Upgrade OH2 beta3 --> beta4 issues

How can I find out which beta/version is actally installed?

Identify OH2 Version?

Apologies is this is easy. But how can you confirm what version you are running? If it is the latest snapshot build or other? Is this identifiable anywhere with the PaperUI or elsewhere? Or only by stopping and starting OH2 manually to see the version? Was also wondering when your apt-get upgrade. Is there any check to verify if you are potentially upgrading a stable release over a newer snapshot release?
