Release Highlights

  • This release contains fixes for the Ray Dashboard. Additional context can be found here: https://www.anyscale.com/blog/update-on-ray-cves-cve-2023-6019-cve-2023-6020-cve-2023-6021-cve-2023-48022-cve-2023-48023 
  • Ray Train has now upgraded support for spot node preemption -- allowing Ray Train to handle preemption node failures differently than application errors.

  • Added gRPC context object into gRPC deployments for user to set custom code and details back to the client.
  • Introduce a runtime environment feature that allows running applications in different containers with different images. This feature is experimental and a new guide can be found in the Serve docs.

💫 Enhancements:

  • Explicitly handle gRPC proxy task cancellation when the client dropped a request to not waste compute resources. 
  • Enable async __del__ in the deployment to execute custom clean up steps.

  • Fixed previously Serve shutdown spamming log files with logs for each event loop to only log once on shutdown.
  • Fixed issue during batch requests when a request is dropped, the batch loop will be killed and not processed any future requests.
  • Updating replica log filenames to only include POSIX-compliant characters (removed the “#” character).
  • Replicas will now be gracefully shut down after being marked unhealthy due to health check failures instead of being force killed.
    • This behavior can be toggled using the environment variable RAY_SERVE_FORCE_STOP_UNHEALTHY_REPLICAS=1, but this is planned to be removed in the near future. If you rely on this behavior, please file an issue on github.

  • Old API stack:
    • APPO/IMPALA: Enable using 2 separate optimizers for policy and vs (and 2 learning rates) on the old API stack. (#40927)
    • Added on_workers_recreated callback to Algorithm, which is triggered after workers have failed and been restarted. (#40354)

💫 Enhancements:

🔨 Fixes:

  • Restoring from a checkpoint from an older wheel (where AlgorithmConfig.rl_module_spec was NOT a “@Property” yet) breaks when trying to load from this checkpoint. (#41157)

Release Highlights

This release features stability improvements and API clean-ups across the Ray libraries.

  • In Ray Serve, we are deprecating the previously experimental DAG API for deployment graphs. Model composition will be supported through deployment handles providing more flexibility and stability. The previously deprecated Ray Serve 1.x APIs have also been removed. We’ve also added a new Java APIs that aligns with the Ray Serve 2.x APIs. More API changes in the release notes below.
  • In RLlib, we’ve moved 24 algorithms into rllib_contrib (still available within RLlib for Ray 2.8).
  • We’ve added support for PyTorch-compatible input files shuffling for Ray Data. This allows users to randomly shuffle input files for better model training accuracy. This release also features new Ray Data datasources for Databricks and BigQuery.
  • On the Ray Dashboard, we’ve added new metrics for Ray Data in the Metrics tab. This allows users to monitor Ray Data workload including real time metrics of cluster memory, CPU, GPU, output data size, etc. See the doc for more details.
  • Ray Core now supports profiling GPU tasks or actors using Nvidia Nsight. See the documentation for instructions.
  • We fixed 2 critical bugs raised by many kuberay / ML library users, including a child process leak issue from Ray worker that leaks the GPU memory (#40182) and an job page excessive loading time issue when Ray HA cluster restarts a head node (#40742)
  • Python 3.7 support is officially deprecated from Ray.

Ray-2.7.0

Release Highlights

Ray 2.7 release brings important stability improvements and enhancements to Ray libraries, with Ray Train and Ray Serve becoming generally available. Ray 2.7 is accompanied with a GA release of KubeRay.

  • Following user feedback, we are rebranding “Ray AI Runtime (AIR)” to “Ray AI Libraries”. Without reducing any of the underlying functionality of the original Ray AI runtime vision as put forth in Ray 2.0, the underlying namespace (ray.air) is consolidated into ray.data, ray.train, and ray.tune. This change reduces the friction for new machine learning (ML) practitioners to quickly understand and leverage Ray for their production machine learning use cases.
  • With this release, Ray Serve and Ray Train’s Pytorch support are becoming Generally Available -- indicating that the core APIs have been marked stable and that both libraries have undergone significant production hardening.
  • In Ray Serve, we are introducing a new backwards-compatible DeploymentHandle API to unify various existing Handle APIs, a high performant gRPC proxy to serve gRPC requests through Ray Serve, along with various stability and usability improvements.
  • In Ray Train, we are consolidating various Pytorch-based trainers into the TorchTrainer, reducing the amount of refactoring work new users needed to scale existing training scripts. We are also introducing a new train.Checkpoint API, which provides a consolidated way of interacting with remote and local storage, along with various stability and usability improvements.
  • In Ray Core, we’ve added initial integrations with TPUs and AWS accelerators, enabling Ray to natively detect these devices and schedule tasks/actors onto them. Ray Core also officially now supports actor task cancellation and has an experimental streaming generator that supports streaming response to the caller.

Take a look at our refreshed documentation and the Ray 2.7 migration guide and let us know your feedback!
