Installing iOS 9 will change your iPad keyboard from all uppercase letters to all lowercase letters. The change is from Apple adding a San Francisco system font to iOS devices. You can switch back to an uppercase format by opening the Settings app on your device and navigating to General > Accessibility > Keyboard. From here just tap the "Show Lowercase Keys" slider so it is in the OFF / WHITE position. Now your iPad keyboard will look like it did before you switched to iOS 9.0.
