Breaking Changes

●Issue #1

useTask() and useVisibleTask() now await their cleanup functions before running the next invocation. To prevent this awaiting behavior, do not return a cleanup Promise from these functions (and ensure errors are handled manually).

Migration Steps

  1. 1
    Review usages of useTask() and useVisibleTask(). If you were returning a cleanup function that returned a Promise, and you do not want the next invocation to wait for it, modify the cleanup function to return nothing or a non-Promise value.

Release Summary

This release introduces the Each component and splits the optimizer into a separate package to reduce download size. A major breaking change affects useTask/useVisibleTask cleanup functions, which now await cleanup Promises by default.
