NZBGET Upgrade

I am currently running NZBGET ver 14.1 , yes, way behind. What is the best way to upgrade it?
I have been to the NZBGET site and they say to just download the latest version and install it, this apparently will keep all settings and just update it.

Seems like a .bin file would be easier and just install it via the WD App section.

Or should I just leave well enough alone and stay on ver 14
Any info appreciated

Can I just download the 2.09 bin file from the 3rd party apps here on the WD site and use the apps section in the WD interface and install it this way?..anyone?
Would I need to uninstall my current version?
