See fix, improvement and new feature easily

Hi everyone !
I just discovered this Monday Docs feature and it also seems that sub items get improved recently but not sure of that.
Anyway, with all of this, i was thinking it would be cool to have like a patch note or just a dedicated page to all this modification. Or maybe if it already exists please tell me where to find it.
I know some feature are announced in the community but it is not very clear.
Thank you !
