Key updates included the [Flow JVM SDK](https://github.com/onflow/flow-jvm-sdk) version 2.1.1 release:

1. Update FlowAccessAPI models to match latest version of Flow protobuf ( **non-breaking changes** ). This update returns a more thorough Access API response with additional fields for the below classes:

- `FlowBlockHeader`
- `FlowBlockSeal`
- `FlowBlockPayload`
- `FlowCollectionGuarantee`
- `FlowTransactionResult`
- `FlowNodeVersionInfo`, `FlowCompatibleRange`

1. New FlowAccessAPI/AsyncFlowAccessAPI methods added, along with runnable examples for each **(non-breaking changes):**

- `GetAccountBalance`
- `GetSystemTransaction`, `GetSystemTransactionResult`
- `GetExecutionResultById`
- `GetAccountKey`
- `GetCollectionById`, `GetFullCollectionById`
- `GetProtocolStateSnapshotByBlockId`, `GetProtocolStateSnapshotByHeight`
- `GetTransactionResultByIndex`

Runnable examples for each of the new endpoints can be found at: [flow-jvm-sdk/kotlin-example at main · onflow/flow-jvm-sdk · GitHub](https://github.com/onflow/flow-jvm-sdk/tree/main/kotlin-example) (Kotlin).

We anticipate to add support for updated Access API streaming methods in Q1 2025, pending web socket changes in the flow-go access node.
