+ The new query handling module of b10-auth did not handle type DS
+ query correctly: It didn't look for it in the parent zone, and
+ it incorrectly returned a DS from the child zone if it
+ happened to exist there. Both were corrected, and it now also
+ handles the case of having authority for the child and a grand
+ ancestor.
