- **Breaking:** Upgrade to `agent-client-protocol` 2.x. Transport implementations and the core
handlers/types they connect must be migrated together.
- **Fixed:** Preserve incoming JSON-RPC batch frames and grouped responses across HTTP and WebSocket
transports, including session-aware HTTP routing.
transports, including session-aware HTTP routing. HTTP clients now validate and track every batch
entry and open streams returned by grouped `session/new` and `session/fork` responses.
- **Fixed:** Establish connection and session SSE streams before posting dependent messages while
continuing to deliver callbacks and complete earlier POSTs during setup. Pending setup is
cancelled cleanly when the caller exits.
- **Fixed:** Keep call-bearing and invalid-request batch POSTs in peer order while allowing
response-only frames, including malformed response-shaped values, to bypass a
pending request when completing an SSE callback.
- **Fixed:** Allow an initial HTTP batch whose first call-shaped entry is `initialize`
to create a connection and return its success or rejection as one grouped
JSON-RPC response, ignoring any leading response-only entries and buffering
sibling side traffic for the connection stream until initialization completes.
- **Fixed:** Drain final routed messages to established HTTP SSE and WebSocket streams before
closing them when the connected agent exits.
