The Structure tool window now includes a Logical code structure alongside the familiar Physical structure. This allows you to view not only classes, methods, and fields but also the links and interactions between components in your project. For example, when you open a controller in a Spring Boot application, you can see its endpoints and the autowired application components. This enhanced view helps you understand the project structure and allows you to navigate through the project by following both code usages and meaningful connections.

We've made debugging Kubernetes applications even easier. You can activate tunnel debugging simply by clicking on the ellipsis next to the Debug button and selecting Add Tunnel for Remote Debug. This makes your workstation a virtual part of the Kubernetes cluster, allowing you to swap in a pod and debug microservices locally with your preferred tools. Other microservices will interact with your workstation as though it's the pod you're debugging, with full network access to the rest of the cluster.

IntelliJ IDEA now offers cluster-wide Kubernetes log access with streaming and pattern matching – essential tools for developers, as well as DevOps and SRE teams. This feature provides a centralized view of all events across pods, nodes, and services, helping you quickly identify issues without manually checking each log. Real-time streaming enables immediate diagnostics, while pattern matching automates the detection of key events and errors, such as out-of-memory issues or unusual network activity.

In IntelliJ IDEA 2024.3, K2 mode has officially moved out of Beta and is now Stable and ready for general use. K2 mode significantly improves code analysis stability, memory consumption efficiency, and the IDE’s overall performance. K2 mode now offers improved feature-parity with Java, and support for all Kotlin 2.1 features. To explore its capabilities, go to Settings/Preferences | Languages & Frameworks | Kotlin.
