- Hello again,
block 000000000000015c50b165fcdd33556f8b44800c5298943ac70b112df480c023 (height=225430) seems indeed to have cause pre-0.8 and 0.8 nodes to fork (at least mostly). Both chains are being mined on - the 0.8 one growing faster.
After some emergency discussion on #bitcoin-dev, it seems best to try to get the majority mining power back on the "old" chain, that is, the one which 0.7 accepts (with 00000000000001c108384350f74090433e7fcf79a606b8e797f065b130575932 at height 225430). That is the only chain every client out there will accept. BTC Guild is switching to 0.7, so majority should abandon the 0.8 chain soon.
Short advice: if you're a miner, please revert to 0.7 until we at least understand exactly what causes this. If you're a merchant, and are on 0.8, stop processing transactions until both sides have switched to the same chain again. We'll see how to proceed afterwards.

In short, they are asking miners to downgrade to v0.7 to make that chain longer than the problematic v0.8 chain.
UPDATE: Early this morning, a bitcoin block too big for version 0.7 was mined by miners using version 0.8, creating a fork in the blockchain. After some deliberation in the community, it was decided that miners should downgrade their version and continue the 0.7 fork until the issue is resolved. Also in order to avoid any possible problems we decided to temporally suspend all Bitcoin deposits on Mt.Gox until one of the blockchain wins. Please note however, that Bitcoin deposits with Mt.Gox or those in transit are safe and that once the situation is back to normal, we will resume Bitcoin deposits and that all deposits done in the meantime will be confirmed too. Finally we believe that this matter will be resolved within the end of the day for us in Japan. UPDATE: Bitcoin deposits have now been credited. Should you still have any further queries, please feel free to contact us at the Support. Our apologies for the inconvenience caused and thank you for your patience.Hello Mt.Gox Users,
