+ gtk+3.0 (3.22.8-1) unstable; urgency=medium
+ 
+   * New upstream release.
+   * Stop patching gtk-doc.make and instead run gtkdocize via the upstream
+     provided autogen.sh on autoreconf. The gtk-doc-tools version in Debian has
+     been fixed to properly handle the installation of HTML images for
+     out-of-tree builds.

+ 
+   * Team upload
+   * d/p/gdk-x11-Check-if-we-have-access-to-GL-before-using-G.patch:

+     available (Closes: #847366)
+   * Override Lintian error source-is-missing for
+     debian/missing-sources/zlib.js-0.1.6/deps.js. It is a generated
+     file, but the script to generate it is also present.
