Floating Social update

I want Floating Social to appear on the home page. I see here:

In the latest release (v1.2.2, just released), the plugin comes with a "Show on front page" option, accessible in sitewide plugin settings ("Settings" > "Floating Social").

but the WPMU version is labeled 1.5.2 and does not have this feature.

I thought you keep the plug-ins fully up to date. I must be missing something...

Thanks for clarifying.
