Oracle Java Platform Extension v26.0.0 for VS Code

Oracle's Apache-NetBeans-powered Java extension for VS Code shipped v26.0.0 on June 8 with four changes: VS Code variable substitution across 13 settings, a Run Configuration GUI panel in the Explorer sidebar, inline formatter settings via `jdk.format.options`, and a configurable Maven `settings.xml` path. At 5.86 million installs with a 4.62/5 rating (vs Red Hat's 3.32/5 at 54.9 million installs), the Oracle extension grows faster and rates higher, and adds three features Red Hat doesn't offer: interactive Java Notebook, built-in JShell REPL, and a JDK Downloader.

Helm Visualizer: browse your Kubernetes resources as a graph inside VS Code

Helm Visualizer (Beta) is a VS Code extension (v1.0.4, Apache 2.0) that renders Helm charts as interactive Kubernetes resource graphs with multi-environment diffing, a static Security Scanner across 7 vectors, and a Live Cluster Diff — all without requiring cluster access for most features. The June 6 v0.2.0 release adds the Security Scanner and Live Cluster Diff, marking the tool's expansion from a pure visualization aid into a delivery-verification tool. The main caveat: the VS Code panel currently requires a manually started `npm run dev` server, unlike typical plug-and-play extensions; the `helm viz` CLI plugin sidesteps this for terminal users.
