Introducing YAMLtecture v0.3.0

Released on February 9, 2026, YAMLtecture v0.3.0 is a stability-focused release that delivers an important user-facing improvement alongside routine maintenance updates. This release ensures version information displays correctly for all installation methods and maintains full backward compatibility with previous versions.

YAMLtecture is a lightweight CLI tool for application architects to generate outputs—including Mermaid diagrams—from YAML-defined system architectures. Version 0.3.0 continues the project’s commitment to reliable, version-controlled infrastructure tooling.

What’s New

Accurate Version Display

The headline improvement in v0.3.0 addresses version reporting for source installations. Running YAMLtecture --version now correctly displays the actual release version (e.g., “v0.3.0”) instead of “dev” when installed via go install. This change improves debugging and support interactions by providing accurate version information in CLI output.

Documentation Updates

The documentation site has been updated with the Just-the-Docs theme v0.12.0, bringing styling improvements and enhancements to the online documentation experience.

Security and Dependency Updates

This release includes important security patches and dependency updates:

  • golang.org/x/term: Updated from 0.37.0 through 0.39.0
  • github.com/go-playground/validator/v10: Updated from 10.28.0 through 10.30.1
  • GitHub Actions workflows updated to latest versions for improved CI/CD reliability

Why It Matters

While v0.3.0 may appear as a maintenance release on the surface, the version display fix addresses a real usability issue for developers who prefer installing tools via go install. Previously, these users had no quick way to confirm which version they were running—now it’s immediate and accurate.

The backward-compatible nature of this release means you can upgrade with confidence. All existing YAML configuration files continue to work exactly as before, making this a safe update for production environments.

For teams relying on YAMLtecture to document and visualize their system architectures, the stability improvements and security updates provide peace of mind while maintaining the familiar workflow you depend on.
