v0.14.0

Highlights

🛣️ Path to v1.0 — Deprecations Removed

v0.14.0 is a milestone release on the path to v1.0. The deprecations announced in v0.12.0 have now been removed from the Classic framework (autogen). This brings us very close to v1.0, where the Beta framework (autogen.beta) will become the new AG2.

📍 Release Roadmap

---

⚠️ Preparing for v1.0 — pip install autogen vs pip install ag2

At v1.0, the package names will reflect AG2's transition. If you build with ConversableAgent today, this matters to you:

Install command	What you get
pip install autogen	AG2 Classic — the current ConversableAgent-based framework
pip install ag2	The new AG2 — the framework that is currently in Beta (autogen.beta)

If you want to stay on AG2 Classic past v1.0, use pip install autogen. At v1.0, the Classic codebase will move to its own branch or repo, while pip install ag2 will install the new framework that today lives under autogen.beta.

🔬 Beta Framework

🖥️ A2UI

• 🖥️ A2UI – A2UI joins the beta framework! Beta agents can now generate UI on the fly. Docs

🤖 Observable Agent.run / AgentReply.run

• 👁️ Observable run surface – New Agent.run and AgentReply.run methods sit alongside ask, returning an observable handle so callers can step through and/or watch the run as it unfolds. Docs

🧠 Agent Resume

• 🔁 Agent Resume – Resume an agent's execution from an intermediate state, rather than just a turn. Allows fine-grained replays and forking. Docs

⚡ New LLM Provider

• ⚡ Z.AI (GLM) – Added support for Z.AI / GLM models, including GLM 5.2.

🎨 Gemini: Image Generation & Editing

• 🖼️ Gemini Image Generation, Editing & image_config – The Beta Gemini config now supports image generation, editing, and a dedicated image_config for fine-tuned image behavior. Docs

🧰 Skills

• 🏗️ Multi-Runtime Composition + MemorySkill – Skills can now compose across runtimes; new MemorySkill provides code-defined skills.

🌐 Network

• 🏷️ Hub.register(agent) Convenience – New convenience method with per-agent client lifecycle.
• 🔧 Fail Fast on Self-Delegation – Network now fails fast when a delegate targets itself.

🔧 Beta Fixes & Improvements

• 🔁 Compaction Preserves Tool Cycles – Compaction now keeps tool-call cycles intact and renders CompactionSummary correctly.
• 🧱 Zero-Argument Tools JSON Schema – Emit a valid empty-object JSON Schema for zero-argument tools.
• 🔧 Falsy Non-Field Event Defaults – Preserve falsy non-Field defaults on events.
• 🔧 Gemini Multi-Part Text – Concatenate multi-part text in non-streaming response.
• 🔧 OpenAI Completions Mapper – Dropped unreachable FileIdInput branch.
