### Minor Changes

- [#272](https://github.com/open-spaced-repetition/ts-fsrs/pull/272) [`23ec7a9`](https://github.com/open-spaced-repetition/ts-fsrs/commit/23ec7a947d305f2fb3055653052c43b253b43b9d) Thanks [@ishiko732](https://github.com/ishiko732)! - refactor(binding): refactor progress callback to support training interruption

  BREAKING CHANGES:

  - progress callback no longer supports async functions, because call\_with\_return\_value does not support asynchronous execution. See Node.js N-API documentation: [https://nodejs.org/api/n-api.html#n\_api\_napi\_call\_threadsafe\_function](https://nodejs.org/api/n-api.html#n_api_napi_call_threadsafe_function)

- [#309](https://github.com/open-spaced-repetition/ts-fsrs/pull/309) [`7c0d97c`](https://github.com/open-spaced-repetition/ts-fsrs/commit/7c0d97c8f60f0203e07282e6c23ec2adb54dc352) Thanks [@ishiko732](https://github.com/ishiko732)! - feat(binding): add `initOptimizer` dynamic loader for custom wasm/worker resources

  - Export `./dynamic-wasi` entry from `binding` with `initOptimizer(options)` for Node.js and browser
  - Export `./wasi-worker` and `./wasm` entries from `binding-wasm32-wasi` for resolving worker and wasm paths
  - Allows users to provide wasm binary (Buffer, URL, Response) and worker (factory, instance, path) externally
