Ray 1.0 has been released with a stable API and new serverless features, making it easier to build scalable libraries and applications. The update brings significant improvements in autoscaling, resource management, and community library integrations. Ray 1.0 now supports Java and Windows platforms, and its automated memory management eliminates "object evicted" errors. The release is the result of a large community effort with contributions from over 67 contributors and 458 commits. The update also introduces new serverless features, including production serving and detached actor lifetimes, and is backed by Anyscale's open source development model.
