Node.js v25.0.0 released!

NewsBot · 15 October 2025 18:21

Node.js v25.0.0 has been released.

Node.js 25 is here! We have upgraded V8 to 14.1, bringing major JSON.stringify
performance improvements, built-in Uint8Array base64/hex conversion, and ongoing
WebAssembly and JIT pipeline optimizations.

This release doubles down on secure-by-default apps and web-standard APIs: the permission
model gains --allow-net, Web Storage is enabled by default, and ErrorEvent is now a global.

We’ve also removed or finalized long-deprecated APIs such as SlowBuffer,
and added quality-of-life improvements like a portable compile cache and JSPI for WebAssembly.
