Change in syllabus to F8 and F9 for the September 2026 exams

Are there any changes to the syllabus for F8 & F9 papers for sepetmber? I have the BPP revision kits valid for the June 2026 exams for both F8 and F9. Since the new editions are available for the September 2026 exam, do I need to get the new revision kits or can I rely on the ones I have? Would there be any changes in the syllabus? I am planning to write my exams in Sep 2026. Same Q regarding the OT lecture notes, they are only valid till the June exams, can I use them for the Sep sessions ? Thank you.
