Looks like 2.12 pulls in both jax and ml-dtypes which is curious. Also noting that there is no licence change for alibi-detect (meaning those two were already pulled in previously?).

I think jax uses ml-dtypes, and I know tf 2.7 added this "Add experimental API experimental_from_jax to support conversion from Jax models to TensorFlow Lite", but confused why the jax licence is only being added now...

Edit: Apache 2.0 licence is OK though isn't it?
