- Support for 32 and 8-bit Lion has been added. Thank you @lucidrains
- Support for serialization of Linear8bitLt layers (LLM.int8()). This allows to store and load 8-bit weights directly from the HuggingFace Hub. Thank you @myrab
- New bug report features `python -m bitsandbytes` now gives extensive debugging details to debug CUDA setup failures.
Bug fixes:
- Fixed a bug where some bitsandbytes methods failed in a model-parallel setup on multiple GPUs. Thank you @tonylins
- Fixed a bug where cudart.so libraries could not be found in newer PyTorch releases.
Improvements:
- Improved the CUDA Setup procedure by doing a more extensive search for CUDA libraries
Deprecated:
- Devices with compute capability 3.0 (GTX 700s, K10) and 3.2 (Tegra K1, Jetson TK1) are now deprecated and support will be removed in 0.39.0.
- Support for CUDA 10.0 and 10.2 will be removed in bitsandbytes 0.39.0
