Safari user agent on Mac OS Big sur RC2

Hello,
Safari user Agent is showing as Mozilla/5.0 (Macintosh; Intel Mac OS X 10156) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.0.1 Safari/605.1.15
Instead of OS 11 it is reporting as 10.15

On older betas it was getting reported as Macintosh; Intel Mac OS X 11_0.

Is this bug or intentional?
.

I wish they would announce it in release notes.

From https://bugs.webkit.org/show_bug.cgi?id=216593 :

The world apparently isn't ready for macOS 11.0 in User Agents. Because of the depressing UA sniffing code on the web, let's just report our current shipping release until things settle down.
