v11.7.0

Headline

• A new POST /v1/models/register endpoint registers or updates user.* model definitions without downloading any files.
• New GET/POST/DELETE /v1/models/{id}/options endpoints save, inspect, and reset per-model recipe options without loading the model, with per-load transient overrides.
• New GET /v1/stats and Prometheus /metrics endpoints report prefix-cache effectiveness and router route-switch counters.
• The built-in catalog adds the Qwen3.8-27B and NVIDIA Nemotron 3.5 Lightning 30B-A3B GGUF models and the Z-Image-Turbo image model.
• Lemonade can now be installed on Windows with winget and on macOS with a Homebrew cask.

Breaking Changes

• POST /pull now returns 400 and registers nothing when a model definition names an unservable or contradictory deployment mode; such labels are no longer silently normalized.
• Stored user_models.json entries that violate the new deployment-mode label rule are now skipped at startup with an error instead of being repaired.
• Removed the deprecated Lite Collection and Ultra Collection model registry entries.
• /v1/audio/transcriptions now returns raw text bodies for text/srt/vtt instead of a JSON {text: ...} wrapper, and returns 400 for unsupported response_format values.
• The TheNoise image backend no longer accepts per-request upscale and lora_dir recipe options; lora_dir is now set server-wide in config.json and upscale is only honored as a passed-through request parameter.
• lemonade launch opencode now emits a limit object (limit.context/limit.output) instead of a top-level contextWindow field.
• The no_broadcast config key is replaced by an inverted broadcast boolean, auto-migrated on load.
• An existing but unreadable extra_models_dir now returns 400 on /internal/set instead of being silently applied.
