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+ 2.20.x to 2.90.0

* GtkExtendedLayout: Width-for-height geometry management.
  This change is known to currently cause minor problems in
  some applications, see
  617444 GNU emacs warnings with extended layout GTK+
  617556 inkscape toolbars broken with extended layout

* gtk_icon_theme_load_symbolic: Support for 'symbolic' icons

* Applications can indicate their preference for a dark theme
  variant by setting GtkSettings::gtk-application-prefer-dark-theme

* GtkTreeModelFilter can be more usefully subclassed

* Tooltip positioning has been changed to make it less likely
  that the tooltip covers up the widget that it relates to

* Deprecated functions have been removed (though some more work
  remains to be done in GDK)

* This release is parallel installable with GTK+ <= 2.22, by renaming
  .pc files, libraries, include paths, module paths, gtkrc files, etc
  to include a '3.0' in its name.

* Updated translations:
