Beta 0.68 has been released, for BMTMicro customers it’s available right now, Desura customers need to hang in there for a small while for Desura staff to verify that the update is working can now access the update as well.
Here’s the change log for 0.68, briefly put, it includes several crash fixes in online, improved vehicle collision detection, vehicle spawn spots (map3 only now, more and better placed spots in the next version — but hey, you can always mod the maps to place the spots where you’d want them ), and support for designated bases mainly for the PvP maps.
If your beta 0.67 game is telling you to “use your download link” in the menu, just disregard it, BMTMicro customers know what it means and this particular piece of text is gone starting from 0.68.
