The Authority Node Operator Luciap
released version 1.1 of factom.js today. New features:
1. A new Factom blockchain event emitter. This is a great addition made by Alex of Factoshi which simplifies a lot writing applications that react to on-chain events (new blocks, new entries, new transactions etc).
2. Proper support for chain and entry EC signature delegation. This is useful to allow external devices storing your EC keys to pay for the entry. Think hardware wallet integration or IOT device integration.
