            The following PRs were merged in [microsoft/agent-framework](https://github.com/microsoft/agent-framework) since the last workflow run and may require documentation updates in this repository.

            ## PRs to Process

            ${prSummary}

            ## PR Details

            ${prDetails}

            ## Acceptance Criteria

            Follow the instructions in \`.github/agents/agent-framework-pr-merge.agent.md\` to:

            1. **Analyze each PR** to determine if documentation updates are needed
            2. **Update relevant documentation** in \`agent-framework/\` for any API or behavior changes
            3. **Add Python breaking changes** to \`agent-framework/support/upgrade/python-2026-significant-changes.md\`:
               - Use the "Unreleased (Coming Soon)" section if the change is not yet in a published release
               - Include before/after code examples
               - Add entry to the summary table
            4. **Handle version updates** by converting "Unreleased" sections to the proper version header
