButton: Added class.
* Stock IDs: Added DISCARD, ORIENTATION_PORTRAIT, 
  ORIENTATION_LANDSCAPE, ORIENTATION_REVERSE_LANDSCAPE, 
  ORIENTATION_REVERSE_PORTRAIT, SELECT_ALL
