This version replaces all previous versions. Any prior version will stop working on 2021-05-06T00:00:00Z. Node administrators must upgrade to this version before that date.

This version will stop working on 2021-06-17T00:00:00Z.

Changes:

  • Improve P2P networking configuration. (#1174)

    • Re-add builtin bootstrap nodes. This also means that default bootstrap nodes will be used as long as --ignore-boostrap-nodes (or the respective configuration file setting) is not enabled.
    • Add X-Peer-Addr response header that allows nodes to auto-discover their external network configuration.
    • Enable chainweb-node to auto-configure the hostname when the hostname is set to '0.0.0.0'. This eliminates the need to use a (centralized) third party service for that.
    • Validate P2P configuration on startup.
    • Validate peer configuration on startup.
    • Check that a chainweb-node can connect with a configurable portion of the known-peers and bootstrap nodes at startup. The portion can be configured via the --bootstrap-reachability option or the chainweb.p2p.bootstrapReachability setting. The value is a number between 0 and 1. If it is 0 the reachability test is disabled.
  • Remove deprecated mining coordination code. (#1177)

    • Removes support for public mining.
    • Fix two race conditions in the mining API that may have slightly increased the number blocks that got orphaned before being included on the chain.
  • Internal infrastructure to support bridging KDA to other networks (#1210)

  • New OpenAPI 3.0 specification of the chainweb-node API. The API documentation is maintained in the git repository https://github.com/kadena-io/chainweb-openapi. It is published at https://api.chainweb.com/openapi.
