Node.js has released two updates on the same day: version 26.12.0 for the Current line and version 24.22.0 "Krypton" for the active LTS. The Current release focuses on performance and includes websocket mask helpers, improved error messages for missing WebAssembly and RX support, and ongoing work on synchronous ES module loading. In contrast, the LTS release introduces significant cryptographic enhancements, such as PKCS12 parsing, SIV encryption modes, and new native utilities for throttling and debouncing. Both updates are backward-compatible, making the upgrade process low-risk, but users should still test against their workloads before deploying

Node.js 26.12.0 and 24.22.0 Krypton: What Changed and How to Upgrade

Node.js shipped two point releases on the same day, adding Node.js 26.12.0 to the Current line and Node.js 24.22.0 "Krypton" to the active LTS. The Current release delivers websocket mask helpers, clearer errors for missing WebAssembly and RX support, and steady progress on synchronous ESM loading, though it stays lean overall. The LTS line is the more developer-facing upgrade, packing a crypto-heavy refresh, including PKCS12 parsing, SIV encryption modes, and provider-aware cipher discovery, alongside native throttle, debounce, and bound-socket transfer utilities. Both are backward-compatible, so upgrading is low risk, but teams should still test against their own workloads before shipping.
