* Python: bump package versions for 1.2.2 release PATCH bump (1.2.1 -> 1.2.2) for the released cohort. Five PRs land in this window: - agent-framework-openai: fix file_search citations breaking the assistant- message history roundtrip (#5557) — drives the released-tier PATCH - agent-framework-orchestrations: [BREAKING] standardize orchestration terminal outputs as AgentResponse (#5301) - agent-framework-core, agent-framework-declarative: preserve Workflow.run() shared state across calls, accept list[Message] in declarative start executor, and coerce Enum values when serializing PowerFx symbols (#5531) - agent-framework-foundry-hosting: add hosted Durable Workflow support (#5531) - agent-framework-azure-contentunderstanding: new alpha package — Azure AI Content Understanding context provider (#4829) - dependencies: workspace package dependency refresh (#5555) Per lockstep convention, all 21 beta packages stamp 1.0.0b260429 and all 4 alpha packages (now including the new contentunderstanding) stamp 1.0.0a260429. Date stamp reflects 2026-04-29 Pacific. Every non-core package floor on agent-framework-core is raised to >=1.2.2; the new contentunderstanding package's stale >=1.0.0 floor is brought into line. Two follow-on fixes bundled to keep validate-dependency-bounds-test green at lowest-direct resolution: - Bump agent-framework-azure-contentunderstanding's azure-ai-content understanding lower bound from >=1.0.0 to >=1.0.1 (1.0.0 ships without proper typing — pyright reports 65 unknown-type errors) - Add pyright ignore comments to core/foundry/__init__.pyi for the new alpha package's type-stub imports, since alpha packages are not in core's [all] extra and therefore aren't installed at lowest-direct * Python: add #5552 to 1.2.2 CHANGELOG Add the streaming-span observability fix to the Fixed section. PR is on upstream/main but not yet pulled into origin/main; the code itself will land via the PR merge. * Python: address PR #5561 review feedback on dependency bounds Two packaging fixes flagged in review: 1. agent-framework-azure-contentunderstanding: add agent-framework-foundry as a runtime dependency. The package's README directs users to `pip install agent-framework-azure-contentunderstanding --pre` and the basic example imports `FoundryChatClient` from `agent_framework.foundry`, so the documented install path was failing with ImportError. Pulling agent-framework-foundry into deps makes the advertised entry path self-contained. 2. agent-framework-foundry: bump agent-framework-openai lower bound from >=1.1.0 to >=1.2.2,<2. Foundry imports private modules from agent_framework_openai (`_chat_client.py:22`, `_agent.py:34`), so resolvers were free to pair foundry==1.2.2 with older OpenAI versions that lack this release's coordinated Responses/history fix. Lockstep the floor with the released cohort to prevent mismatched installs. Both changes pass `validate-dependency-bounds-test` lower + upper at their respective packages.
Agent Framework Lab
This is the experimental package for Microsoft Agent Framework, agent-framework-lab, which contains
various lab modules built on top of the core framework.
Lab modules are not part of the core framework and may experience breaking changes or be deprecated in the future.
What are Lab Modules?
Lab modules are extensions to the core Agent Framework that fall into one of the following categories:
- Incubation of new features that may get incorporated by the core framework.
- Research prototypes built on the core framework.
- Benchmarks and experimentation tools.
Lab Modules
- gaia: Evaluate your agents using the GAIA benchmark for general assistant tasks
- tau2: Evaluate your agents using the TAU2 benchmark for customer support tasks
- lightning: RL training for agents using Agent Lightning

This structure maintains a single PyPI package agent-framework-lab while supporting modular imports through the namespace package mechanism.
Installation
To install each lab module, use the extras syntax with pip:
pip install "agent-framework-lab[gaia]"
pip install "agent-framework-lab[tau2]"
pip install "agent-framework-lab[lightning]"
Usage
Import and use lab modules from the agent_framework.lab namespace.
For example, to use the GAIA module:
# Using GAIA module
from agent_framework.lab.gaia import GAIA
Running Tests Locally
For machine-safe local runs, prefer package-scoped commands first:
uv run --directory packages/lab poe test
uv run --directory packages/lab pytest -q -m "not integration"
When you need to run lab tests from the repository root, scope the root task to the lab package:
uv run poe test -P lab
Lightning observability tests intentionally exercise heavier tracing paths and are marked as resource_intensive:
uv run --directory packages/lab pytest lightning/tests/test_lightning.py -m "resource_intensive" -q
Should I consume Lab Modules?
If you are looking for stable and production-ready features, you should not use lab modules. Stick to the core framework.
If you are looking for experimentation, research, or want to benchmark different approaches -- most importantly, if you don't mind breaking changes and potential deprecations -- then lab modules are for you.
Contributing to Lab Modules
Microsoft-maintained modules
For Microsoft-maintained modules in this repository, please follow standard contribution guidelines and submit pull requests directly to this repository.
Community modules
If you want to contribute a community-maintained lab module:
- Create a new repository on GitHub for your module
- Tag your repository with
agent-framework-labfor discoverability - Submit a PR to add a link to your repository in the Lab Modules section above
- Use the PR title format:
[New Lab Module] Your Module Name
We will review your submission based on the guidelines below.
Guidelines
- Purpose: Community modules should fit into one of the three categories of lab modules (incubation, research, benchmarks)
- Namespace: Community modules should avoid the
agent_framework.labnamespace (reserved for modules maintained in this repository) - Dependencies: Minimize external dependencies, always include
agent-frameworkas a base dependency - Documentation: Include comprehensive README with installation instructions and usage examples
- Tests: Write comprehensive tests with good coverage
- Type hints: Always include type hints and a
py.typedfile - Versioning: Use semantic versioning, start with
0.1.0for initial releases
