Dynatrace Managed version 1.300, with its release rollout starting on September 16, 2024, and updated on December 5, 2024, introduces several new features and enhancements, notably the ability to sort the "Assign environment permissions to user groups" table by column in the CMC and enhancements to Kubernetes events fields for Classic Events. The update also improves the handling of metric selector events, resolves high CPU issues in some Cassandra deployments, and includes a series of resolved issues, such as fixing duplicate problem references and improving notification email handling. Additionally, the release includes changes to operating system support, with several Linux versions being phased out over the coming years, and cumulative updates that address issues in previous builds, including adjustments to accommodate new Firewalld settings in Red Hat Enterprise Linux 9.5.
