Dear you are right that this is the latest update of Android 4.4.4. The main reason behind this update is that recently after the launch of Kitkat, a security virus named "Heartbleed" bug Google managed to remove that issue with this update.
Along with the security issue, many more improvements are also done in Android. The UI improvement is given for more better interface, Also the issue of fast battery draining while using the camera is also resolved with this update. But unfortunately, this update is only offered in Nexus series. No other product is having this update currently.
