Apple has updated Keynote, Pages and Numbers on both iOS and macOS. The main improvement in all programs is easier editing.
For example, on iOS you can always open your files in edit mode, and there are on-screen keyboards to make settings and enter data easier and more precisely.
On macOS, you can enjoy an improved media browser. Here the search function has become a bit more precise and there are new categories. In Keynote, there is a practical function for holding presentations: it is now possible to display your own notes for the current slide as well as the upcoming slide in parallel.
