v1.86.7 is a patch release on top of v1.86.6. It backports cost-tracking recovery for interrupted Anthropic streams, adds a no-mcp-servers sentinel that scopes a key to zero MCP servers, caps Anthropic cache_control injection at the 4-block API limit, and bumps OpenSSL plus cryptography, python-multipart, pydantic-settings, and pypdf for CVE coverage.
