You were downvoted but right. The changelog[0] shows that the current minor version (4.6) came out in 2020, and its only had 3 bugfix releases since then, most recently in 2023. A lot has changed since 2020, so this doesn't know about the major iCloud updates, or Apple Intelligence, or UI changes (not just talking about Liquid Glass either).

None of those things imply that it's broken or unusable. Still, it means it's going to feel like a dated app and that's not fun.
