Overview

This page tracks releases of the BYOC (Bring Your Own Cloud) Logs binary, distributed as a Docker image and bundled by the datadog/cloudprem Helm chart. New features and fixes ship in the binary; the chart packages them for deployment.

Check your installed binary version

Look at the image field on a BYOC Logs pod:

kubectl get pods -n <BYOC_LOGS_NAMESPACE> \
  -o jsonpath='{range .items[*]}{.spec.containers[*].image}{"\n"}{end}' \
  | sort -u

The image tag (for example, :v0.1.26) is the binary version. To see which binary version a Helm chart bundles, run:

helm show chart datadog/cloudprem --version <CHART_VERSION> | grep appVersion

Upgrade

Binary upgrades ship through the Helm chart. See Install BYOC Logs for the chart upgrade command for your platform.

Releases

v0.1.31 — 2026-07-08

Bundled in chart: 0.4.5.

Changed

• Fixes single-token phrase prefix queries on raw fields so match_phrase_prefix searches return all matching prefix terms instead of being capped by max_expansions.
• Up to 3x faster intersection for selective terms queries with time range.

Helm chart changes

• Adds indexer.volumeAttributesClass and searcher.volumeAttributesClass values to provision Kubernetes VolumeAttributesClass resources for indexer and searcher persistent volumes. Use these values to tune volume attributes such as IOPS and throughput. This feature is disabled by default, requires Kubernetes 1.31 or later, and requires driverName when enabled.
• Fixes the Kubernetes advertise address by setting KUBERNETES_POD_IP from the pod IP instead of the pod name.
• Disables serviceAccount.automountServiceAccountToken by default to reduce token exposure on pods that do not need Kubernetes API access.
• Enables securityContext.readOnlyRootFilesystem by default across workloads for defense-in-depth hardening.

v0.1.30 — 2026-06-30

Bundled in chart: 0.4.3.

Changed

• Reduces search CPU time for nested date histogram queries by up to 20%, with the largest gains on seven-day windows.
• Adds a dedicated health check listener on port 7284 for CloudPrem component liveness and readiness checks.

Helm chart changes

• Adds global volumes and volumeMounts values that apply to all CloudPrem components and merge with existing per-component extraVolumes and extraVolumeMounts.
• Adds global topologySpreadConstraints support, merged with per-component constraints, to spread CloudPrem workload pods across topology domains.
• Updates CloudPrem services and AWS ALB internal ingress health checks to use the dedicated health endpoint.

v0.1.29 — 2026-06-05

Bundled in chart: 0.4.2.

Changed

• Faster execution for common log analysis queries, including 2x faster range queries, 1.6x faster cardinality aggregations, and up to 6x faster intersections with range queries.
• Treats field:* filters as existence queries, and fixes sorting by percentile aggregations.
• Reduced memory usage for Google Cloud Storage uploads to improve indexing stability.

Helm chart changes

• Enables BYOC service telemetry by default with datadog.byocTelemetry.enabled; this exports BYOC service logs and metrics only, not customer-ingested logs, metrics, or traces.
• Deprecates and ignores cloudprem.index.retention, and no longer sets CP_RETENTION_PERIOD.

v0.1.26 — 2026-05-05

Bundled in chart: 0.4.0.

Changed

• Up to 4x faster term aggregations with order by sub aggregation and up to 1.5x faster cardinality aggregations.
