# Announcing Serverless Workflow SDK Go 3.0.0

We are thrilled to announce the release of **Serverless Workflow SDK Go 3.0.0**, a milestone that aligns with the latest Serverless Workflow specification (v1.0.0).

## **What’s New in 3.0.0?**

This release introduces a host of new features and improvements:

1. **Support for Serverless Workflow Specification 1.0.0**
The SDK now fully supports the latest workflow specification, ensuring compatibility with modern standards and enabling developers to leverage advanced features effortlessly.

2. **Improved DSL Parsing**
The new implementation of the DSL parser ensures more robust validation and parsing of workflow definitions, adhering strictly to the updated JSON Schema.

3. **Reusable Components**
The introduction of reusable components such as authentication policies, error handlers, and catalogs simplifies workflow definitions and promotes consistency across workflows.

4. **Schema Validation and Interoperability**
With Go validators integrated natively, developers can rely on robust schema validation for input, output, and context management, ensuring workflows are reliable and error-free.

5. **Developer-Focused Improvements**
- Enhanced Go language idioms for better developer experience.
- Improved code organization for scalability and maintainability.

## **Getting Started**

Upgrading to the new version is straightforward:

1. Update your project to use the new `v3` path:
```bash
go get github.com/serverlessworkflow/sdk-go/v3
```

2. Update your code to accommodate the new DSL and schema changes. Refer to the updated [specification](https://github.com/serverlessworkflow/specification/tree/main/examples) for examples.

3. Run your tests and validate your workflows against the new schema to ensure a smooth transition.
