Change in syllabus for sep 2018 exams

Dear Sir, First of all, I would love to thank you for the efforts you have put in for providing lectures and notes. Its really great to find such a useful platform. I had just one question, I am planning to appear for Sep 2018 exams for 2 papers out of P2, P4, P7 and upcoming 4 hour exam in replacement of P1 & P3. I have'nt taken a decision on that yet. But all the materials and lectures state that these are applicable till June 2018 exams. Can I refer them for Sep 2018 exams as well? Or should I wait for new materials? In the latter case, by when can we expect the updated materials to be uploaded? Thanks in advance.
