Migration

v2 to v3

v3 is React concurrent mode safe. There will be no synchronous subscription.

1. If synchronous values from observables are used as initial state, move the initialization logic to the initialState parameter of useObservableState, useObservablePickState and useObservableGetState.
2. useGetObservableState and usePickObservableState signatures are incompatible. The new added initialState is not optional.
3. If initialState is a function it will be called. If you need to use function as state wrap it with an extra function.

v3 to v4

v4 is not compatible with TypeScript 3.

1. remove the readonly modifier of useObservable and useLayoutObservable dependency list.

v3.0.0 to v4.2.0

1. Errors in Observable will not be automatically re-thrown to Error Boundary. Use useRenderThrow explicitly.
