**

This release contains breaking changes to the Block#Header, specifically NumTxs and TotalTxs were removed (#2521). Here's how this change affects different modules:

  • apps: it breaks the ABCI header field numbering
  • state: it breaks the format of State on disk
  • RPC: all RPC requests which expose the header broke
  • Go API: the Header broke
  • P2P: since blocks go over the wire, technically the P2P protocol broke

Also, blocks are significantly smaller 🔥 because we got rid of the redundant information in Block#LastCommit. Commit now mainly consists of a signature and a validator address plus a timestamp. Note we may remove the validator address & timestamp fields in the future (see ADR-25).

Special thanks to external contributors on this release: @erikgrinaker, @PSalant726, @gchaincl, @gregzaitsev

Friendly reminder, we have a bug bounty program.

BREAKING CHANGES:

  • CLI/RPC/Config

    • [rpc] #3471 Paginate /validators response (default: 30 vals per page)
    • [rpc] #3188 Remove BlockMeta in ResultBlock in favor of BlockId for /block
    • [rpc] /block_results response format updated (see RPC docs for details)
      {
        "jsonrpc": "2.0",
        "id": "",
        "result": {
          "height": "2109",
          "txs_results": null,
          "begin_block_events": null,
          "end_block_events": null,
          "validator_updates": null,
          "consensus_param_updates": null
        }
      }
      
    • [rpc] #4141 Remove #event suffix from the ID in event responses. {"jsonrpc": "2.0", "id": 0, "result": ...}

      id=0 method=/subscribe
      id=0 result=...
      id=1 method=/abci_query
      id=1 result=...
      
      • ID is unique for each request;
      • Request.ID is now optional. Notification is a Request without an ID. Previously ID="" or ID=0 were considered as notifications.
    • [config] #4046 Rename tag(s) to CompositeKey & places where tag is still present it was renamed to event or events. Find how a compositeKey is constructed here
