• All of your configured servers now stay synced for offline browsing in the background, not just the one you're currently viewing, so switching servers shows your documents right away
• An offline download that is interrupted, by losing connection or by the app being backgrounded, is now retried instead of leaving a list stuck partway while reporting it as fully downloaded
• Background sync and an open document list downloading at the same time no longer leave gaps in a cached list
• A document you no longer have permission to view is no longer served from the offline cache as though the server were unreachable
• A failed cleanup of documents deleted on the server no longer stops the rest of the offline refresh
• Switching to another server no longer throws away the offline download already running for the one you left; it keeps going in the background instead of starting over next time you switch back
• Data used by the background library download is now counted under its own category in the Offline & Sync transfer statistics, instead of being lumped into "Other"
• Switching a server to "Entire library" now starts downloading document notes and file metadata straight away, instead of waiting until the next time you reopen the app
