Bumps ray from 2.47.0 to 2.52.0.

Release notes

Sourced from ray's releases.

Ray-2.52.0

Release Highlights

Ray Core:

  • End of Life for Python 3.9 Support: Ray will no longer be releasing Python 3.9 wheels from now on.
  • Token authentication: Ray now supports built-in token authentication across all components including the dashboard, CLI, API clients, and internal services. This provides an additional layer of security for production deployments to reduce the risk of unauthorized code execution. Token authentication is initially off by default. For more information, see: https://docs.ray.io/en/latest/ray-security/token-auth.html

Ray Data:

  • We’ve added a number of improvements for Iceberg, including upserts, predicate and projection pushdown, and overwrite.
  • We’ve added significant improvements to our expressions framework, including temporal, list, tensor, and struct datatype expressions.

Bug: Duplicate pydantic dependency in train extra

The train extra for Ray 2.52.0 lists pydantic (<2.0.dev0 || >=2.5.dev0,<3) twice in the dependency array. This duplicate entry is redundant and likely indicates an error in the Ray package metadata that was carried over into the lock file during the version bump.
