   * New upstream release.
   * Upgraded to policy 3.7.2 (no changes required).
+  * Introduced a new binary package: libxmpp4r-ruby-doc, to match
+    other packages from the pkg-ruby-extras team.
+  * A hack was needed because the distclean target of setup.rb wasn't
+    working when a 'data' dir was used.
