Dynatrace SaaS version 1.304 introduces significant updates and breaking changes, including the adoption of new Semantic Dictionary conventions for AWS container and OCSF vulnerability findings, which necessitate redeployment of previous dashboards and workflows. The release enhances log attribute processing by treating it like content attributes, thereby accommodating larger data sizes, and introduces new customization options for data visualizations in Dashboards and Notebooks, along with a feedback feature for Notebooks. Additionally, it allows more data types for the dt.security_context in OpenPipeline and combines bucket and record-level permissions in Grail. The update also includes cumulative patches that address various resolved issues, such as anomaly detector functionality in Dynatrace Cluster, bug fixes in Session Replay, and improvements in Service-Level Objectives migration from Managed to SaaS environments.
