Alert: chain fork caused by pre-0.8 clients dealing badly with large blocks

Hello everyone,

there is an emergency right now: the block chain has split between 0.7+earlier and 0.8 nodes. I'll explain the reasons in a minute, but this is what you need to know now:
  • After a discussion on #bitcoin-dev, it seems trying to get everyone on the old chain again is the least risky solution.
  • If you're a miner, please do not mine on 0.8 code. Stop, or switch back to 0.7. BTCGuild is switching to 0.7, so the old chain will get a majority hash rate soon.
  • If you're a merchant: please stop processing transactions until the chains converge.
  • If you're on 0.7 or older, the client will likely tell you that you need to upgrade. Do not follow this advise - the warning should go away as soon as the old chain catches up.
  • If you are not a merchant or a miner, don't worry.
