What's Changed

⚡ DeekSeek v3/R1 model support.
⚡ New flexible weight packing: allow quantized weights to be packed to [int32, int16, int8] dtypes. Triton and Torch kernels supports full range of new QuantizeConfig.pack_dtype.
⚡ Over 50% speedup for vl model quantization (Qwen 2.5-VL + Ovis)
⚡ New auto_gc: bool control in quantize() which can reduce quantization time for small model with no chance of oom.
⚡ New GPTQModel.push_to_hub() api for easy quant model upload to HF repo.
⚡ New buffered_fwd: bool control in model.quantize().
🐛 Fixed bits=3 packing and group_size=-1 regression in v1.7.4.
🐛 Fixed Google Colab install requiring two install passes
🐛 Fixed Python 3.10 compatibility
