Please refer to the 7.79.1 tag on integrations-core for the list of changes on the Core Checks

Bump github.com/prometheus/prometheus to v0.311.4 to address CVE-2026-42151 and CVE-2026-42154.

Windows: Fix CD-ROM drives being monitored by the disk check since Agent 7.73.0. The diskv2 check now uses the Windows GetDriveType() API to properly detect and exclude CD-ROM drives, matching the behavior of the previous Python disk check. This fixes false alerts on system.disk.in_use for CD-ROM drives with inserted media.
Fix a bug in the workload autoscaling controller where annotation-only edits (e.g. autoscaling.datadoghq.com/preview) on a locally-owned DatadogPodAutoscaler were not picked up until the next .spec change or cluster-agent restart, because the controller gated re-sync on .metadata.generation (which annotations do not bump). Toggling burstable mode via the preview annotation now takes effect on the next reconcile.
MacOS agent GUI app needs to ignore SIGPIPE to avoid process termination.
On macOS, preserve user customizations to system-probe.yaml across Agent upgrades.
Fixed a bug on Windows where the NPM TCP failure rate could exceed 100% and climb indefinitely.
