+Docbook processing
+------------------
+
+xmlto with fop backend
+
+ - Overlap footnote and text body in some cases (BTS #683197)
+
+ - incorrect index (missing page numbers for some, create wrong page
+ number for some).
+
+ - missing images (possibly BTS #567122)
+
+xmlto with default backend
+
+ - fail to process the docbook source (possibly BTW #683163)
+
+dblatex
+
+ - do not end a <part> when it should, gluing following chapters as if
+ they belonged to the last <part> (BTS #683166).
