I see that the most recent release states "Released on March 10, 2012". Is there any way to tell the date on the older versions? I have an older one, and don't see a date anywhere. Differences I see are that the graphics on the label are not the same, and that the cap on this year's version says CCB, while the older cap is blank. Sorry if this has been beat to death in other threads, but I couldn't find anything in my searches (except people saying that old Hunahpu's are drain pours).
