ReleasePort's take
Light signalThe v1.8.58 release adds self‑contained VS Code extension functionality, standalone executables without .NET, automatic agent‑skill registration, Claude Desktop installation support, and per‑skill CLI tools.
Why it matters: Feature additions enable easier deployment (standalone binaries) and skill management; no immediate action required but consider testing new capabilities in dev environments.
