NKN MainNet v2.2.1 Release

We released a new mainnet version v2.2.1 at https://github.com/nknorg/nkn/releases. This version supports WebRTC for client-node communication. WebRTC will be used to replace WSS for JavaScript clients running in https environments. It is the final and most important step towards fully decentralized communication in browsers. In addition, this version contains several performance optimization, bug fixes and security patches. Upgrade is required to support new WebRTC clients.
