   * ITIL manual:
     - Norwegian Bokmål: Allan Nordhøy.
 
+  [ Wolfgang Schweer ]
+  * documentation/common/Makefile.common:
+    - Set timestamps for PDF and EPUB manuals to the start of Unix time. Also,
+      in case of EPUB files the generated article ID is unique and needs to be
+      tweaked and (beeing a zip file) strip-nondeterminism is used to get rid of
+      the remaining difference.
+      With these changes the manuals can be built reproducibly.
+  * debian/control:
+    - Add strip-nondeterminism to Build-Depends-Indep.
