- Added support for uploading DATETIME, NANOTIMESTAMP, TIMESTAMP, and DATE scalars or vectors.
- Added support for uploading BOOL vectors.
- Improved the invoke function:
- Supported passing a function definition directly.
- Allowed undefined and null values as arguments when calling a functions with DolphinDB objects, booleans, or strings as parameters.

- Optimized the performance of invoke method.
- Fixed an issue where invoke failed to execute functions defined on remote nodes.
- Fixed disconnection issues when uploading strings with \0 to server.
- Added support for heartbeat mechanism to prevent automatic disconnection due to prolonged inactivity.
- Added function data() for converting DolphinDB data into primitive JavaScript data.
- Added function invoke() that allows passing parameters and returning execution results in primitive JavaScript data types when calling DolphinDB functions.
- Added function execute() that executes DolphinDB scripts and returns execution results in primitive JavaScript data types.
- Added support for serialization and deserialization of COMPRESSED vectors and Tensor form.
- Added support for subscription to HA stream tables.
- Enhanced support for documentation and function hints for the latest server version.
