Executive summary sir:

There was a threat.

To the extent that the threat was credible, it was mitigated in the code.
During the mitigation, most exchanges stopped transacting with the monero block chain, but kept exchanging openly.
There were some brief DDoS attacks and minor alerts, but no substantial problems

Business as usual resumed shortly after the mitigation work was completed, with some nice enhancements to the code that prevent this sort of threat from reoccurring. 

Lessons learned discussions are still ongoing but at minimum, the enhancements are sufficiently innovative that they may be adopted by all other coins to prevent this type of threat in a distributed fashion.  This is a win for crypto currency in general.
