How do I check what version of Platform I am currently running?

There are a few methods to do this.

Method 1

Right-click on the Listener and click 'About'.  If the Listener was not updated in quite some time, it may be inaccurate.

Method 2

Log into Platform and scroll down until you see the version at the bottom of the screen.

Method 3

When logged into Platform, navigate to settings and then Nodes.
