[Standard] Hedera Mainnet & Testnet - Mirror Node v0.160.1

Scheduled for Aug 12, 00:00 - 06:00 UTC

Scheduled

We are upgrading our Hedera Mainnet Mirror Node infrastructure to v0.160.1.
This patch release fixes a critical infinite loop bug in the FixEvmTransactionIndexMigration that could cause startup delays or synchronization failures.

The underlying v0.160.0 release corrects EVM transaction index ordering to include only top-level EVM transactions; child transactions now inherit the index of their parent. This migration is asynchronous and runs in the background.

Brief interruptions to RPC availability may occur during the upgrade window.
