We are upgrading our Ethereum Mainnet & Testnets beacon infrastructure to Lighthouse v8.2.1.

This is a high-priority security release

The release also includes bug fixes for partial data column handling (EIP-8136) and performance optimisations around proposer preparation. No database schema migration or breaking changes are required. During the maintenance window, brief interruptions to RPC availability may occur.
