Runtimes

Node.js closed the 19,000-line VFS pull request that split the project over AI-generated code, after its functionality shipped through smaller PRs and the TSC adopted a formal AI use policy.

Node.js 26.9.0 adds a global Worker class implementing the WHATWG Web Worker API and enables the experimental node:ffi module by default.

TinyGo 0.42 makes previously fatal runtime panics recoverable via defer and recover, adds a minimal UEFI compile target, and the project followed with its first official hardware starter kit built with Seeed Studio.

TornadoVM 6.0 removes its JNI and JVMCI dependencies, unifying Java GPU acceleration into one build spanning JDK 21 through 27 while retiring three hardware backends.

Bun 1.4, released August 20, is the first stable version built entirely on the runtime's contested Rust rewrite, delivering 30x faster package installs and 5x lower idle CPU usage.

Deno 2.9, released June 25, adds an experimental deno desktop command that compiles web projects into single-binary native apps using the OS webview by default.

Deno 2.8, released May 22, adds deno audit fix, deno pack, deno ci, deno transpile, deno why, and deno bump-version, while slashing cold npm install times by 3.66x and enabling Chrome DevTools network traffic inspection.

Anthropic's first major Bun release since acquiring the runtime tackles long-running-process leaks, adds isolate, parallel and shard test flags, and lands days after Pulumi made Bun a fully supported infrastructure-as-code runtime.

The open-source runtime executes Node.js v24 applications inside a WASIX sandbox without Docker, passing 99 percent of the Node.js test suite while trading 5 to 30 percent of native performance for process-level isolation.

Systemd 260 removes SysV init script support, introduces OverlayFS-based mstack container tooling, adds a Varlink metrics framework, and raises the minimum kernel to Linux 5.10.

The next Kubernetes release locked its feature set on March 18, delivering 80 enhancements that graduate User Namespaces and four Dynamic Resource Allocation features to GA while introducing gang scheduling and workload-aware placement for AI training clusters.

Deno 2.7 ships stable Temporal date/time API, official Windows ARM builds, npm overrides, and over 40 Node.js compatibility fixes in its February 25 release.
