v3.11.0-rc.3 - 2026-06-08

Changed

• Replace sha3/digest keccak with tiny-keccak across prover and caller-env.

Fixed

• Fix invalid Prometheus metric names in filtering-report and transaction-filterer components; hyphens in geth metric paths survive the /→_ translation and produce names that violate the Prometheus spec.
• Removed legacy validator (was included but not working since wasmer upgrade).
• Removed unnecessary tokens from consensus machine downloads in Dockerfile.

Internal

• NIT-5012: fail fast when delayed-sequencing filtering is active but transaction-filterer-rpc-client.url is unset, and pin the transaction-filterer binary to serve only the transactionfilterer RPC namespace.
• Make GuestPtr field private with checked addition (panics on overflow instead of silent wraparound).
• Remove JIT wrappers for arbcrypto and arbcompress.
