Release v0.15.0

Added

• Restored support for snark workers.
• Archive: Support for storing blocks to AWS, GCP and filesystem.
• Tooling: WebRTC traffic sniffer.
• GraphQL:
  • sendPayment mutation.
  • sendDelegation mutation.
  • pooledUserCommands query.
  • pooledZkappCommands query.
  • Various other partially implemented queries expanded to ensure compatibility with the OCaml node.

Changed

• P2P: Wait until full validation is complete before broadcasting transactions and completed works.
• Transition frontier: Perform cheap consensus operation first, and then the more expensive proof verification.
• Transaction pool: Unified libp2p and webrtc logic for the initial phase of handling transactions received from gossip network. As a result, processing of transactions received during bootstrap is delayed until the initial sync is complete.
• Transaction pool: Suspend processing during block production.

Fixed

• Transition frontier: Rare race condition in the case of forks during block production that could result in dropping staged ledgers too early.
• Webnode: Replaced tokio channels which had a race condition that could crash the thread on WASM.
• Transaction pool: Verify zkApp proofs in a dedicated thread to avoid blocking the state machine.
