+Release notes for 2.20
+======================
+
+* GtkStatusbar now has a message area (see gtk_status_bar_get_message_area)
+ which makes it easy to place additional widgets inside the statusbar
+ frame or to replace the label widgets. Previously, this was only possible
+ by accessing the innards of the statusbar widget directly. Applications
+ which are doing so may need some adjustments, since the addition of the
+ message area changed the internal widget hierarchy.
+
+* GtkBuilder no longer sets the "name" property of widgets to the ID
+ attribute of the <object>. Use gtk_buildable_get_name() instead of
+ gtk_widget_get_name() to obtain the ID.
+
+* GTK+ now includes introspection data, as a consequence, it gained a
+ dependency on gobject-introspection. It is possible to build without
+ introspection by passing --disable-introspection to configure.
+
+
+Release notes for 2.18
+======================
+
+* gtk_tooltip_set_custom now accept a NULL custom_widget to unset the
+ old custom_widget. Custom_widget does not get destroyed when the
+ tooltip goes away.
+
+* JPEG2000 support is no longer enabled by default. It must be
+ explicitly turned on, by passing --with-libjasper to configure.
+
+* GDK has been reworked to implement 'client-side windows'. This offers
+ exciting new possibilities, such as transformed, offscreen rendering,
+ but it breaks some long-standing assumptions that applications may
+ have about GDK windows. Setting the environment variable
+ GDK_NATIVE_WINDOWS makes GDK create a native X11 window for each
+ GDK window, which might make problematic applications work better.
+
+* GTK+ calls signal (SIGPIPE, SIG_IGN) during initialization, to ignore
+ SIGPIPE signals, since these are almost never wanted in graphical
+ applications. If you do need to handle SIGPIPE for some reason, reset
+ the handler after gtk_init(), but notice that other libraries (e.g.
+ libdbus or gvfs) might do similar things.
+
+Release notes for 2.16
+======================
+
+* Password entries now display a caps-lock warning. This can be turned off
+ with the caps-lock-warning property.
+
+* Various orientation-related functions have been deprecated in favour
+ of the new GtkOrientable interface: gtk_scale_button_get_orientation,
+ gtk_scale_button_set_orientation, gtk_toolbar_set_orientation.
+
+* The action-proxy interaction has been changed. Widgets that operate as
+ proxies have to implement the GtkActivatable interface now. GtkActivatable
+ implementation are responsible for syncing their appearance with the
+ action and for activating the action. All GTK+ widgets that are commonly
+ used as proxies implement the GtkActivatable interface.
+
+* The handling of keyboard shortcuts has been changed, to help with a
+ longstanding complaint about the way GTK+ handles multiple layouts. GTK+
+ now only uses keys from groups other than the current group if they are
+ not present in the current group.
+
+Release notes for 2.14
+======================
+
+* gtkitemfactory.h is now completely deprecated.
+ As gtkactiongroup.h and gtkstock.h no longer include the gtkitemfactory.h
+ header, this might break application using gtk_item_factory_* symbols
+ without including gtkitemfactory.h - even though this behaviour has never
+ been supported in the first place.
+
+* The GtkFileSystem semi-private interface has been removed.
+ The GTK+ filechooser implementation now uses GIO directly, which has
+ rendered external filesystem implementations unnecessary. Consequently,
+ the GtkFileSystem interface is no longer available, nor the filechooser
+ will load any GtkFileSystem implementation.
+
+* GtkComboBox now renders the popdown button insensitive when
+ the model is empty. Applications which want to populate the list
+ only before displaying it can set gtk_combo_box_set_button_sensitivity
+ to GTK_SENSITIVITY_ON, so that the button is always sensitive or
+ GTK_SENSITIVITY_OFF to make it insensitive respectively.
+
+* GtkAdjustment now enforces that values are restricted to the
+ range [lower, upper - page_size]. This has always been the documented
+ behaviour, and the recommended practice is to set page_size to 0
+ when using adjustments for simple scalar values, like in a slider
+ or spin button.
+
+* gdk-pixbuf will use GIO for mime type detection if possible. For
+ this to work, shared-mime-info needs to be installed and XDG_DATA_DIRS
+ set accordingly at configure time. Otherwise, gdk-pixbuf falls
+ back to its built-in sniffing implementation.
