We introduced conventional A2A endpoints — including Agent Card retrieval — and aligned run endpoints and payloads to the updated protocol. This reduces custom handling across clients, improves cross-system compatibility, and clarifies long-term API boundaries.

Details:

- New Agent Card retrieval endpoint
- Protocol-aligned run endpoints and payloads
- Requires client updates to adopt the new endpoints and schema

Who this is for: Platform teams integrating agents across services and organizations standardizing on A2A interfaces.
