v1.5.0

Common

• Add sf.firehose.v2.EndpointInfo/Info service on Firehose and sf.substreams.rpc.v2.EndpointInfo/Info to Substreams endpoints. This involves the following new flags:
  • advertise-chain-name Canonical name of the chain according to https://thegraph.com/docs/en/developing/supported-networks/ (required, unless it is in the "well-known" list)
  • advertise-chain-aliases Alternate names for that chain (optional)
  • advertise-block-features List of features describing the blocks (optional)
  • advertise-block-id-encoding Encoding format of the block ID [BLOCK_ID_ENCODING_BASE58, BLOCK_ID_ENCODING_BASE64, BLOCK_ID_ENCODING_BASE64URL, BLOCK_ID_ENCODING_HEX, BLOCK_ID_ENCODING_0X_HEX] (required, unless the block type is in the "well-known" list)
  • ignore-advertise-validation Runtime checks of chain name/features/encoding against the genesis block will no longer cause server to wait or fail.

Substreams

• add --common-tmp-dir flag and activate local caching of pre-compiled WASM modules through wazero feature
• revert module hash calculation from v1.5.5, when using a non-zero firstStreamableBlock. Hashes will now be the same even if the chain's first streamable block affects the initialBlock of a module.
• add --substreams-block-execution-timeout flag (default 3 minutes) to prevent requests stalling

v2.0.0-rc.3

What's Changed

• set block version to 2 for v2 blocks by @fschoell in #153

Full Changelog: v2.0.0-rc.2...v2.0.0-rc.3

v2.0.0-rc.2

What's Changed

• include new accepted_block_v2 fields by @fschoell in #148

Full Changelog: v2.0.0-rc.1...v2.0.0-rc.2

v1.4.10

Substreams

• fix high CPU usage on tier1 caused by a bad error handling

v1.4.9

Substreams

• Prevent Noop handler from sending outputs with 'Stalled' step in cursor (which breaks substreams-sink-kv)

v1.4.8

Substreams

• Fixed a bug in substreams where chains with non-zero first-streamable-block would cause some substreams to hang. Solution changes the 'cached' hashes for those substreams. For more information see here.

Security

• Bump google.golang.org/grpc from 1.64.0 to 1.64.1 by @dependabot in #150

v1.4.7

Substreams

Important Substreams BUG FIX

• Fix a bug introduced in v1.6.0 that could result in corrupted store "state" file if all
  the "outputs" were already cached for a module in a given segment (rare occurence)
• We recommend clearing your substreams cache after this upgrade and re-processing or
  validating your data if you use stores.

Added

• Expose a new intrinsic to modules: skip_empty_output, which causes the module output to be skipped if it has zero bytes. (Watch out, a protobuf object with all its default values will have zero bytes)
• Improve schedule order (faster time to first block) for substreams with multiple stages when starting mid-chain

v1.4.6

• fix "hub" not recovering on certain disconnections in relayer/firehose/substreams (scenarios requiring full restart)

v2.0.0-rc.1

Antelope Spring

This is a first pre-release that supports decoding deep mind logs from the Antelope spring software. Note that this block format is not final yet and might still change in future versions.

v1.4.5

Substreams

• Added substreams back-filler to populate cache for live requests when the blocks become final
• Fixed: truncate very long details on error messages to prevent them from disappearing when behind a (misbehaving) load-balancer
