glamsterdam-devnet-5
liveAnnouncements
- glamsterdam-devnet-5 targets to launch on 4th of June 2026 and shut off on 25th of June 2026.
- **First `glamsterdam-` prefixed CL+EL devnet** combining `consensus-specs` **v1.7.0-alpha.10** 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).
