Release v0.4.0

Fixed

• Interactions with the ledger service are now async. This fixes situations in which expensive ledger operations could starve the state machine loop.
• Ledger synchronization issue that happens when synchronizing the node during the second epoch.
• Correctly handle the situation in which the best tip changes during staged ledger reconstruction, causing the reconstruct to produce a stale result.
• Various edge cases in p2p layer (error propagation, disconnection, self-connection).

Added

• Support for identify protocol.
• P2P layer testing framework.
• Frontend: Block production page.

Removed

• Removed rust-libp2p based code, in favor of our own libp2p implementation.

Release v0.3.1

Changed

• Internal improvements to the actions logging mechanism.

Fixed

• Corrected sync stats for accounts fetching during ledger sync.
• Pruning of kademlia streams and requests.

Added

• Docker images tagged for each new release.
• Bootstrap process testing on CI.

Release v0.3.0

Changes

• Rust Toolchain: Updated the minimum required Rust toolchain to version 1.77.
• Networking:
  • Libp2p Replacement: Transitioned from libp2p to a custom internal networking implementation. The transition will be finalized in the next release, completely removing the libp2p dependency.
    • Gossipsub: Pending support. Current version of the node performs initial bootstrapping but cannot stay synchronized with network broadcasts.
    • Kademlia: Partial implementation includes bootstrapping and FIND_NODE server/client functionalities.
    • Identify Protocol: Absent in this release, rendering the node unusable as a seed node.
• Frontend:
  • Mobile Compatibility: Enhanced support for mobile platforms, improving user experience across various devices.

Fixes

• Staged Ledger: Resolved an issue where the ledger reconstruct step would block the state machine.
• Node Communication: Fixed a bug where nodes did not respond to ledger queries from bootstrapping peers, enhancing network cooperation.
• Frontend:
  • Test Stability: Addressed and fixed previously failing tests.
• Backend:
  • HTTP RPC: Corrected an error triggered when querying the /state endpoint.

Additions

• Bootstrap Efficiency:
  • Ledger Synchronization: Optimized the snarked ledger synchronization process during bootstrap, significantly reducing the time required.
  • Genesis Ledger Loading: Enhanced the loading mechanism for the genesis ledger, achieving much faster startup times.
• Frontend Enhancements:
  • Network Node DHT view.
  • Network Bootstrap Stats for real-time monitoring of network bootstrap statistics.
  • Main Dashboard view.
• Backend Improvements:
  • JsonPath Support: Enhanced the /state HTTP RPC endpoint with JsonPath support, offering more flexible state querying capabilities.

Release v0.2.0

Changed

• Default Rust toolchain switched to stable channel (as of 1.75).
• Internal refactoring to how leaf actions in the state machine are organized.

Fixed

• Node can now connect to the current berkeleynet after updates to:
  • Wire type definitions.
  • Verification, proving and circuits.
  • Ledger and transaction application logic.

Added

• Ledger tests on CI.

Release v0.1.0

Fixed

• Optimized scan state to reduce memory usage by avoiding duplication of data.
• Updated proof verification to be compatible with the current berkeleynet (rampup4).

Added

• Introduced support for producing proofs (blocks, payments, zkApp transactions, and merge proofs) compatible with the current berkeleynet (rampup4), with pending support for generating circuits.
• Added the ability to produce blocks (excluding user transactions) for testing purposes.
• Implemented pruning of inferior blocks post synchronization with the best tip.
• Enhanced the testing framework and debugging support as follows:
  • Improved compatibility with the OCaml node within the testing framework.
  • Introduced declarations for essential invariants to be verified by the test framework, simulator, and replayer.
  • Integrated SNARK worker into the simulator for SNARK production.
  • Added functionality to store dumps of blocks and staged ledgers for inspection upon block application failure due to mismatches.

Release v0.0.1

First public release.

Added

• Alpha version of the node which can connect and syncup to the berkeleynet network, and keep applying new blocks to maintain consensus state and ledger up to date.
• Web-based frontend for the node.
