• ✅ src/orchestrators/collab-orchestrator/orchestrator - Updated all dependencies (33 tests passed)
• ✅ src/orchestrators/workflow-orchestrator/orchestrator - Updated with Python version requirement change

Major Version Updates:

• semantic-kernel: 1.33.0 → 1.37.0 (4 minor versions)
• a2a-sdk: 0.2.4 → 0.3.7 (breaking changes addressed)
• dapr-ext-workflow: 0.5.0 → 1.16.0 (major version jump)
• opentelemetry-* packages: 1.29.0 → 1.37.0

Breaking Changes Fixed:

• a2a-sdk API changes: Updated import path from a2a.server.apps.starlette_app to a2a.server.apps.jsonrpc.starlette_app
• a2a-sdk field naming: Changed from camelCase to snake_case (documentationUrl → documentation_url, pushNotifications → push_notifications, etc.)
• Python version: Updated workflow-orchestrator from >=3.11 to >=3.12 for consistency with other components

Type of Change

• Other (please specify): Dependency maintenance - comprehensive package updates

Human Review Checklist

⚠️ Critical Items to Verify:

1. a2a-sdk Breaking Changes: Search codebase for any remaining references to old a2a-sdk patterns:
   • Old import: a2a.server.apps.starlette_app
   • Old field names: documentationUrl, pushNotifications, defaultInputModes, etc.
2. Python 3.12 Requirement: Confirm that updating workflow-orchestrator from Python >=3.11 to >=3.12 is acceptable for your deployment environments
3. Major Version Impacts: Review if semantic-kernel 1.33.0→1.37.0 introduces any functionality changes that affect your use cases

📋 Additional Review Points:

• Verify university agent can still start successfully with updated semantic-kernel
• Check that Gemini completion factory remains compatible
• Consider if additional integration testing is needed given the scope of updates
• Review if any documentation needs updating for new dependency versions

Additional Comments

All existing tests pass, but this is a comprehensive update across the entire repository. The breaking changes in a2a-sdk were discovered during testing and have been addressed, but given the major version jumps in several packages, additional validation in your specific environment is recommended.
