The link to the 0.0.3 beta was posted in the shout box. It only displays the last 100 entries so you will have to wait until they put it there again and hope you are online and see it.
And nobody thought about putting it on a server and put the link in a topic ? ;(
I know, right? I think they thought that they’d have a new release ready by end of day yesterday so they held off, but that didn’t happen. Maybe they don’t want that Beta getting out to too many people.
