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.
• Ray is now compatible with Pydantic versions <2.0.0 and >=2.5.0, addressing a piece of user feedback we’ve consistently received.
• The Ray Dashboard now has a page for Ray Data to monitor real-time execution metrics.
• Streaming generator is now officially a public API (#​41436, #​38784). Streaming generator allows writing streaming applications easily on top of Ray via Python generator API and has been used for Ray Serve and Ray data for several releases. See the documentation for details. 
• We’ve added experimental support for new accelerators: Intel GPU (#​38553), Intel Gaudi Accelerators (#​40561), and Huawei Ascend NPU (#​41256).

Ray Serve

🎉 New Features:

• Introduce logging config so that users can set different logging parameters for different applications & deployments.
• 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.
• Make Ray Serve compatible with Pydantic versions <2.0.0 and >=2.5.0.

🔨 Fixes:

• Fixed gRPC proxy streaming request latency metrics to include the entire lifecycle of the request, including the time to consume the generator.
• Fixed gRPC proxy timeout request status from CANCELLED to DEADLINE_EXCEEDED.
• 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.
