Introduction

We’re pleased to announce the release of mcp-acronym-lookup v0.2.1, published on November 29, 2025. This maintenance release delivers important underlying updates that keep your acronym lookup server running smoothly with the latest security patches and performance improvements from the Go runtime and MCP framework.

What’s New

While v0.2.1 doesn’t introduce new features, it brings valuable behind-the-scenes enhancements:

  • Updated Go Runtime: Upgraded to Go 1.25.4 for improved performance and security
  • MCP Framework Updates: Bumped the underlying mcp-go library from v0.37.0 to v0.43.1, incorporating upstream improvements and bug fixes
  • Enhanced Build Provenance: Updated GitHub Actions workflows with improved artifact attestation for better supply chain security

Why It Matters

This release demonstrates our commitment to active maintenance and security. By keeping dependencies current, we ensure:

  • Security: Regular updates to the Go runtime and framework protect against known vulnerabilities
  • Compatibility: Staying current with the MCP specification ensures continued interoperability with AI agents and tools
  • Reliability: Updated CI/CD infrastructure means more consistent builds and releases

Most importantly, this release is fully backward compatible. If you’re currently running v0.2.0, your existing deployment will work identically—no configuration changes or breaking updates to worry about.
