JSON All of v2.1.64
EntryKind: in v2.1.64,
ChangesSection of the release

Binary content from MCP tool results is now saved to disk with proper MIME type detection and file extension mapping, rather than being displayed inline. Supports a comprehensive set of MIME types including Office documents, audio, video, and archives.

Evidence

Binary content handling (search for "Binary content (", "application/vnd.openxmlformats")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
