This is the last beta release of what will become GTK+ 3.0.
The amount of changes that went into this release was larger
than anticipated, and we will therefore give it at least a
week of little to no changes before declaring 3.0 done.

Notes:

 * GTK+ 3 will be parallel installable with GTK+ 2.x, and
   this release has been prepared to test this by renaming
   all .pc files, libraries, include paths, and so forth,
   to include a '3.0' component.

   An exception to this is the gtk-update-icon-cache utility,
   for which parallel installation would make little sense.
   Distributors can choose to build GTK+ 3 with the
   --enable-gtk2-dependency configure option to avoid building
   gtk-update-icon-cache, and rely on the GTK+ 2.x version of
   the utility instead.

 * GTK+ 3 removes deprecated API from the GTK+ 2.x series and makes
   struct members unavailable that have been GSEALed in 2.x. Therefore,
   applications can be prepared for porting to GTK+ 3 by making sure
   that they build with -DGTK_DISABLE_DEPRECATED and -DGSEAL_ENABLE.
   For more information about porting concerns, see the porting guide
   that is included in the API doc:

   http://library.gnome.org/devel/gtk/2.99/gtk-migrating-2-to-3.html

   The removal of GSEALed struct members and deprecated APIs has been
   completed. Any deprecated APIs in this release will not be removed
   before GTK+ 4.0.

 * Bugs should be reported to http://bugzilla.gnome.org.


What is GTK+
============

GTK+ is a multi-platform toolkit for creating graphical user
interfaces. Offering a complete set of widgets, GTK+ is suitable for
projects ranging from small one-off tools to complete application
suites.

GTK+ has been designed from the ground up to support a range of
languages, not only C/C++. Using GTK+ from languages such as Perl and
Python (especially in combination with the Glade GUI builder) provides
an effective method of rapid application development.

GTK+ is free software and part of the GNU Project. However, the
licensing terms for GTK+, the GNU LGPL, allow it to be used by all
developers, including those developing proprietary software, without
any license fees or royalties.

Overview of Changes in GTK+ 2.99.3
==================================

* This release adds some forgotten padding to class structs,
  and thus breaks ABI for a last time before 3.0

* Many Introspection annotation improvements

* We no longer build the gtk-update-icon-cache utility, and
  use a preexisting one, if --enable-gtk2-dependency is passed
  to configure

* GtkBuilder can now fill GtkComboBoxText and GtkMenToolButton
  widgets with data, as well as GtkFileFilters and GtkTextTagTables

* GtkImage now has a ::use-fallback property to allow generic
  fallback with GIcons and icon-names (e.g. for symbolic icons)

* There's a new gtk_text_view_get_cursor_locations() to enable
  popup-at-cursor functionality

* The application chooser widgets can now set a custom
  dialog heading

* The file chooser and application chooser widgets have received
  minor visual improvements

* gtk-auto-mnemonics is now backed by an XSetting

* Defaults for GtkSettings, as well as theme-specific settings,
  are now read from key files

* Key themes are now supported again, their syntax has been changed
  to be CSS-like

* More objects use GtkStyleContext directly now:
  GtkTreeView
  GtkIconView
  GtkCellArea
  GtkCellRendererText
  GtkCellRendererPixbuf
  GtkCellRendererAccel
  GtkCellRendererProgress

* GtkPlug and GtkSocket have been reduced to X11-specific API, and
  using them requires including the <gtk/gtkx.h> header, and uses
  of GdkNativeWindow in their APIs have been replaced by the X11
  Window type.
  A number of other API changes were necessary in GDK to ensure
  that multiple GDK backends can coexist:
  - GdkNativeWindow has been dropped
  - The GdkEventOwnerChange owner field is a GdkWindow now
  - The GdkEventSelection requestor field is a GdkWindow now
  - The GtkWidget::client_event vfunc is gone
  - GdkEventClient is gone, together with related API:
    gdk_add_client_message_filter
    gdk_display_add_client_message_filter
    gdk_screen_broadcast_client_message
    gdk_event_send_client_message
    gdk_event_send_client_message_for_display
    gdk_event_send_clientmessage_toall
  - gdk_drag_get_protocol_for_display has been changed to
    gdk_window_get_drag_protocol

* Migration guide and tutorial and other documentation improvements
