Dynatrace's SaaS release version 1.287 introduces several new features and enhancements, including improved observability for Linux on IBM Z mainframes through integrated log monitoring, which aims to streamline hybrid cloud management and reduce outages. The release also marks the deprecation of the VULNERABILITY_IMPACT_CHANGE_EVENTS event type, with suggested mitigation strategies available through alternative queries. Enhancements in Kubernetes observability now allow for better differentiation between running and allocatable pods, improved detection of node provider types, and new linking capabilities to ActiveGate deployment status. Additionally, this update enhances account security by notifying users of sign-ins from new browsers or locations and resolves various issues in application security, synthetic monitoring, RUM, and Dynatrace Cluster functionalities, with cumulative updates included to consolidate all previous changes.
