iDB has a video rundown of changes in the most recent beta of iOS 11. This is the 5th release and there have been as many iterations of changes. Two things that caught my attention is the iCloud for Messages features have been removed for a future update, perhaps after launch.
The other tidbit is the Facetime ringtone has changed. The new tone is more subdued lower frequency tone that isn't as piercing.
