Announcements

bal-devnet-7 target launch: Monday 18.05 (subject to ACDT today).
Last bal- prefixed devnet. Consolidates the bal-devnet-3 optimisations with the EIP-8037 spec changes finalised since bal-devnet-6 — confirmed in tests-bal@v7.0.0. Future devnet releases will be prefixed glamsterdam-.
EIP-8037 final shape — all spec changes for the EIP land here, pulled from four EIPs PRs: #11573 (fixed CPSB + frame accounting, merged), #11606 (SELFDESTRUCT charges, merged), #11611 (bal-devnet-6 bug fixes, open), #11616 (parameter recalibration, open). EELS reference branch: devnets/bal/7.
Parameters: cost_per_state_byte 1174 → 1530 (fixed), STATE_BYTES_PER_NEW_ACCOUNT 112 → 120, STATE_BYTES_PER_STORAGE_SET 32 → 64, STATE_BYTES_PER_AUTH_BASE unchanged at 23. SYSTEM_CALL_GAS_LIMIT raised from 30M to 30M + STATE_BYTES_PER_STORAGE_SET × CPSB × SYSTEM_MAX_SSTORES_PER_CALL (SYSTEM_MAX_SSTORES_PER_CALL = 16); the extra is allocated to state_gas_reservoir so system calls cannot OOG on state-gas growth alone.
eth/70 (EIP-7975) and eth/71 (EIP-8159) are now mandatory — moved from optional after the SFI check in #block-access-lists (2026-05-08). Every EL must support both for bal-devnet-7.
