## 2023-02-24, version 6.4.0
- Support transferable objects (#3, #374). Thanks @Michsior14.
- Implement a new callback `onTerminate` at the worker side, which can be used
to clean up resources, and an option `workerTerminateTimeout` which forcefully
terminates a worker if it doesn't finish in time (#353, #377).
Thanks @Michsior14.
- Pass `workerThreadOpts` to the `onTerminateWorker` callback (#376).
Thanks @Michsior14.

Argument `methods` is optional can can be an object with functions available in the worker. Registered functions will be available via the worker pool.
The following options are available:
- `onTerminate: ([code: number]) => Promise.<void> | void`. A callback that is called whenever a worker is being terminated. It can be used to release resources that might have been allocated for this specific worker. The difference with pool's `onTerminateWorker` is that this callback runs in the worker context, while `onTerminateWorker` is executed on the main thread.
