You can see for yourself by looking at the syllabus on the ACCA website – they list the additions and deletions at the end.
However, the deletions (Basic DCF calculations) are actually still examinable. It is just that they are assumed knowledge from Paper F2 and so are no longer listed in the F9 syllabus.
The additions are the treasury function, discussion of systematic and unsystematic risk, and the relationship between portfolio theory and CAPM (all of which are covered in the OpenTuition course notes).
