vLLM package 0.3.0 (upstream vLLM 0.29.0) check your model before this one updates
This release is labelled a minor rather than a patch on purpose: vLLM 0.29 removes ten model architectures and makes Model Runner V2 the default engine. Most installs are unaffected, the package's default model (Qwen/Qwen3-0.6B) and mainstream families like Llama, Qwen, Mistral, DeepSeek and Gemma all continue to work.
But if your LLM_MODEL points at one of the removed architectures, the app will fail to start rather than degrade gracefully:
Arctic, Chameleon, Cheers, Fairseq2Llama, FireRedLID, GritLM, HCXVision, MPT, the RWForCausalLM/StableLMEpochForCausalLM aliases, or PrithviGeoSpatialMAE.
The same applies if you pass the now-removed VLLM_TEST_FORCE_FP8_MARLIN or VLLM_ROCM_USE_AITER_FP4_ASM_GEMM through LLM_EXTRA_ARGS, or rely on the PyAV video decoder backend (use OpenCV or Torchcodec instead).
If you have auto-updates enabled, check the LLM_MODEL value in your app's Environment section now. If it names one of the above, switch to a supported model before the update reaches you. If it has already updated and the app will not start, Cloudron takes a backup immediately before every update, so restoring that backup returns you to the previous version while you pick a replacement model.
