## What happened

OP Labs published op-batcher v1.17.0 as a required operator release, including batch-transaction gas handling compatible with the L1 Glamsterdam transition.

## What changed

The released software changes L1 submission gas limits, permits configurable AltDA input limits, and removes the l2_network startup-log field.

## What did not change

The release does not establish an executed OP Mainnet deployment or a change to bridge permissions or withdrawal challenge periods.

## Confirmed

- The official release labels the upgrade required for op-batcher operators.
- Batch submission gas handling is designed to work before and after the L1 transition.
- Omitting the new AltDA configuration preserves the previous input-size limit.

## Still open

- OP Mainnet operator adoption and production readiness through the L1 transition are not established by this release.
- No bridge outage or withdrawal impairment is demonstrated.

## What it means for an advisor

- Review the optimism-bridge operational dependency file for operator upgrade readiness and batch submission continuity.
- Record deployment verification separately before treating the compatibility change as operative.
