2022-02-08: Critical Security Update

IMPORTANT SECURITY UPDATE: This release fixes a critical security bug that made it possible to create ETH on Optimism by repeatedly triggering the SELFDESTRUCT opcode. While our sequencer and all infrastructure providers are already patched, please upgrade replicas to l2geth version 0.5.11 as soon as possible to avoid falling out of sync.

For more information about the bug, please see the disclosure.
