Advice on non-updated syllabus related to updated publishings

Friends, I am going to take F2 and F3 in June, so I checked previous syllabus with the new one, and both in F2 and F3 it is written that there are not changes (deletion or addition) just one simple explanation included in one sub-sub-category of F2 topic (I know most of you are already aware of this).. The issue concerns me mostly is, if there is no change in syllabus why there are updated publishing exist ???
Personally, I rely on BPP publishing (because of platinum accreditation), unfortunately I don’t have chance to look through different editions of BPP (F2 and F3). If some one has reasonable explanation I will appreciate that answer 🙂 I know I am novice in ACCA qualification but I am sorry for this kind of question, I need help from experienced users of opentuition on this topic.

thnaks in advance
