Buffer Offset function

Hi everybody,

I’ve read on the 6.07 version’s release notes that a new offset function for the buffer~ object has been added.

"buffer~: new ‘offset’ function to add a constant" (from the release notes)

I’m wondering how to access that function, I’ve tried to check in the help and reference but there is no mention of this feature.
I also tried to send a message prefixing "offset", as you would normally do with other functions, but no results.

Anyone managed to dig into this?
Thanks!
