wayflow-26.1.0

We are excited to announce WayFlow 26.1.0!

This release delivers brings functionalities to easily deploy agents to production, improvements to multi-agent patterns, easier extensibility and safer template rendering.

You can install it from Pypi with:
pip install "wayflowcore==26.1.0"

What's new:

Server deployment & integrations

• Run your agents as a server: New built-in server makes it easy to deploy, run, and integrate your agents in production environments.
• OpenAI Responses API and A2A supported: Effortlessly connect WayFlow with OpenAI’s latest response APIs and agent-to-agent (A2A) workflows.

Multi-agent patterns improvements

• Refined Swarm coordination: Improved Swarm prompts and added HandoffMode to better guide delegation and enforce handoff behavior when required.
• More powerful multi-agent composition: Swarm and ManagerWorkers now support multiple tool calls per turn, and you can now build hierarchical ManagerWorkers and integrate Swarm/ManagerWorkers directly into Flows.

Security and compliance

• Stricter Jinja template rendering: No access to object attributes, only safe dictionary and loop properties. Templates that previously worked may now raise security errors.

Extensibility

• WayFlow Plugins: Extend or create Tools, Steps, and seamlessly integrate custom components in serialization and deserialization.

Breaking changes

• Stricter environment for Jinja templates rendering
• Deprecated methods and parameters removed:
• Use conversation.execute() instead of deprecated Agent/Flow.execute().
• Replace ChatHistoryContextProvider with FlowContextProvider using GetChatHistoryStep.
• Use begin_step (passing a Step) instead of begin_step_name.
• Tool names: Now enforce valid names, no whitespaces or special characters a deprecation warning is raised; in the next cycle, an error will be thrown.

Bug fixes & quality

• Default input values for agents now respected.
• Internal sanitization of agent and flow names prevents LLM API errors for multi-agent workflows.

wayflow-25.4.3

Stricter environment for jinja templates rendering

We now use a stricter version of the SandboxedEnvironment for rendering jinja templates. No access to object attributes is allowed, only key-based access to python dictionaries and main jinja LoopContext properties are allowed.
