+ 
+   * New upstream release.

+   * d/control:
+     - Use debhelper compatibility level v13.
+     - Remove Dean Evans from uploaders because of long inactivity.
+       Thank you for your contribution as the initial maintainer!
+     - Bump Standards-Version to 4.5.1. No changes needed.
+     - Add libqt5svg5 to Depends, required for SVG images (Closes: #975314).
+     - Depend on qml-module-qtqml just to avoid issues with Qt 5.14 and earlier
+       (Closes: #973855).
+   * d/copyright:
+     - Update years.
+     - Change Upstream-Contact from the recently closed mailing list to
