Highlights
Converter Hints
Most places that affect data conversion to/from types can now have a "hint" set which is passed to the payload converter. These hints are not used by the default converters, but custom converters may leverage them to know more about the (de)serialization they should perform.
Task Queue Priority Support (experimental)
Task queue priority annotations are present to set workflow/activity tasks with specific priorities. This is to support the new server-side task queue priority feature which is still experimental.
Worker Versioning (experimental)
Worker versioning details can be set for workflow/activity/worker options. This is to support the new server-side worker versioning feature which is still experimental.
Poller Auto-scaling
Options for automating poller scaling are now available for workers.
Activity Pause (experimental)
Activities are interrupted via cancellation mechanisms when paused. This is to support the new server-side activity pause feature which is still experimental.
