GtkInfoBar

 - A new widget to show a transient 'message area' inside a content
   pane. The API is similar to GtkDialog and supports theming for
   different message types (warnings, errors, etc)

Changes in GtkBuilder

 - Scale marks can be specified in builder markup

 - GtkAssistant action widgets can be added in builder markup

Changes in GtkLabel

 - GtkLabel can show embedded URLs, much like SexyUrlLabel

Changes in GtkEntry

 - GtkEntry has been refactored to follow the model-view pattern,
   with GtkEntryBuffer as model. One intended use case for this is
   to support 'secure memory' for password entries

Changes in the file chooser

 - Backup files are hidden by default

 - GTK+ remembers the sorting state of the file list

 - File sizes are shown by default

 - The 'Create Folder' button can be disabled with the the
   ::create-folders property

Changes in printing support

 - GTK+ supports authentication against CUPS servers

 - A backend for the PAPI printing system has been added

 - The file and lpr backends can print multiple pages per sheet

 - The file backend can produce svg files

 - GTK+ supports printing an application-defined 'selection' in
   addition to the usual page ranges

 - The print dialog can optinally include the page setup controls,
   avoiding the need for a separate page setup dialog in many
   situations

Changes in theming support

 - The bullet character used in invisible entries can
   be set by themes with the ::invisible-char style property

 - The file chooser can show different icons for xdg user dirs.
   The icon names are folder-documents, folder-download, folder-music,
   folder-pictures, folder-publicshare, folder-templates and
   folder-video

 - The GtkInfoBar uses symbolic colors for theming its background color
   depending on the message type. The color names are info_fg_color,
   info_bg_color, warning_fg_color", warning_bg_color, etc.

GDK changes

 - GDK has been rewritten to use 'client-side windows'. This means
   that GDK maintains its own window hierarchy and only uses X windows
   where it is necessary or explicitly requested. Some of the benefits
   of this change are
   * Reduced flicker
   * The ability to do transformed and animated rendering of widgets
   * Easier embedding of GTK+ widgets, e.g. into Clutter scene graphs
   See gdk-demo for some simple examples of client-side windows in
   action. See
[url]http://library.gnome.org/devel/gtk/2.18/gtk-migrating-ClientSideWindows.html[/url]
   for information about possible problems when moving to
   client-side windows.

* GArray, GPtrArray, GByteArray, GTree and GMappedFile can be reference
  counted.

* The GLib mainloop supports per-thread default contexts.

* GIO now provides types and methods for IP addresses and UNIX domain
  socket addresses.

* GResolver provides asynchronous and cancellable APIs for resolving
  hostnames, reverse lookup of IP addresses and resolving SRV records.

* Support for network IO has been added to GIO, including low-level
  socket API and high-level API for network connections and services.

* GIOStream and its subclasses have gained support for read-write
access.

* GIO supports starting and stopping of drives, which can be used
  in connection with external hard disk enclosures, disk arrays, iSCSI
  devices, etc.
