Announcements

glamsterdam-devnet-4 targets to launch in late May 2026.
First glamsterdam- prefixed CL+EL devnet combining consensus-specs v1.7.0-alpha.8 with the bal-devnet-7 EL feature set, plus the new targetGasLimit engine API field (execution-apis#796 ↔ consensus-specs#5235).
targetGasLimit on PayloadAttributesV4 — CL now passes the per-validator target gas limit to the EL on engine_forkchoiceUpdatedV4, replacing the static EL-side flag. CL also enforces target_gas_limit consistency with the block's gas_limit (CL PR-5236).
EIP-8037 final shape: cost_per_state_byte 1174 → 1530 (fixed), STATE_BYTES_PER_NEW_ACCOUNT 112 → 120, STATE_BYTES_PER_STORAGE_SET 32 → 64. SYSTEM_CALL_GAS_LIMIT raised so system calls can't OOG on state-gas alone. Reference block gas limit raised 96M → 150M.
eth/70 (EIP-7975) and eth/71 (EIP-8159) are now mandatory — every EL must implement both (promoted from optional in bal-devnet-7).
