A second fork has followed the initial post BIP 66 fork further highlighting the continued danger of so called "soft" forking changes to the consensus code of Bitcoin network clients. The second fork persisted from 21:50 through to 23:40 on July 5th, 2015. Implementing the rather non-controversial change proposed by BIP 66 to enforce strict DER encoding on ECDSA signatures has without a doubt increased the fragility of the Bitcoin network such that users of all Bitcoin clients ought to consider waiting beyond the traditional 6 mined blocks before considering a transaction confirmed. Unless all major miners begin mining with fully validating node software, this instability is likely to continue indefinitely into the future with users of the latest versions of "Bitcoin Core" at risk of finding themselves stranded, maybe even permanently on the short side of an enduring fork.
