Mojang released a 1.8 Pre-release! Get it here! I have setup a server at port 25565.
The world of that server will be deleted once the final version is out.
we built basic shelter @ -36 / -23
I also created a map here: http://minecraft.uncovery.net/map/temp.png
If you are a new user there is a high chance that you cannot connect to the 1.8 server. The whiltelist does not update automatically but only on restarting the server.
