I'm hoping Woltlab doesn't use any of Yahoo's YUI code. I know a lot of other developments that fallback on. I've been telling people for sometime now that this was going to happen, but quite a few people on other sites didn't want to hear it or believe it as they had this 'to big to fail' mentality. But fail it has.
Yahoo is officially discontinuing the YUI framework (all version) and not going to develop it any further.
