# What's New in 0.1

Use the first RubyLLM AG-UI release to stream, resume, cancel, and reconnect agent runs.

After reading this guide, you will know:

* How to install version 0.1.
* Which run lifecycle features it provides.
* Which compatibility checks still need a real application.

## Install the First Release

```ruby
gem 'ruby_llm-ag_ui', '~> 0.1.0'
```

Use Ruby 3.2 or later, RubyLLM 2.1 or later within version 2, and `ag-ui-protocol` 0.2. Follow [Getting Started](/next/getting-started/) to create your first run.

## Stream One Chat Turn as One Run

The gem validates `RunAgentInput` and maps RubyLLM text, tool, and lifecycle callbacks to AG-UI events. An SSE writer sends each encoded event to the client. See [Streaming Runs](/next/streaming-runs/) and [Protocol Coverage](/next/protocol-coverage/).

## Pause, Resume, Cancel, and Reconnect

Tool approval pauses use interrupts bound to their tool calls. Your host authorizes the actor and records the decision before resuming. Cancellation produces the cancelled outcome. A retry for a completed run replays its recorded state and terminal event. See [Approval and Resume](/next/approval-and-resume/) and [Reconnects](/next/reconnects/).

## Add the Optional Rails Adapter

The adapter supplies a streaming controller concern, an ActiveRecord run store, and an installation generator. The pure-Ruby entrypoint does not load Rails. Follow [Rails Integration](/next/rails-integration/).

## Check Your Application's Compatibility

Offline checks cover the mapping, schema, lifecycle, store, and adapter behavior. A release does not establish interoperability with every AG-UI client or live provider. Read [Compatibility](/next/compatibility/) and record your application checks before making those claims.
