Declarative compute configs for VM-based clouds (beta)​

February 27, 2026

You can now use declarative compute configs for Anyscale clouds backed by AWS EC2 or Google Cloud GCE. Specify CPU, memory, and GPU requirements with required_resources and optional required_labels for head and worker nodes; Anyscale selects and provisions VM instance types that match. This feature is in beta release. See Declarative compute configs.

Anyscale CLI version 0.26.87 released​

February 19, 2026

A new version of the Anyscale CLI and SDK is now available. See Version 0.26.87 release notes.

Custom tag normalization for cloud provider compatibility​

February 19, 2026

Anyscale now normalizes custom resource tags to ensure compatibility across all cloud providers. Anyscale converts uppercase letters to lowercase and strips periods (.) from tag keys and values. This changes previous behavior where tags with periods or uppercase letters silently failed to propagate to underlying cloud infra. See Custom tag requirements and limitations.

Anyscale operator for Kubernetes version 1.4.1 released​

February 19, 2026

Anyscale has released version 1.4.1 of the Anyscale operator for Kubernetes. For release details, see the Anyscale operator GitHub page.

Changes in 1.4.1:

  • AWS credential mount: You can now specify the signature version to use for S3 in the AWS credential mounting utility. This applies to the operator and all workloads.
  • Bug fixes:
    • Fixes a bug where the operator presented its client ID instead of its principal ID when verifying an Azure cloud with the Anyscale CLI.
    • Fixes a race condition with Kueue integration where the operator would be unable to remove the workload custom resource.

Ray 2.54.0 released​

February 17, 2026

Ray 2.54.0 has released and is available as an Anyscale base image.

See Ray 2.54.0 release highlights.

For all Python and system dependencies, see Anyscale base images.

Anyscale CLI version 0.26.86 released​

February 17, 2026

A new version of the Anyscale CLI and SDK is now available. See Version 0.26.86 release notes.

Support for Nvidia RTX Pro on AWS G7e instances​

February 17, 2026

Anyscale now supports G7e instance types on AWS clouds backed by VMs or EKS. These instances use Nvidia RTX Pro GPUs. See Compute configuration on Anyscale and pricing details for supported machine types.

Anyscale operator configuration for SYS_PTRACE​

February 11, 2026

warning

Process tracing (potential breaking change): Starting with Anyscale operator version 1.4.0, SYS_PTRACE is enabled by default for all Ray containers for profiling Ray processes and viewing actor flamegraphs and stack traces. If your cluster disallows SYS_PTRACE, pod creation will fail and disrupt workloads when autoscaling adds pods. Set workloads.enableProcessTracing: false in your Helm values to disable. See Workload features.

Anyscale operator for Kubernetes version 1.4.0 released​

February 11, 2026

Anyscale has released version 1.4.0 of the Anyscale operator for Kubernetes. For release details, see the Anyscale operator GitHub page.

Changes in 1.4.0:

  • AWS credential mount: Specify the S3 addressing style via the AWS credential mount; the setting applies to the operator and all workloads. See AWS credential mounting.
  • Kueue: Fixes for pods being recreated while waiting in the LocalQueue with multiple regions in the compute config, and for pods stuck in terminating (force-delete requires permissions to delete Kueue Workload CRs).
  • Other: Workload name label sanitization for invalid label values; fix for service token validation and header-based service version canary with the Gateway API.

Anyscale CLI version 0.26.85 released​

February 11, 2026

A new version of the Anyscale CLI and SDK is now available. See Version 0.26.85 release notes.

Removal of additional deprecated CLI and SDK commands​

February 11, 2026

Anyscale CLI version 0.26.85 removes the legacy machine CLI and several legacy SDK methods. See Methods removed in version 0.26.85 for migration guidance.

Restrict collaborator permissions on container images​

February 9, 2026

Organization owners can now restrict permissions on container images for collaborators. This feature is in beta release and you must request access. Use new roles to prevent users from creating images or to deny deploying clusters with Anyscale base images. See Container image roles.

Anyscale CLI version 0.26.84 released​

February 6, 2026

A new version of the Anyscale CLI and SDK is now available. See Version 0.26.84 release notes.

New directories excluded from Anyscale working directories​

February 4, 2026

Anyscale now excludes the following directories when uploading files in the working_dir for Ray workloads: .git, .venv, venv, and __pycache__. Set RAY_OVERRIDE_RUNTIME_ENV_DEFAULT_EXCLUDES='' to include all directories. This change establishes parity between Anyscale and Ray default behaviors.

Update cloud default system storage to use enhanced CORS​

February 4, 2026

Anyscale has released a new CLI command to update the default system storage container configured for an Anyscale cloud to enhance CORS support. Anyscale uses these settings for an optimized file viewer experience. New clouds deployed with anyscale cloud setup use this setting by default. See Update CORS settings for default system storage.

Anyscale CLI version 0.26.83 released​

February 4, 2026

A new version of the Anyscale CLI and SDK is now available. See Version 0.26.83 release notes.

Deprecated support for concurrency job runs with job queues​

February 3, 2026

Anyscale has deprecated support for setting max_concurrency greater than one for job queues and has turned off this setting by default in clouds not using this feature. See Concurrent jobs in job queues.

New user and IAM management experience in the Anyscale console​

February 2, 2026

Organization owners can now use a unified UI to manage users and permissions in the Anyscale console. Click on your user icon and select Users & IAM. See Roles and permissions.
