* Python: bump package versions for 1.2.1 release PATCH bump (1.2.0 -> 1.2.1) for the released cohort. The release window covers two PRs, no new public APIs: - agent-framework-core: prevent inner_exception from being lost in AgentFrameworkException (#5167) - samples: add requirements.txt and .env.example to the a2a/ hosting sample for pip-based setup (#5510) Per lockstep convention, all 21 beta packages stamp 1.0.0b260428 and all 3 alpha packages stamp 1.0.0a260428, regardless of per-package code churn. Every non-core package floor on agent-framework-core is raised to >=1.2.1 to keep cohort signaling consistent. Date stamp reflects the local (Asia) cut date 2026-04-28. * Python: silence pyright unknown-type warnings in hosted-env detection `azure.ai.agentserver.core` is probed at runtime via `importlib.util.find_spec` and is not a declared dependency. The existing `# pyright: ignore[reportMissingImports]` suppresses the missing-import warning, but at `lowest-direct` resolution pyright still reports the imported symbol (`AgentConfig`) and its members (`from_env`, `is_hosted`) as unknown, breaking `validate-dependency-bounds-test` for `packages/core`. Extend the existing ignore to cover `reportUnknownVariableType` on the import and `reportUnknownMemberType` on the call site so the bounds check returns to green. Behavior is unchanged. Latent since #5455 (shipped in 1.2.0). * Python: raise agent-framework-gemini lower bound to google-genai>=1.65.0 The Gemini chat client references several `google.genai.types` symbols (`FileSearch`, `ThinkingLevel`, `SearchTypes`, `McpServer`, `StreamableHttpTransport`, plus call-site keyword args `mcp_servers` and `search_types`) that are not present at the lower bound of `google-genai>=1.0.0`. At `lowest-direct` resolution this caused `validate-dependency-bounds-test` to fail for `packages/gemini` with eleven `reportAttributeAccessIssue` / `reportUnknownVariableType` errors. Walking the upstream `google.genai.types` API: - `GoogleMaps`, `AuthConfig`: present from 1.40.0 - `FileSearch`: introduced in 1.49.0 - `ThinkingLevel`: introduced in 1.55.0 - `SearchTypes`, `McpServer`, `StreamableHttpTransport`: introduced in 1.65.0 Bump the lower bound to 1.65.0 — the minimum version that exposes every symbol the package actually uses. Keep the `<2.0.0` upper cap unchanged. With this bump `validate-dependency-bounds-test` passes for both lower and upper resolution scenarios across all 27 workspace packages. Latent since #4847 (Gemini package introduction in 1.1.0); aggravated by subsequent feature additions that pulled in newer `types.*` symbols. * Python: add dependabot bumps to 1.2.1 CHANGELOG Catalog the 15 dependabot dependency updates that merged on `upstream/main` between python-1.2.0 and the 1.2.1 cut window under a new Changed section: - Workspace dev/runtime deps: `rich`, `prek`, `python-multipart`, `pyasn1`, `pytest` (ag-ui, devui, lab), `uv` (lab) - Frontend deps: `vite` (devui, chatkit), `postcss` (devui, chatkit, handoff), `picomatch` (devui, handoff) CHANGELOG-only — no source or pyproject.toml changes. PRs themselves merged upstream independently of this release branch and will be brought in via the PR merge.
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
