What does the new GetVirtualChainFromBlockV2 API change for Kaspa integrators?

GetVirtualChainFromBlockV2 is a new API endpoint that returns virtual-chain updates together with per-chain-block accepted transaction data in a single call, replacing a workflow that previously required stitching together multiple asynchronous requests. Integrations can now retrieve sender and fee-relevant context directly, and the underlying DAG complexity is better abstracted away so that integrating Kaspa feels much closer to integrating a classic blockchain. It is a non-breaking addition — the existing GetVirtualChainFromBlock endpoint is unchanged, so nothing breaks for integrators who have not yet upgraded. For end users, this means the exchanges, wallets, and explorers built on Kaspa can display more complete and accurate transaction information with less engineering effort on the builder's side.
