I have Xara Web Designer Premium 17 and Xara Designer Pro X 16. Both of them are now incapable of updating as they haven't been renewed. I really would like to add the webp format for my images as I have many and the space saving should be great. I have options to update both versions when I open them up but do they both have webp as part of the update, and which version is superior to the other anyway as I only want to update one of them.
