ExcelMcp 1.8.64 expands distribution flexibility with self-contained VS Code extension, standalone executables, and Claude Desktop packages—all eliminating .NET runtime requirements. NuGet installation remains the exception, still requiring .NET 10.

Why it matters: ExcelMcp now offers .NET-free installation paths (VS Code extension, standalone executables, Claude Desktop). NuGet users must have .NET 10. Evaluate distribution method for your deployment; no action required for existing installs.
