1.12.0

PyPI

Highlights

• Memos can be added and modified inside a workflow by calling upsert_memo method.
• Executing local activities which do not exist will fail the workflow task instead of the activity
• Application failures can specify a category to control logging and metrics behavior of activity failures
• Activities can be paused via temporal activity pause, which will interrupt the activity's execution with a cancel-like exception

💥 Breaking Changes

• static_details and static_summary properties on WorkflowExecutionDescription are now async methods
• The worker options max_concurrent_workflow_tasks and max_concurrent_workflow_task_polls (or workflow_task_poller_behavior using SimpleMaximum) must be at least two. Previously this would silently cause issues, now it is a hard error at worker startup time.
