v2.3.22

# Changelog

## New features

- **Agent Skills**: Introducing the `Skills` class, enabling you to extend your Agents’ capabilities by providing specific skills, as defined by Anthropic’s [Agent Skill specification](https://agentskills.io/home). See the [docs](https://docs.agno.com/basics/skills).
- **Dynamic headers for MCP**: You can now pass a `header_provider` function to your MCPTools instances to generate dynamic headers when calling MCP tools. This is useful for headers that need to change based on context e.g. authorization tokens or user ids. See the [docs](https://docs.agno.com/basics/tools/mcp/dynamic-headers).

## Improvements:

- **Reasoning models**: enable native reasoning for the following reasoning models:
    - OpenAI GPT-5.1 and 5.2 models
    - New Gemini 3, 3.5 and deepthink model
    - New DeepSeek r1 and reasoner models.
- **JWT Middleware Audience**: Allow setting of the expected `audience` for checking
- **MCP transport default**: The `MCPTools` class now defaults to `StreamableHttp` as transport when connecting to external MCP servers.
- **Postgres DB**: Updates to the database session pooling logic and handling of illegal characters in any strings to store.0
- **A2A Remote Agents**: Added support for `a2a` protocol when using remote agents. The also means Google ADK agents can be used with AgentOS as remote running agents. This feature is still in beta. See the [docs](https://docs.agno.com/agent-os/remote-execution/overview).

## Bug Fixes:

- **Chunking:** Fixed paragraph and newline splitting in chunking strategies.
- **Early Termination in Workflows:** Propagate `stop` flag from primitive inner steps to workflow
- **Context compression for OpenAIResponses**: Update our `CompressionManager` to work properly with any model using the `OpenAIResponses` API.
