Release schedule
I consider release schedule being part of the documentation, but I can understand if you'll disagree.
There is currently no release schedule for the 47.x. It's kinda late now, these things used to be done shortly after the first previous release (in this case after the 46.0 release). Release schedule is responsibility of the release team, from my point of view.
There will be no https://wiki.gnome.org/FortySeven too. Where does that will reside now, please?
