2. Is BIP68, BIP112, and BIP113 integrated? If so when is the activation date?
Yes, depends on miners, but in the next few days I believe.
The final 1.6.0 soft fork has now kicked in, all of the above is officially active.
You guys have thought of everything but I do think your too humble with your achievements. I don't believe in hyping but Gulden team is certainly under selling the 1.6.0 update and under selling is a under statement in this case.
