glamsterdam-devnet-4
liveAnnouncements
- 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](https://github.com/ethereum/execution-apis/pull/796) ↔ [consensus-specs#5235](https://github.com/ethereum/consensus-specs/pull/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).
