Highlights

There are not any significant features introduced in this release. But there are a couple of minor features and several dependency updates.

Ensure coroutines complete on workflow complete

Before, if a workflow function returned, nothing else that returned after it would be accepted even if it occurred in the same task (i.e. same event loop run before returning). Now, to better support update handlers and other coroutines, we allow all other coroutines to reach their yielded point upon main workflow method return and we make sure their commands are included before the workflow completion. Care was taken to ensure this is deterministic with workflows in older SDK versions by retaining the previous behavior for those.

Temporalio.Workflow.Semaphore

A lightweight, workflow-safe alternative to SemaphoreSlimis now available as Temporalio.Workflow.Semaphorefor use within a workflow.

Workflow update improvements

Can access update info inside update handlers and there is now a special exception thrown from update client calls when an the RPC is cancelled or times out.
