Set up a node with 1.1 daemon, sync working to height 31475 (current max)
Running nodes with 1.2 daemon, sync working to the same height.
Blocks mined by pool seem to be accepted by other nodes. Transactions broadcasted at cca 31000 by our nodes were mined by the pool too. If your node sees this chain orphaned, please re-sync.
Testing old and new simplewallet against both versions of daemon and will post results here later.
