Users can now password protect sections of documents directly from mobile devices (a feature that used to require a Windows PC). Those with an iPhone 5s or newer will also find that they can now unlock password-protected sections of documents using Touch ID. That feature isn’t mentioned in the iPad change log, so users on the iPad Air 2 or iPad mini 3 might need to wait for a future update to enable it.
iCloud Drive support is now present as well, allowing users to access files stored in Apple’s storage solution or in other third-party apps that have registered as document servers. Other additions, such as the ability to rearrange pages in the iPhone version or open notebooks stored on a self-hosted SharePoint Server round out the update’s feature set.
