Post title marquee scroll version 8.4

Hello,
I use your plugin for my site, version 8.3.

I received notification to the update to version 8.4, but there is no information about this version on the page of the plugin.
The last update date is 2014-08-25 and the changelog is to version 8.3.

Can I update?

Thank you, very useful plugin.
Bye, Pier
