Bitcoin XT is released
Mike Hearn and Gavin Andresen released Bitcoin XT, a version of Bitcoin's software that would raise the block size limit to 8 MB under BIP 101 once three quarters of recent blocks supported it. It never reached that level of support.

The value overflow incident, 2010
5 years ago. A transaction in block 74,638 created about 184 billion bitcoin by exploiting a bug in how the software added up large amounts. Satoshi Nakamoto released a fix, Bitcoin 0.3.10, the same day, and the network replaced the bad block.
