Wiki feature in Discourse

While looking in the latest Discourse commits I saw a “wiki topic” commit in the master branch. It seems a new kind of post are coming :

Associated discussion on meta.discourse:

Oudeyer test: This is a post editable by others (everyone ?)

I upgraded the forum. This topic has now the wiki feature, meaning anyone (?) can edit it.

I could edit the first post in the topic, but not your latest post. Maybe something in the setting should be changed ?

I think the idea with the wiki feature is to allow the first post to be the actual wiki post and the replies a way to discuss the content.

Now, the big pen icon is clickable and permits to edit the wiki post.