+
Release notes for 2.12
======================
-* Functions: gtk_about_dialog_get/set_name() were deprecated in favour of
+* gtk_about_dialog_get/set_name() were deprecated in favour of
gtk_about_dialog_get/set_program_name(), the GtkAboutDialog now uses the
"program-name" property instead of the conflicting "name" property.
-* The tiff loader now requires libtiff 3.6.0 or later.
+* The gdk-pixbuf tiff loader now requires libtiff 3.6.0 or later.
* Support for Windows 9x/ME has officially been removed. It hasn't worked
since 2.6 anyway.
is called create-window, so this name can no longer be used for signals
in objects derived from GtkNotebook.
+* The gtk_notebook_set/get_group_id() functions were found to be insufficient
+ and have been deprecated in favour of gtk_notebook_set/get_group().
+
* The move-focus signal has been moved to GtkWidget, to unify the
various implementations of this signal in specific widgets. Great care
has been taken to make sure that all code using this signal continues
to work.
-* Removed an unused and hardly visible GtkFrame from the menu widget hierarchy
- when GtkComboBox::appears-as-list style property is set. Any RC file
- applying a different style to any widget below the widget path
- "gtk-combobox-popup-window.GtkFrame" should take into account that the
- frame no longer exists.
-
-* The external print preview application used by GtkPrintOperationPreview is
- now passed the print settings on the command line with the --print-settings
- parameter pointing to a temp file containing the settings. The preview
- application assumes ownership of the file and should delete it once it does
- not need it anymore. The --print-settings commandline option is understood
- by Evince 0.9.0 and newer. To use a different print preview application,
- change the gtk-print-preview-command setting in your gtkrc file, e.g.
- gtk-print-preview-command = "ggv %f"

* GtkMenuShell is now defined as an abstract type. It was already
documented as an abstract class, and there is little reason to
instantiate it.
+
+* The GtkTooltips struct (this is the old tooltips API) is now considered
+ private. Code that used to access this struct, in particular the
+ tips_data_list field, will need to change. All of the old tooltips
+ API has been deprecated in favour of a new implementation and
+ API. This affects all of the gtk_tooltips_ functions, and functions
+ which take a GtkTooltips argument, such as gtk_tool_item_set_tooltip()
+ and gtk_menu_tool_button_set_arrow_tooltip().
* The memory management of the GtkRecentManager object has been changed,
as using the screen didn't guarantee that the singleton instance was
the gtk_recent_manager_get_default() function is guaranteed to be valid
for the entire lifetime of an application.
+* A number of interfaces that have been superseded by newer interfaces for
+ a long time have finally been deprecated. This includes
+ gtk_widget_ref/unref(), gtk_rc_style_ref/unref() and the old file selector.
+
+* The various coordinate systems in use in GtkTreeView widgets have
+ been clarified in the documentation, and in the cause of doing so,
+ the functions gtk_tree_view_widget_to_tree_coords() and
+ gtk_tree_view_tree_to_widget_coords() have been deprecated in
+ favour of a new family of gtk_tree_view_convert_ functions.
+
+* gtk_menu_item_remove_submenu() has been deprecated in favour of
+ gtk_menu_item_set_submenu (..., NULL).
+
+* gtk_default_draw_check() has been fixed to really decrease the
+ indicator size by one pixel to ensure an odd size instead of
+ accidentially increasing it.
+ Consequently, gtk_cell_renderer_toggle_render() could be fixed to
+ not subtract 1 from the size passed to gtk_paint_option(), which
+ was just a workaround for above off-by-two for even sizes (theme
+ engines now get the real indicator size passed).
+ The default toggle size of GtkCheckMenuItem and GtkCellRendererToggle
+ has been changed to 13 to be consistent with GtkCheckButton.
+ The only visible change with default settings is that the indicator in
+ GtkCellRendererToggle has changed its size from 11 to 13 and is now
+ consistent with menus and toggle buttons.
+
+* GTK+ has always required that gtk_init() (or a variant thereof) is
+ called before any other GTK+ function. Some applications call functions
+ like gtk_clipboard_get() to check if they need to call gtk_init(),
+ anyway. A change in GLib 2.14 has recently broken this unsupported
+ practise. It is worth pointing out that calling gtk_init() twice
+ does no harm.

======================
GTK_OBJECT_IS_FLOATING() will still work, but direct checking
of the GTK_FLOATING flag will no longer detect the floating
reference. Details about floating references can be found in the docs:
