This is a development release leading toward 3.0.

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.

* 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
-DGTK_DISABLE_DEPRECATED
  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 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 from GTK+ 2.90.7 to 2.91.0
==============================================

* The rendering cleanup work has landed. This is a large change that
affects many APIs.
- All GtkStyle functions have been changed to take a cairo_t argument
instead of a window + area.
- GdkPixmap is gone. APIs that took pixmaps are being replaced by ones
that take pixbufs or cairo surfaces, or regions (where pixmaps were
used as masks). In background handling, pixmaps have been replaced
by cairo patterns, see gdk_window_set_background_pattern().
- GdkColormap is gone. It is replaced by visuals, see
gtk_widget_set_visual().
- The ::expose-event signal on GtkWidget has been replaced by a
::draw signal.
- gtk_widget_get_snapshot() has been removed. Instead,
gtk_widget_draw() can render a widget onto an cairo_t.

* The GtkSizeRequest interface has been merged into GtkWidget, and
GtkCellSizeRequest has been merged into GtkCellRenderer. The wrapper
functions have been renamed to include 'preferred', e.g
gtk_size_request_get_width() is now gtk_widget_get_preferred_width()
and gtk_cell_size_request_get_width_for_height() is now
gtk_cell_renderer_get_preferred_width_for_height().

* GtkObject has been removed. The ::destroy signal has been moved
to GtkWidget. At the same time, GtkWidgetFlags have been removed,
they already had getters and setters anyway.

* GtkWidget has gained generic alignment and padding properties:
halign, valign, margin-left, margin-right, margin-top, margin-bottom
These can be used instead of container-specific child properties or
GtkMisc and GtkAlignment widgets.

* Container widgets can now let GTK+ handle border-width for them, using
gtk_container_class_handle_border_width()

* The GtkEditableClass struct has been renamed to GtkEditableInterface

* Mouse wheel scrolling has been removed from GtkNotebook

* The default policy for scrolled windows has been changed to
'automatic'

* Global url hooks have been removed from GtkAboutDialog and
GtkLinkButton

* The global window creation hook has been removed from GtkNotebook

* The error handling in GDK has been modernized and avoids synchronizing
X requests as much as possible

* Fixed Bugs:
