In case you haven’t heard, the Sixth Edition of the Project Management Body of Knowledge (PMBOK) is due to be released on September 6, 2017.
PMBOK Sixth Edition will have Agile in every Knowledge area and a 190-page Agile Practice Guide will also be available for $49 (but free if you order a PMBOK.) Not clear if the Practice Guide is also free for PMI members who already get a PMBOK gratis.)
As to the new PMP exam itself, it’s typically issued six months after the book. So, no date announced but expect it by March 31st or so.
