You can continue running iPhoto after upgrading to 10.10.3. Now it is to sync with your iPhone, iPad, and even other Macs with iCloud Photo Library enabled.
The iOS 8.3 update adds support for wireless CarPlay. Basically Apple's in car solution CarPlay syncs with your current iPhone and simply put the most needed information such as messages, maps, music and Siri on your dash. Now with the iOS 8.3 update CarPlay will now work even when the iPhone is still in your pocket.
