[Standard] Optimism-Stack Chains - Mainnets and Testnets - Upgrade op-node to v1.19.2

Scheduled for Jul 15, 09:00 - 17:00 UTC

Scheduled

We are upgrading our Optimism-Stack Chains (Opti, Unichain, Ink, Soneium, Mode, Zora) infrastructure to op-node v1.19.2.

This release fixes a critical issue encountered when op-node operates with execution layer clients that prune historical block bodies (such as op-reth with `--minimal` or `--prune.bodies.distance` flags), and improves tolerance for expired genesis history during L2 config validation.

During the maintenance window, brief interruptions to RPC availability may occur.
