v1.47.0

Highlights

• User metadata fields (StaticSummary, StaticDetails, CurrentDetails, Activity Summary, Timer Summary, AwaitOptions) are no longer marked as experimental.
• Workers automatically enroll into poller autoscaling when the namespace advertises the PollerAutoscalingAutoEnroll capability. This only applies to poller types left at their default; explicitly configured pollers are left unchanged.
• Added worker.Options.PreferredVersionProvider, which can select the version recorded by a newly encountered workflow.GetVersion call. This supports gradual rollout of a new GetVersion call before activating its new behavior.
• Added nexus support for workflow updates and external storage.
• Numerous bug fixes: see CHANGELOG.md for details.
