Into the Woods (1.4.13)

This patch is a hotfix release to mitigate last weeks DoS attacks, and those ongoing currently against Geth nodes in the network.

This patch should still be considered bleeding-edge. We advise exchanges and other users running business-critical applications that intend to run this release to simultaneously run a different client node and trigger a circuit breaker in case there is another DoS vulnerability or consensus failure. Users should continue to be on the alert for new patches and attacks against the network. Once enough nodes run the patch and the situation sufficiently stabilizes we will advise miners to slowly raise the gas limit.

There will be an additional patch created over the next several weeks to implement some more permanent fixes including cache journaling and cache-miss mitigation.
