After a long wait, the Nougat update appeared on my phone earlier today, It had been available for Vodafone user's since late January but now appears to be fully rolled out for everyone in Germany. The size of the update is 1232.44 MB.

If you do not have the update yet, you can check if it is available for you by going to: 

Settings -> About Device -> Download Updates Manually.

Android Nougat is the latest version of Android (v. 7) and brings in some important features, I will post some noticeable changes in the Galaxy S7 edge after installation is completed.
