Scheduled

We will be upgrading our Stacks Blockchain API nodes on both Mainnet and Testnet to version v8.11.2 on 2025-07-03 at 12:00 UTC.

This is a minor version upgrade from v8.11.1, and includes performance optimizations, improved endpoint stability, and small bug fixes to improve API consistency and data integrity across block indexing and transaction resolution.

No downtime is expected. However, short-lived API indexing delays may occur immediately following the upgrade.
