This is a development release leading toward 3.0.


 * 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.

 * GTK+ 3 will remove deprecated API from the GTK+ 2.x series
   and make 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
   and -DGSEAL_ENABLE. For more information about porting concerns,
   see the porting guide that is included in the API docs.

 * Bugs should be reported to

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

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 from GTK+ 2.91.6 to 2.91.7

* The treeview-refactor branch has been merged, bringing more
  flexible cell arrangement with GtkCellArea, GtkCellAreaBox, etc

* The gdk-backend branch has been merged. This branch cleans up the
  internal frontend/backend separation in GDK, with the ultimate goal
  of allowing to build a single gdk library that contains multiple
  backends (interesting combinations are x11+wayland or quartz+x11).

  For now, GDK is still restricted to a single backend, but
  as a first step, the libraries no longer include the backend name
  in their soname, but are just and

  Only the x11 backend has been kept up to date with this cleanup
  work, other backends are broken in this release.

* Deprecations and removals:
 - G_SEALed struct members have been removed from GtkWindowGroup,
   GtkDrawingArea, GtkTreeStore, GtkTreeModelSort, GtkTreeSelection,
   GtkSocket, GtkPrintJob, GtkSelectionData
 - Input device handling:
   - gdk_display_list_devices, gdk_display_get_core_pointer,
     gdk_input_set_extension_events, gtk_widget_set_extension_events,
     gdk_devices_list have been removed
   - gdk_display_warp_device has been replaced by gdk_device_warp
   - gdk_enable_multidevice has been replaced by gdk_disable_multidevice
 - Drag-and-Drop:
   gdk_drag_context_new, gdk_drag_find_window and gdk_drag_get_protocol
   have been removed
 - Property handling:
   Functions that deal with X11-specific encodings such as Compound Text
   have been moved to backend-specific API:
   gdk_utf8_to_compound_text[_for_display], gdk_free_compound_text,
   gdk_text_property_to_text_list[_for_display], gdk_free_text_list,
 - Foreign windows:
   Functions for dealing with GdkWindow wrappers around foreign
   windows have been moved to backend-specific API.
 - Application launching:
   The gdk_spawn_* APIs have been removed, since they were trivial
   wrappers around g_spawn_* on most platforms and can be replaced
   by GIO GAppInfo APIs.
 - Misc. other functions: gdk_net_wm_supports, gdk_set_locale,
   gdkx_visual_get have been either removed, gdk_set_sm_client_id
   has been moved to backend-specific API.

* A number of GTK+ widgets have been ported to use GtkStyleContext
  directly for rendering

* The tracker search backend for the file chooser has been updated
  to work with libtracker-sparql as available in tracker >= 0.9

* The GtkAboutDialog has been given a facelift. It no longer
  opens second-level dialogs

* The GDK X11 backend now uses XI2 (including multi-device capabilities)
  by default. Use gdk_disable_multidevice() to switch back to the
  XI1/Core implementation
