Announcing ADK-Rust v0.1.8: Visual Agent Builder & Rust 2024

1. ADK Studio: Visual Agent Builder

We are thrilled to introduce ADK Studio, a powerful visual environment for designing, testing, and deploying AI agents. With ADK Studio, you can:

• Visual Workflow Editor: Drag and drop agents, tools, and routers to create complex workflows without writing boilerplate code.
• Real-time Testing: Chat with your agents immediately as you build them, with live state inspection.
• Code Generation: Export your visual designs to production-ready Rust code with a single click.

2. Rust 2024 Edition Support

ADK-Rust v0.1.8 fully supports the new Rust 2024 edition. We've updated our internal crates to leverage the latest language features, ensuring better performance and ergonomics.

[package]
edition = "2024"
rust-version = "1.85"

[dependencies]
adk-rust = "0.1.8"

3. New Router Agent

The new Router Agent pattern simplifies intelligent request routing. Instead of complex prompt engineering, use the dedicated Router Agent to dispatch tasks to specialized sub-agents based on intent.

let router = LlmAgentBuilder::new("router")
    .description("Routes requests to the appropriate specialist")
    .sub_agents(vec![
        Arc::new(billing_agent),
        Arc::new(tech_support),
        Arc::new(sales_agent),
    ])
    .model(Arc::new(model))
    .build()?;

4. Breaking Changes

This release includes a few breaking changes to improve consistency and stability:

• Renamed `gemini_rust` crate to `adk_gemini` for consistency.
• Updated minimum supported Rust version to 1.85.
• Refactored `AgentBuilder` to `LlmAgentBuilder` for clarity.
