## Human Summary
OpenAI Agents SDK 0.18.3 makes task and turn tracing configurable while fixing session, handoff, retry, and concurrent computer-provider isolation issues.

## Agent Summary
Evaluate the 0.18.3 upgrade when you need configurable trace spans, safer concurrent runs, reliable retries, or consistent session and handoff history.

## Body
This release is operationally meaningful for teams running agents concurrently or depending on trace data in production. Configurable task and turn spans reduce observability noise, while fixes around session initialization, handoff history, streamed retries, and provider isolation address failure modes that can otherwise be intermittent and difficult to reproduce.
