Introducing YAMLtecture v0.2.1

We’re excited to announce the release of YAMLtecture v0.2.1, published on October 21, 2025. This release brings official version support to the CLI and continues our commitment to security and infrastructure stability.

YAMLtecture is a lightweight Go-based CLI tool that helps architects generate Mermaid diagrams and other outputs from YAML-defined system architectures. Version 0.2.1 focuses on maturing the project’s infrastructure while adding essential user-facing capabilities.

What’s New

Version Support

The most significant addition in v0.2.1 is official version support for the CLI. You can now verify your installation with a simple command:

YAMLtecture --version

This feature addresses a common need among users who want to confirm which version they have installed and ensure compatibility with documentation or support requests. The version information is injected at build time during release workflows, ensuring accuracy across all distributed binaries.

Enhanced Security Verification

This release introduces build provenance attestations through GitHub Actions. When you download pre-compiled binaries from the release page, you now have access to cryptographic verification that confirms the artifact’s origin and build process—a critical addition for enterprise environments with strict supply chain security requirements.

Why It Matters

While v0.2.1 may appear as a maintenance release, it represents important maturation of the YAMLtecture project. The ability to check versions is fundamental infrastructure that every CLI tool needs, and its addition signals the project’s growing maturity.

The six-and-a-half-month development period between v0.2.0 and v0.2.1 focused heavily on:

  • Security hygiene: Regular updates to the Go runtime (through version 1.25.3) and dependencies ensure your installations benefit from the latest security patches
  • Test coverage: New test cases for complex query operations with ‘and’/’or’ conditions strengthen the reliability of link filtering features
  • Platform support: Pre-compiled binaries are available for seven platform and architecture combinations across Linux, macOS, and Windows

This commitment to infrastructure quality means users can trust YAMLtecture as a stable tool for their architectural documentation workflows.

Getting Started

Installation Options

Binary Download (Recommended) Visit the v0.2.1 release page to download pre-compiled binaries for your platform. Each archive includes checksum files for verification:

  • Linux: amd64, 386, arm64
  • macOS: amd64, arm64 (Apple Silicon)
  • Windows: amd64, 386

Go Installation If you have Go installed, you can install directly from the source:

go install github.com/UnitVectorY-Labs/YAMLtecture@v0.2.1

Upgrade Notes

Upgrading from v0.2.0 is seamless—there are no breaking changes in this release. The new --version flag is purely additive and doesn’t affect existing functionality.

Looking Forward

Version 0.2.1 lays important groundwork for future development. With version tracking in place and security infrastructure matured, the project is well-positioned for continued feature development while maintaining the reliability that architects depend on for their documentation workflows.

We appreciate the community’s engagement with YAMLtecture. Whether you’re using it to visualize microservices architectures, document cloud infrastructure, or create system diagrams for technical specifications, your feedback drives our priorities.
