Released on May 23, 2026, YAMLtecture v0.3.1 is a maintenance and documentation-focused update designed to help you get the most out of your architecture-as-code workflow. This release bridges the gap between tool capabilities and practical application, ensuring that architects can quickly move from a blank YAML file to a professional Mermaid diagram.

What’s new

The highlight of this release is a significant expansion of the official documentation. We have introduced a comprehensive Examples section that provides five test-validated use cases, giving you a blueprint for various architectural patterns:

  • Microservices Architecture: Learn how to map API gateways and interconnected services.
  • Cloud Infrastructure: Explore hierarchical layouts using parent-child relationships and Mermaid subgraphs.
  • Data Pipelines: See how to model ingestion-to-dashboard flows and use query filtering to focus on specific architectural subsets.
  • Multi-File Configuration: Discover how to keep your projects organized by splitting definitions across multiple YAML files.
  • Styled Mermaid Diagrams: Get tips on customizing your output with node and link styles for better visual communication.

Additionally, we’ve improved the CLI experience. Running the --version flag now provides detailed environment metadata, including the Go compiler version and your operating system/architecture, making it easier to verify your installation and troubleshoot environment-specific issues.

Why it matters

For many users, the hardest part of adopting a new tool is knowing exactly how to structure the input to achieve a specific result. By providing these validated examples, we’re lowering the barrier to entry and providing a library of patterns that you can copy, paste, and adapt for your own systems.

Behind the scenes, this release also brings critical stability and security updates. We’ve bumped several key dependencies and updated the project to target Go v1.26.3, ensuring that YAMLtecture remains performant and secure as it grows.

Getting started with v0.3.1

Updating to the latest version is straightforward. You can download the pre-compiled binaries from the GitHub Releases page, or if you have Go installed, simply run:

go install github.com/UnitVectorY-Labs/YAMLtecture@latest

Whether you are documenting a simple internal tool or a complex cloud-native ecosystem, YAMLtecture v0.3.1 provides the guidance and stability needed to make your architectural visions a reality.
