Key differences between iPadOS 17.7.2 and 18.2.1 on iPad Pro

Hi! So, I have the last of the iPad Pro models with the Lightning connector (model A1701) and it can’t be updated to iPadOS 18, so the latest version it supports and is running is 17.7.2. Other than the Apple Intelligence features that were advertised prominently during the transition period, what are the major differences between 17.7.2 and 18.2.1?
