Highlights
Nexus
We have made some improvements in Nexus metrics, nexus_task_execution_failed is now tagged with a failure_reason to help users understand the cause of the task failure.
see also: https://docs.temporal.io/references/sdk-metrics#nexus_task_execution_failed
Test Environment
Improved support for mocking Nexus operations so you won’t need to have access to the operation itself or implementing a dummy operation. You can mock by calling OnNexusOperation and, when appropriate, RegisterNexusAsyncOperationCompletion.
Docs coming soon.
Worker shutdown
When a Go SDK worker s shutting down it will now communicate to the Temporal service through a new ShutdownWorker API that the worker is no longer taking more tasks. If the Temporal service supports this feature all sticky workflow tasks will be assigned back to the normal task queue. This should reduce latency caused by shutting down a worker due to stick task queue timeout.
