TauGrid v0.4.0

TauGrid v0.4.0

TauGrid v0.4.0 publishes the tau and tau-gen command-line tools together
with aligned TauGrid 0.4.0 images and Helm charts.

Highlights

• Add tau logs <run-name> to discover runs across the connected workspace
  and cached workspace connections, with consistent Job and Ray log streaming.
• Make GPU-backed tau serve deploy workloads inherit topology-aware
  scheduling annotations and GPU node tolerations for Deployments and
  RayServices.
• Preserve workspace identity and scope when Portal reads durable run history
  in single-workspace and managed multi-workspace deployments.
• Scope the built-in workload-profile catalog to the configured workspace
  namespace across Helm and Terraform installations.
• Align Terraform's Azure Data Explorer defaults with production deployments
  by enabling streaming ingestion and using Standard_E8ads_v5 with capacity
  4.

Upgrade notes

• Terraform users who rely on the default Azure Data Explorer SKU or capacity
  should review the plan before applying. To retain the previous evaluation
  defaults, set adx_sku_name = "Dev(No SLA)_Standard_D11_v2",
  adx_sku_capacity = 1, and adx_streaming_ingestion_enabled = false.
• tau run logs <run-name> remains available as a compatibility path;
  tau logs <run-name> is the recommended command.

Compatibility

• Public environment variables keep the TAU_ prefix.
• Kubernetes metadata and workspace APIs keep the tau.azure.com domain.
• experiment and portal commands continue to require the separate
  taugrid-portal binary.
• The Python SDK keeps its independent package version.

Install

Install the Tau CLI with the release quickstart script:

curl -fsSL \
  https://github.com/Azure/taugrid/releases/download/v0.4.0/install.sh | sh

export PATH="$HOME/.local/bin:$PATH"
tau version --short

The installer detects Linux or macOS on amd64 or arm64, verifies the published
checksums, and installs tau under $HOME/.local/bin. The matching tau-gen
binary and Python SDK wheel remain available as release assets.
