[Standard] Ethereum Mainnet and Testnets - Upgrade to Reth v2.5.2

Scheduled for Sep 16, 01:00 - 05:00 UTC

Scheduled

We are upgrading our Ethereum reth infrastructure to v2.5.2. This upgrade includes maintenance improvements from v2.5.1 and v2.5.2, including a fix for a startup issue that could occur after finalization leaves gaps in write-ahead logs, improved handling for networks with dynamically scheduled forks to update their fork configuration without a restart, more reliable payload building when a build resolves early, a fix for how storage data is handled during batched persistence, and internal file-handling and logging improvements.

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

This release does not include any changes to end-user facing RPC methods or API behavior.
