v1.7.1

Added

• substreams-dev: new references/performance.md (docs "Performance Guidelines": few modules, few independent stores, substreams::skip_empty_output(), late initialBlock, check-before-decode, bytes until db_out, int64/float64 stores, no logging in loops, EVM eth_call and Solana notes) and references/updating-packages.md (docs "Updating Your Substreams": what feeds the module hash, use: / previous-binary options, substreams tools extract-wasm / unpack, hash comparison with substreams info).
• substreams-dev manifest-spec.md: use:, foundational-store: input, protobuf.descriptorSets, binaries[].build, wasm-bindgen-shims, registry import forms and env-var expansion, set_sum.
• substreams-sink: RPC protocol v4 / S2 compression notes and partial blocks (Flashblocks) rules. substreams-sink-deploy-local: standby sinks (--standby-lock, --stall-timeout). substreams-sql: invalid UpdateOp sequence and composite-key / fix. substreams-solana: versioned transactions (substreams-solana >= 0.15.1). substreams-testing: module cache only in production mode; cache state when benchmarking.

Changed

• Block filtering now leads with a foundational index: raw Block input + blockFilter on ethereum_common:index_events / solana_common:program_ids_without_votes. A custom blockIndex is only advised when several modules filter on it; filtered_* modules are an alternative (extra module, no tx context; params override still mandatory). Notes that blockFilter is block-level, so keep a cheap in-handler address/program check. Touches substreams-dev, substreams-ethereum, substreams-solana, substreams-convert.
• substreams-dev: reverses "smaller, focused modules perform better" — the docs say keep the module count small and split only for cross-package reuse.
• substreams-solana / substreams-dev: blocks_without_votes is no longer recommended; StreamingFast Solana endpoints no longer serve vote transactions.
• Short registry imports (name@version) are documented as working on CLI >= 1.20.0 (older CLIs still need the full spkg.io URL) instead of "always 404".
• substreams-ethereum: eth_call guidance now prefers trace data and the ERC20 Token Metadata Foundational Store (Ethereum mainnet only) before RPC + cache stores.

Fixed

• manifest-spec.md: package.image is the registry icon path (JPEG/WebP/PNG, <= 2 MiB), not a container image.
