+    Thanks to Adriano Rafael Gomes <adrianorg@arg.eti.br> (Closes: #816949)
+  * Fix spelling error in debian/copyright: exeption -> exception.
+    The spelling error is in the quote from the original mail to the
+    upstream author, so it is borderline to be fixed to silence lintian.
+  * Fix spelling error in NEWS.Debian
+  * Update copyright years for debian/* packaging files
+  * Drop unnecessary lintian-overrides
