The repo being archived happened after that UPDATE post that you mention. So the project has gone from suspended, to un-suspended, and now it's suspended again (and the repo got archived this time).
Edit: I see I'm being downvoted for just providing facts, so here's some evidence: you can see on the main project page that the repo was archived on 11 Sep[0]. Looking in the commits, the "UPDATE" message was commited on 6 Sep[1].
