Six Months since release. Not a single real content patch?

The game came out on Dec 16th. This is the sixth month anniversary. I played the heck out of this game at release. I love it and I think it was worth the cash already.

After six months though I'm a little baffled. I didn't expect much but here's the only new content listed in patch notes:

• Dynamite
• Research tree reshuffling (good but not much beef there)
• Augment for Terrain tools.

That's it right? Did I miss something? I'm not trying to bash the devs because they're obviously doing hard work on lots of things. I'm just wondering when the new content is coming.
