Armory is not compatible yet with 0.11.1. Newest Bitcoin Core enforces LowS while Armory signs HighS. Users are reporting they are unable to send bitcoin using Armory after upgrading Bitcoin Core 0.11 to 0.11.1 and had to downgrade.
CircusPeanut merged the fix into 0.93 and etotheipi and I have reviewed the code. It should be going public soon enough.
