Headline

  • The Lemonade Router is complete: name a collection.router model and requests are steered by rule, classifier, semantic-similarity, or LLM-as-router policies, with per-candidate decision traces, a GUI for authoring and editing routers, and a POST /v1/classify text-classification endpoint backed by a new onnxruntime backend.
  • ModelScope is now searchable alongside Hugging Face in the Model Manager, with source-aware model discovery, download, and registration.
  • A server-side job engine lets clients post multi-step recipes and manage them through /jobs endpoints, with pause, interrupt, resume, and delete lifecycle control.
  • lemond can act as an MCP client host, connecting to external stdio MCP servers and discovering their tools through admin-gated /internal/mcp/* endpoints.
  • The lemonade CLI now supports HTTPS/TLS connections to secure remote endpoints, honoring http(s):// schemes in LEMONADE_HOST.

Breaking Changes

  • The server no longer sends Access-Control-Allow-Origin: * by default: non-loopback browser origins are now rejected with 403 unless listed in LEMONADE_ALLOWED_ORIGINS, and the WebSocket same-origin fallback has been removed. Remote or LAN browser clients must set LEMONADE_ALLOWED_ORIGINS.
