v1.11 (Technology Preview)

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.
  • extended package tezos with private key and message signing support
  • refactored transaction parameter encoding in micheline
  • new package codec for encoding Tezos operations
  • Refactored and extended package rpc
    • New: POST requests to forge, simulate and broadcast operations
    • New: use interface type BlockID where a historic block may be specified, can either be
      • BlockAlias (genesis or head)
      • BlockLevel an int64
      • tezos.BlockHash for named blocks
      • BlockOffset for offsets from a BlockID
    • New: MempoolMonitor to monitor new mempool transactions
    • Refactored Mempool type to return the same Operation type like block calls
    • Refactored contract, rights and vote calls for consistent naming and parameters
    • Refactored operations
      • renamed OpKind() into Kind()
      • renamed RevelationOp into Reveal and removed ..Op suffix from all types
      • renamed Origination.Manager() into Origination.ManagerAddress()
      • unified operation metadata and results
      • added helpers to extract metadata, result and costs from typed interface
