- Removed "Result must outlive all its Row children" section of the C   API limits chapter in the userman, now that the limit is lifted - That left just one topic in that chapter, so moved it to a new   second-level section at the end of the tutorial chapter, "Concurrent   Queries on a Connection".  (Executive summary: don't do it.) - Added a new chapter on using MySQL++ in multithreaded programs, in the   same chapter position as the old C API limits chapter.  The rewritten   material that covers the concurrent query limit refers to this new   chapter, since it also touches on threads.
