v1.12.4

Partial blocks

Added experimental support for partial blocks (e.g. Flashblocks on Base)

See https://docs.substreams.dev/reference-material/chains-and-endpoints/flashblocks for details about how they work in Substreams.

• SUBSTREAMS_BIGGEST_PARTIAL_BLOCK_INDEX environment variable now specifies the index to use when bundling the "last partial block" from the full block. (default: 10, for Base)
• Added flag --include-partial-blocks on tools firehose-client

Bugfixes

• Substreams: fixed issue where "live backfiller" would not create segments after reconnecting with a cursor starting from a previous quicksave, causing delays in future reconnection
