This is the first release of TzGo that allows to send transaction. Our design is still in evolution and a few aspects will change before we craft a final release. We engineered all types and interfaces with maximum composability in mind. Start at essential low level types for public and private key handling, we added operation encoding/signing/broadcast and mempool/block monitoring. These features already sufficient to build end-user applications including the possibility to send smart contract calls, but may be less convenient. In a future release we will introduce higher order functionality that makes it easier and less verbose to send transactions and contract calls.
