v1.1.1 Breaking: Bedrock runs on aiobotocore BedrockConfig now uses a native async client (aiobotocore) instead of wrapping synchronous boto3 in a thread per call and per streamed event. Every Converse request is also type-checked against the service's own stubs. BedrockConfig(session=...) takes an aiobotocore.session.AioSession. A boto3.Session fails on the first call with AttributeError: 'Sessio…
v1.1.0 TypeSafe Jev support! — decision-only agents AG2 now supports TypeSafe's Jev, a model that doesn't generate text. You send it state and a typed question, and it answers — yes or no, which option, what score — with a probability distribution attached. A decision agent is an ordinary agent, and the response schema you ask for is the question: router = Agent("router", config=TypeSafeConfig(),…

Anthropic SDK 1.x — AG2 adapts to the breaking changes in the Anthropic SDK 1.x line, with Anthropic model name references updated to match. OpenAI SDK 3…
Every MCP surface moves to MCP 2.0, TealTiger governance gains prompt injection detection, ACP hosts can answer a served agent's human-input requests, and human-input failures now surface instead of hanging. MCP 2.0 Breaking change. Every MCP surface has been ported to MCP 2.0, and the dependency bound is now mcp>=2.0.0,<3. If you pin mcp yourself, or depend on a package that pins it below 2.0, yo…
ACP now works in both directions (serve an AG2 agent through ACP), A2A gains signed agent cards and TLS, ElevenLabs joins the realtime voice providers, and the first community extensions land. ACP — serve as well as drive v1.0 could drive CLI coding agents over the Agent Client Protocol. v1.0.2 closes the loop. Serve an AG2 Agent over ACP — Any AG2 Agent can now be exposed as an ACP agent, so ACP…
