sdk-python/v1.43.0

Breaking Changes

• Removed Client.trigger_continue_as_new, AsyncClient.trigger_continue_as_new, FlowStatus.CONTINUED_AS_NEW, FlowConfig.continue_as_new_threshold, FlowConfig.continue_as_new_page_size_bytes, and include_continued_as_new from both clients' search_flows methods. Reference.
• FlowConfig is a dataclass, and the two removed fields were its second and third fields. Every later field moves two positions forward, so a positional FlowConfig call can set the wrong field. Construct FlowConfig with keyword arguments. Reference.
• Removed WaitForStepCompletionOptions.internal_handler_timeout and WaitForAttributeOptions.internal_handler_timeout. request_id remains accepted but the server does not read it for these waits. Reference.
• Generated bindings rename FlowExecutionID to FlowRunID and flow_execution_id to flow_run_id. ProtoJSON uses flowRunId. Reference.
