Scheduled

We are upgrading our Stellar Mainnet and Testnet RPC infrastructure to v27.1.0.

This release includes new API capabilities for transaction simulation and health monitoring, along with performance improvements and bug fixes.

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

RPC Changes:
- simulateTransaction — New optional `UseUpgradedAuth` flag enables opt-in support for the `AddressV2` authorization scheme in transaction simulations.
- getHealth — Response now includes `latestLedgerCloseTime` and `oldestLedgerCloseTime` (unix timestamps in seconds), allowing users to assess ledger freshness without fetching full ledger metadata.
- simulateTransaction — Now returns the ledger's close time rather than the execution timestamp to accurately reflect simulation state.
