v1.0.0b0

🎉 AG2 v1.0.0b0 - The First Beta of v1.0

We've reached a major milestone and are one step closer to v1.0: v1.0.0b0 is the first beta of AG2 v1.0. The new framework we've been building as an agentic platform for production use. The classic framework (autogen.x / ConversableAgent) has now been removed from this repository.

A big thanks to everyone who has been involved with building this new framework.

AG2 Classic Has Moved (autogen / ConversableAgent)

The AG2 Classic framework — everything you know as ConversableAgent, GroupChat, initiate_chat, and the surrounding tooling — now lives at its own repository: ag2ai/ag2-classic. It continues to be maintained in maintenance mode (security and critical bug fixes).

What to Install

Install command	What you get	Repo
pip install ag2	The new AG2 — actively developed (this release: v1.0.0b0)	ag2ai/ag2
pip install autogen	AG2 Classic (ConversableAgent, GroupChat, …) — maintenance mode	ag2ai/ag2-classic

If you build with ConversableAgent and want to stay on AG2 Classic, use pip install autogen. The import path stays import autogen — nothing changes for your existing code.

If you're moving to the new AG2, the top-level package is now imported as ag2 (the autogen import name is no longer available in this repo). Install with pip install ag2 and import with import ag2.

Beta Promoted to Mainline

This is the foundational change of the v1.0 series:

• autogen.beta promoted to the top level ag2.x – The framework built up under autogen.beta across v0.12 → v0.14 is now the mainline framework in this repo.
• Classic framework removed – The classic agents, orchestration surfaces, and interoperability layers that were deprecated in v0.12.0 and removed from this repo in v0.14.0 are now fully absent. Classic users should migrate to ag2ai/ag2-classic.
• Classic CLI removed – The classic command-line entry point is gone with the classic framework.

🌐 New Features

🔗 NLIP Integration

• NLIP support – First-class integration for the Natural Language Interaction Protocol.

💻 ACP — Drive CLI Coding Agents

• ACP support – First-class support for driving external CLI coding agents (Claude Code, Codex, OpenCode, Gemini CLI, and others) as Agents over Agent Client Protocol (ACP)!

🔍 Server-Side Tool Search + Deferred Loading

• Server-side tool search – New tool discovery mechanism with deferred tool loading, so agents can find and load tools on demand rather than upfront.

📁 Z.AI Files API

• Z.AI Files API – File API support added to the Z.AI (GLM) provider.

🔧 Fixes & Improvements

• 🧪 UsageEvent excluded from history compaction – UsageEvent telemetry is now excluded from history compaction via the __conversational__ marker.
• 📏 History sizing – History is now sized correctly for effective compaction with the agent harness.
• 🔴 Redis listener cancellation – Redis listener cancellation is now propagated correctly.
• 🔢 __version__ at top level – __version__ is now exported at the top level of the package.
• 📦 NLIP dependency – Require nlip-server >= 0.1.3 to drop the transitive fastapi < 0.116 pin.
• 📦 Extras resolution – Align protobuf and typer pins so uv resolves all extras.

---

🏗️ CI & Maintenance

• Documentation builds only on manual dispatch or published release.
• One combined coverage report per run instead of per matrix job.
• Dependency bumps: uv group (23 updates), github-actions group (2 + Anthropic Claude Code Action).
