When going to purchase credits it still says this...so not sure if we're out or not...
"Please note: Glitch is a beta product and will be changing pretty dramatically over the next several months. These changes will be for the better, but they are changes nonetheless!All credit purchases during the beta period will be doubled once Glitch (re)launches (i.e., if you purchase 100 credits now, you will receive an additional 100 bonus credits after we launch)."
I think this indicates that we are almost out of beta. I am sure there will be an announcement and we will all get our bonus credits when we actually relaunch :)
