EOS - Dawn 3.0 has arrived! EOS.IO - The Most Powerful Infrastructure for Decentralized Applications
Major changes in Dawn 3.0 include changing “eos” to “eosio” in all locations throughout the code. We have also renamed "message" to "action", and removed the need for developers to manually specify 'scope'; all scope specification is now automated
Smart contracts written for the Dawn 2.x codebase will need to be revised to work on the new 3.0 codebase and take advantage of the new features.
