Cloudflare has built EmDash, a new open-source CMS written entirely in TypeScript and powered by Astro. Plugins run in isolated Dynamic Workers, solving WordPress's decades-old plugin security crisis where 96% of security issues originate.

Vite+ Alpha drops today under MIT license, unifying Vite, Vitest, Oxlint, Oxfmt, and Rolldown into a single vp binary. Node.js runtime and package manager management included.

Google has open sourced JSIR, a next-generation JavaScript analysis tool built on MLIR. It supports both high-level dataflow analysis and lossless source-to-source transformation — used internally for Hermes bytecode decompilation and AI-powered JavaScript deobfuscation.

Vite 8.0.0 shipped stable on March 12, and the patch releases haven't stopped — v8.0.7 landed April 7 with fixes across CSS, SSR, WASM, and dev server behavior. A contrast to the long beta cycle.
