Click on the top tab and hit the beta button. It may take a couple times to make these tabs appear.
This should work assuming you have the original garrysmod on your steam account and if not it may still work.

*This was written as I didn't seen any article about it on D-Toid and also as a general heads up, apologies if it's duplicate news however*
And for those of you who got bored the New Beta Added support for Portal 2 and Left 4 Dead 2 in Garrysmod. (Although I tried Portal 2 and it wasn't working but that's probably since I haven't played coop yet.)
