ReleasePort's take

Light signal

editorial:auto 13d

The v1.8.61 release bundles the MCP Server and CLI within the VS Code extension, offers standalone executables without .NET runtime, and requires .NET 10 only for NuGet‑based tool installation.

Why it matters: If you use the VS Code extension or standalone packages, note that no .NET runtime is needed; upgrade to v1.8.61 now. Only projects installing via NuGet must have .NET 10 available.
