Tabs uncontrolled mode not ready?

[ivnnv]

Hi, Ive updated to the latest version (5.7.0) and it seems the uncontrolled version for Tabs is not fully ready?

CTabs have activeItemKey and CTab has itemKey but CTab@5.7.0 doesnt have itemKey prop (it has in main tho)
So the comment for CTabs.onChange (In uncontrolled mode, this callback is called after internal state updates) still dont apply at least until a new version/patch is released? or Im missing something?
In the documentation the examples shown use activeKey and they work fine.
