+# Version 1.2 (8/30/2010) (CMake 2.8.3)
+#   * Merge patch for detecting gdk-pixbuf library (split off
+#     from core GTK in 2.21).  Thanks to Vincent Untz for the patch
+#     and Ricardo Cruz for the heads up.
+# Version 1.1 (8/19/2010) (CMake 2.8.3)
+#   * Add support for detecting GTK2 under macports (thanks to Gary Kramlich)
+# Version 1.0 (8/12/2010) (CMake 2.8.3)
+#   * Add support for detecting new pangommconfig.h header file
+#     (Thanks to Sune Vuorela & the Debian Project for the patch)
+#   * Add support for detecting fontconfig.h header
+#   * Call find_package(Freetype) since it's required
+#   * Add support for allowing users to add additional library directories
+#     via the GTK2_ADDITIONAL_SUFFIXES variable (kind of a future-kludge in
+#     case the GTK developers change versions on any of the directories in the
+#     future).
 # Version 0.8 (1/4/2010)
 #   * Get module working under MacOSX fink by adding /sw/include, /sw/lib
 #     to PATHS and the gobject library
