+dh-buildinfo (0.11+nmu2) unstable; urgency=medium
+
+  * Non-maintainer upload.
+  * Replace call to Dh_Lib::buildarch() with Dh_Lib::hostarch() to
+    avoid a deprecation warning.  Thanks to Clint Adams for the
+    patch.  (Closes: #882334)
+  * Replace manual uses of install(1) with debhelper's install_dir
+    and install_file.  They are faster and support "Rules-Requires-Root"
+    out of the box.  Thanks to Clint Adams for the patch.
+    (Closes: #881421)
+  * Add the (now) mandatory "build-arch" and "build-indep" targets
+    (plus add "install-arch" and "install-indep" for consistency).
+  * Set "Rules-Requires-Root: no" as dh-buildinfo does not require
+    (fake)root to build (after the above changes).
