Changelog

• Tested with cardano-node 9.1.1 and cardano-cli 9.2.1.0

• Switch L2 ledger to use the Conway era. #1178

  • Conway formatted transactions can be submitted to the hydra-node, while past eras are still supported (except deprecated features like protocol updates).
  • This includes support for PlutusV3 scripts, but most of the governance-related features have no meaning in the Hydra L2.

• Added head id information into the Greetings message.

• Adds a manual recipient address entry to hydra-tui and fixes event handling. #1607

• Add a demo mode to hydra-cluster to facilitate network resiliance tests #1552
