3.1.6 (unstable):

Gtk:
* All H* or V* specialized classes have been deprecated, to

  set the orientation instead.
  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:
* EntryCompletion: signal_cursor_match_info(): Fix this.
  (Murray Cumming) Noticed by Andrew E. Makeev.
* MessageDialog: Correct the get_message_area() return type.

* Fix the --enable-warnings=fatal build with GTK+ 3.1.x.
  (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

	(Armin Burgmeier)
	- set_window(), set_has_window(), and get_requisition() are now protected.
	(Murray Cumming)

	properly.
  (Kjell Ahlstedt) Bug #606903 (Hammered)

  that GdkColor used.

  This allows gtkmm-2.4 and gtkmm-3.0 to use the same atkmm ABI.
  (Daniel Elstner)

  (Murray Cumming)

2.90.0 (unstable):

* Renamed ABI from gtkmm-2.4 to gtkmm-3.0.
  This requires applications to change their pkg-config check to gtkmm-3.0
  when they wish to use gtkmm-3.0 instead of gtkmm 2.x.
* Use gtk+ 3.0 instead of gtk+ 2.0.
* Removed deprecated API.
* Remove support for these glibmm build options via ifdefs:
  --enable-api-exceptions
  --enable-api-properties
  --enable-api-default-signal-handlers
  (All this gtkmm API is now always present.)
* Added Border and used it in Entry and Range.
  (Krzesimir Nowak)
* FileChooser:
  Use std::string for filenames, instead of ustring, fixing bug #142138.
* Action, ActionGroup, ListStore, SizeGroup, TreeStore, Widget:
  Inherit and Implement Buildable.
* Button, EntryCompletion, MenuItem, RecentChooserMenu, ToolButton, ToolItem,
  IconView: Inherit and implement Activatable.
  TreeViewCOlumn,
* Box, ButtonBox, Paned, Ruler, ScaleButton, ScrollBar, Separator, SpinButton:
