Ray-2.6.1

The Ray 2.6.1 patch release contains a critical fix for cluster launcher, and compatibility update for Ray Serve protobuf definition with python 3.11, as well doc improvements.

⚠️ Cluster launcher in Ray 2.6.0 fails to start multi-node clusters. Please update to 2.6.1 if you plan to use 2.6.0 cluster launcher.

Ray Core

• [serve] Cherry-pick Serve enum to_proto fixes for Python 3.11 #37660

Ray-2.6.0

Release Highlights

• Serve: Better streaming support -- In this release, Support for HTTP streaming response and WebSockets is now on by default. Also, @serve.batch-decorated methods can stream responses.
• Train and Tune: Users are now expected to provide cloud storage or NFS path for distributed training or tuning jobs instead of a local path. This means that results written to different worker machines will not be directly synced to the head node. Instead, this will raise an error telling you to switch to one of the recommended alternatives: cloud storage or NFS. Please see ray-project/ray#37177 if you have questions.
• Data: We are introducing a new streaming integration of Ray Data and Ray Train. This allows streaming data ingestion for model training, and enables per-epoch data preprocessing. The DatasetPipeline API is also being deprecated in favor of Dataset with streaming execution.
• RLlib: Public alpha release for the new multi-gpu Learner API that is less complex and more powerful compared to our previous solution (blogpost). This is used under PPO algorithm by default.
