[Standard] Stacks Mainnet and Testnet - Upgrade stacks-blockchain-api to v9.2.0

Scheduled for Sep 17, 00:00 - 04:00 UTC

Scheduled

We are upgrading our Stacks Mainnet and Testnet API infrastructure to stacks-blockchain-api v9.2.0. This release introduces three new v3 API endpoints for batch transactions, staking bond events, and staking rewards totals, and fixes a bug in Bitcoin rewards counting that incorrectly mixed PoX reward distribution amounts with burned amounts.

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

RPC Changes:
- Batch transactions endpoint (v3) — New endpoint added for querying batch transaction data.
- Staking bond events endpoint (v3) — New endpoint added for retrieving staking bond event information.
- Staking rewards totals endpoint (v3) — New endpoint added for querying aggregated staking rewards data.
- Bitcoin rewards — Bug fix corrects the count and distribution of Bitcoin rewards; responses from rewards-related endpoints will now reflect accurate PoX amounts separate from burned amounts.
