v11.6.0

Headline

• The Muse-Glimmer-30B-GGUF model joins the built-in llama.cpp catalog with draft decoding, vision, and tool-calling support.
• The llama.cpp ROCm backend now runs on AMD Instinct MI100, MI200, MI210, and MI250 GPUs on Linux.
• A new experimental TheNoise ROCm image-generation backend brings Anima and Krea-2 to AMD Strix Halo and Strix Point iGPUs.
• The new lemonade alias commands let you assign your own names to models, with alias-aware /v1/models listing and admin endpoints.
• lemonade bench adds opt-in vision benchmark scenarios for multimodal models.

Breaking Changes

• /v1/audio/speech with stream_format=audio and a non-PCM response_format (such as mp3) against Kokoro now returns HTTP 400 (only pcm is supported) instead of silently returning PCM audio.
• /v1/models now lists each GGUF quant in a split extra_models_dir subfolder as its own entry rather than one entry per folder; the old folder name still resolves as a hidden request alias.
• The Windows MSI layout changed: Lemonade_Server_MSI now contains only lemonade-server-minimal.msi, and the desktop lemonade.msi now ships in a new Lemonade_Desktop_MSI artifact, so automation that reads lemonade.msi from the old artifact must be repointed.
