Updating BP-Daily

Hi there,
Quick question. My site (www.gbiportal.net) is telling me that I have BP-Daily 3.9.9.2 installed, and it is not telling me that there is an update. I tried updating just now, but it tells me there is no update.
But, I'm seeing in the BP-Daily listing on WPMUDEV that there is a version 4.1.7 now.
What's the best way to proceed?
And I don't have to update anything in the child, right?

Thanks for your help,
Laurie
