0.39.0

• Added: This release includes many new tools to better support Swift concurrency. See this discussion and this pull request for more information.

  Note: Many of the old Combine-centric interfaces have been soft-deprecated. Prefer using Effect.task, Effect.run, and Effect.fireAndForget as described in the documentation.

• Infrastructure: README, documentation, and demo app fixes (thanks @filblue, @Jager-yoo, @konomae, @yimajo).
