Am I reading an announcement post about a feature that is going to happen in future?
Yes, you are. As it is said in the post, this is the thing we are working on and it will be available in a couple of days. The community has repeatedly been asking for announcements of all new things in advance and we are listening to what the majority of our users want. There will be no updates or changes what so ever before they are publicly announced and introduced to the public a couple of days before they happen.
