  This includes HBox, VBox, HButtonBox, VButtonBox, HPaned, VPaned, HScale, 
  VScale,  HSeparator, VSeparator, HScrollbar and VScrollbar.
  HBox and VBox are not protected by ifdefs because they are used as base 
  classes for several other widgets, and we can't change that without breaking 
  ABI.
* Dialog: Deprecate get_vbox(), replacing with get_content_area(), 
  to match the C function name.

3.0.1 (stable):

Gtk:

  (Murray Cumming)

gtkmm 3.0:

To port to gtkmm-3.0 you should first try to build your application with
gtkmm-2.4 but without using deprecated API. For instance:
http://www.murrayc.com/blog/permalink/2011/01/18/avoiding-use-of-deprecated-api/

The deprecated API generally has documentation suggesting what new API you
should use instead:
http://developer.gnome.org/gtkmm/2.24/deprecated.html

These hints might also be helpful:
http://live.gnome.org/gtkmm/PortingToGtkmm3

Some new/changed API in gtkmm-3.0:

Gtk:
* Adjustment is now used via RefPtr.
* AppChooser, AppChooserButton, AppChooserDialog.
* Box, ButtonBox, IconView, Paned, ProgressBar, ScaleButton, ScrollBar,
  and Separator now derive from Orientable.
* All widgets derive from Buildable.
* Several widgets derive from Scrollable.
* CellArea and CellAreaBox
* ComboBox now derives from CellLayout.
* IconSet is now used via RefPtr.
* StyleContext, StyleProvider, and CssProvider, replacing Style and Rc.
* Grid
* NumerableIcon.
* Switch
* Widget::on_expose_event() is now Widget::on_draw().

Gdk:
* Added DeviceManager.
* Removed Drawable, Pixmap and Bitmap.
* Cursor is now used via RefPtr.
* RGBA replaces Color, though Color still exists because it is used by TextView.
  We hope to deprecated Color completely in gtkmm 3.2.
* Removed Colormap and its general awkardness.

General:
* Use std::vector in several methods instead of the intermediate *Handle types,
  to make the API clearer.
* Change all operator void* to operator const void*, with a BoolExpr typedef
  and extra documentation.
  This avoids an unintentional implicit cast to int, and is generally
  considered good practice in C++. The new C++ standard allows the use of
  the explicit keyword here instead, but that is not yet widespread.
* Many existing classes have many new methods.
* gtkmm-3.0 currently has no deprecated API.
  Not even API that was added and then deprecated during GTK+ 3.0.

See also the list of new API in gtkmm 3.0:
http://developer.gnome.org/gtkmm/unstable/since_3_0.html

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.

* Widget:
  - Added queue_draw_region(), set/get_hexpand(),
	set/get_hexpand_set(), set/get_vexpand(), set/get_vexpand_set(),
