Today, Apple has released updates across different platforms, including iOS, watchOS, OS X, as well as for the Apple iTunes software. While it was iOS 9.1 being sent to the Apple iPhones, the Mac systems are receiving the new OS X El Capitan 10.11.1 update. iTunes is receiving the 12.3.1 update, but that has to do only with stability and performance, while the OS X updates has quite a big change log.
For the Apple Macbook 2012 version, the size of the OS X El Capital 10.11.1 update is as big as 942MB. Here is the change log, if you want to know what has changed.

You will get this update only if you are already running the OS X El Capitan 10.11 update that was recently made public. If you are, then go to App Store and check for updates section, and you will notice the update for not just this, but also for iTunes.
The addition of emoji characters is surely a great one, but it is noticeable that Apple has worked to make the compatibility of the Office 2016 better.
You may want to even update Apple iTunes to the latest version, i.e. 12.3.1 that works only with OS X 10.11.1, and it is a necessary one since it brings some improvement to performance and stability of the software.
Update these from Apple App store, and make sure you take a backup of important data before proceeding with the update, although in most cases, no changes occur to the stored files during an update process.
