JudasIscariot: Would you like a cigarette and a lie-down? :P
As for putting this news on the front page, I am not sure calling attention to the fact that we were missing the Level Editor for some time is a good idea but that's just my take on things :)
Speaking for myself, the lack of a level editor was what kept me from buying Hotline Miami 2 for the longest time until it was heavily discounted, after I'd read lots of complaints about the levels and bugs and while already in the possession of HM1. A decent level editor that's not reliant on Steamworks could give us lots of good levels in the long term, though, and sets the game apart from its predecessor. That's also why I think an announcement would be worth it as there might be others with similar feelings and it could draw the attention of any modders who were also interested in the level editor.
On a related note, it would be more convenient if GOG would have a public changelog tab for games so that there would be no need for announcements of updates, though I imagine this is probably a lot more complicated to implement than it looks from a user's perspective.
