In iOS 8 you can now use Touch ID to view your passwords. The password menu has also been moved so it takes less clicks to get to it. Also finally we can now choose which account to use when you have more than 1 account per website. This sort of worked with iOS 7 but it disappeared along the way but is now back, presumably much better as well and similar to how OS X handles it. Of course this is all specific to iOS devices.
No news yet on keychain access changes on Macs unfortunately. I would love for secure notes to Sync to iOS devices, that be sweet.
