v1.4.0

Substreams RPC protocol V2

Substreams protocol changed from sf.substreams.v1.Stream/Blocks to sf.substreams.rpc.v2.Stream/Blocks for client-facing service. This changes the way that substreams clients are notified of chain reorgs.
All substreams clients need to be upgraded to support this new protocol.

See https://github.com/streamingfast/substreams/releases/tag/v1.1.1 for details.

Added

• firehose-client tool now accepts --limit flag to only send that number of blocks. Get the latest block like this: fireeth tools firehose-client <endpoint> --limit=1 -- -1 0
