We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Flax actually requires jax 0.3.2
https://github.com/google/flax/blob/ef6bf4054c30271a58bfabb58f3d0049ef5d851a/flax/linen/initializers.py#L19

the constant initialiser was added in this commit https://github.com/google/jax/commit/86e8928e709ac07cc51c10e815db6284507c320e that was first included in jax 0.3.2

This came up in NetKet's automated oldest-version-dependencies testing.
