pydantic-ai 2.43.0 stops keying Temporal tool opt-out checks on an MCP import
The release published 2026-09-12 fixes the Temporal integration to decide tool opt-out by operation kind rather than by whether MCP was imported (PR #8257), which had made behavior depend on an unrelated dependency being present. It also preserves text part boundaries after tool calls in `OpenAIChatModel` (PR #8235), a correctness fix for anyone parsing interleaved text and tool output. The feature side is a single first-run banner describing the run in `clai` sessions.
