Oh hey I remember that now. I posted the list in a server and explained what each one did, then forgot about it.
For clarification:
v9 events work like sentences. You have the object doing the action, an action, what it acts on, and things describing the action.
fakekillbrick doesn't make the brick just appear to be killed, it does a mini-games style kill on it. So when it is killed, you can fall through it, shoot through it, etc.
The targets section is incomplete. You can also effect the client, player, and another brick.
Printoverflow/underflow is used to create looping events, scoreboards, and other cool things. I have a save file that I'll release after v9 comes out that includes examples of how to use many different events.
There are some exciting new events that have been added, as well as some of the ones on the list have changed (for example, the minigame ones only work in a minigame now. You used to be able to reset the minigame of players who weren't in a minigame, which would cause them to respawn at the map spawn). You'll just have to see what made it in with the actual release.
One more thing, "Oops - Wedge slips out v9 events" is hardly flattering. We aren't kept from giving out details, we just reached a consensus a while ago that we were going to keep the newer content secret so people didn't try and copy it. The list I posted in the server was well before that.
In other news, tanks work now.
