[Question] What does the hollow badge on the tab mean?

[bergamin]

This seems to be a new feature, but I couldn't find it mentioned in the release notes. Some have the badge be solid and some are a torus. It doesn't seem to be an option in the menu either:

So, what does it mean?

Thanks

Filled circle means that the repository contains uncommitted changes.

I see. Yeah, that's definitely better than the *.

Thanks!
