Scheduled

We are upgrading our Arbitrum-Stack chain infrastructure to Nitro v3.11.2.

This includes:
Gravity AlphaM
Robinhood
XAI
Arbitrum/Nova

This patch release includes a critical correctness fix for the Stylus warm-start cache that was not being rolled back when a transaction was dropped after execution, and a mutex fix for history reads to address concurrency issues.

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