Everything in this new release should be backward compatible.

The only thing which might not, is loading a file and saving it again might change it's layout. Content will be the same, but the order and positions of tensors might be changed to improve the alignment of buffers which can enable much faster loads on lower level languages.

Major changes

• Fixing the fact that the context manager wasn't properly cleaning up after itself. by @Narsil in https://github.com/huggingface/safetensors/pull/166
