How do I check which mobile build I'm on?

[KwisatzHaderach]

Sorry, this is a really basic question. I have been part of the insider slow ring until recently. Yet it happens that just tonight my 930 updated to a new build. I wasn't aware of an official update, so I wanted to check the version number Iam now on, but alas! I can't seem to find it. It is not under the--> extras-->info option... Can't find any hints on the web either. So, can anyone show me directions please?

Much appreciated!

Or you can use freeware update checker or also when you connect your device to windows device recovery tool... it shows which OS version you have and which is available officially
