New Features

• Subagent transcript helpers: Added list_subagents() and get_subagent_messages() session helpers for reading subagent transcripts, enabling inspection of subagent message chains spawned during a session (#825)
• Distributed tracing: Propagate W3C trace context (TRACEPARENT/TRACESTATE) to the CLI subprocess when an OpenTelemetry span is active, connecting SDK and CLI traces end-to-end. Install with pip install claude-agent-sdk[otel] for optional OpenTelemetry support (#821)
• Cascading session deletion: delete_session() now removes the sibling subagent transcript directory alongside the session file, matching TypeScript SDK behavior (#805)

Bug Fixes

• Empty setting sources: Fixed setting_sources=[] being silently dropped (treated as falsy), which caused the CLI to load default settings instead of disabling all filesystem settings. An empty list now correctly passes --setting-sources= to disable all sources (#822)

Internal/Other Changes

• Updated bundled Claude CLI to version 2.1.111
