This Node and Miner patch release is recommended for all node operators and storage providers. It moves the FVM to wasmtime 48 LTS for performance and security improvements, fixes CreateBackup path containment, and makes Ethereum JSON-RPC quantity validation stricter. Review the upgrade warning before upgrading.
✨ Notable Changes
- ⚠️ Upgrade warning: Ethereum JSON-RPC rejects negative, unprefixed, leading-zero and oversized (>256-bit) big integers. Use canonical
0xencoding (0x0for zero). The Go helperapi.NewErrNegativeGasPriceis removed. (#13938) - The FVM now runs on wasmtime 48 LTS for every network version, via ref-fvm v4.9.0. Security: wasmtime 48 is a long-term-support release that gets security fixes until ~August 2028. Performance: on a mainnet node over 24 hours, median execution time per unit of gas fell about 18% for messages and 11% overall, with no regressions seen on mainnet or calibnet (measurements).
