• New model: JetBrains' Mellum v2, an open-weights Mixture-of-Experts code-generation model (#43992).1
• Fix HyperCLOVAX loading after the upstream HuggingFace repo removed its remote code (now native in transformers >= 5.9.0): register the hyperclovax modeltype so vLLM uses its vendored config instead of the stale automap (#43860).1
