Mac OS X High Sierra: Blender 2.79

Version 2.79 (2.79 2017-09-11, Blender Foundation)

This has been driving me crazy.

I want to install the latest version of:

https://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Add_Mesh/Add_Extra

When I look in my blender prefs/addons, I see:


Why does that say version 0.3.2?

The WIKI page says it should be version 0.5.

How do I know if I am running the latest version of the addon?

Thanks!
