+Gtk# 2.99.2 - 2013-12-03
+===============================================================================
+
+Gtk# 2.99.2 is the third beta release of C# bindings for GTK 3.x.
+
+This version of Gtk# provides bindings for the API exposed by these libraries:
+  * cairo 1.10.0
+  * glib 2.28.0
+  * pango 1.28.3
+  * atk 1.32.0
+  * gdk-pixbuf 2.22.1
+  * gtk+ 3.0.0
+
+There is no API stability guarantee for now, but we will try to keep breaking
+changes to a minimum.
+
+This version of Gtk# can be installed in parallel with Gtk# 2.x, and should not
+have any impact on applications using Gtk# 2.x.
+
