What data range do you have for US stocks?

In http://www.quantconnect.com/data/Stocks#1.1.2, you have mentioned QuantConnect provides tick data on all US stocks back to January 1st, 1998. But up to what date?. I think the stops sometime in 2012?

I have been trying a simple dollar cost average on SPY (ETF), and just wondering whether you guys upload latest date from your vendors as of t-1.
