Here are some key changes in recent updates:
Google Play Services is the "engine" behind your apps. Without it, you can't log into your Google Account, use Maps, or even download new apps from the Play Store. Since updates are no longer pushed automatically to KitKat, you must manually sideload the final compatible version to maintain as much functionality as possible. The Final Compatible Version
The correct is version 21.33.56 (or the final 21.39.xx variants). Specifically, you need the variant ending in -034 or -036 for 240 DPI devices, or -030 for 320 DPI.
