October 2025 — StackRox delivered the Sensitive File Activity Monitoring Agent feature behind a feature flag, introducing the Fact component for Sensitive File Activity monitoring. The feature is gated by ROX_SENSITIVE_FILE_ACTIVITY and includes deployment/config support via image configurations, environment variables, and Helm chart templates. This enables controlled rollout, safer production exposure, and enhanced visibility for file activity monitoring to support policy enforcement and incident response.

August 2025: Observability improvement in stackrox/collector by downgrading NetworkStatusNotifier log verbosity. Two log messages were moved from DEBUG to TRACE to reduce noise while preserving actionable debugging information. Change implemented in commit 0b3e203d4cca82c9fe7249f35546f0c89010ee6d (#2329). Business value includes lower log storage/processing costs and faster incident triage with no API changes or customer-facing impact.
