Release notes

Sourced from chex's releases.

Chex 0.1.82

What's Changed

Chex has moved from external dm-tree to the JAX-native jax.tree_util library for operating with PyTrees. This means that Nones will not be treated as separate leaves by chex tree assertions any longer. Note that you can still check for Nones using chex.assert_tree_no_nones().

• Remove usage of dm-tree in asserts. by @​copybara-service in deepmind/chex#288
• Add support for kw_only for chex.dataclass. by @​jblespiau in deepmind/chex#290
• Deprecate ignore_nones. by @​copybara-service in deepmind/chex#292

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.
