Scheduled

We are upgrading our Hedera Mainnet and Testnet infrastructure to Hiero Mirror Node v0.161.2.

This release contains a bug fix that excludes null transaction_index values from the contract results endpoint, ensuring data consistency in contract query responses.

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

RPC Changes:
- contract results endpoint — Records with null transaction_index values are now excluded from responses, correcting a data filtering issue that previously returned incomplete or inconsistent contract result data.
