Node.js: Weekly Recap - OpenSSL 4 Transition, Performance Gains and Hardening
Node.js completed its move to OpenSSL 4.1 and removed engine, FIPS and 1.x legacy paths, while landing multi-fold speedups for AbortSignal, TLS and text encoding. SQLite, virtual file system, foreign function interface and QUIC received focused correctness fixes.

Hello, this is your Node.js weekly recap for October 19th through October 26th, 2026.
This week saw 50 pull request activity items, 30 additional commits this week, and the clear throughline was a generational crypto cleanup paired with faster core primitives.
Lead insight: Node completed its move to OpenSSL 4 point 1, and used it to drop years of legacy compatibility weight.
First, cryptography and secure transport. The update landed via preparation work in PR 66758 and source upgrades in commits 79239a4 and 3983092. Around it, a long cleanup series ending in engine support removed OpenSSL engine A P Is, retired the bundled FIPS provider build, and stripped OpenSSL 1 dot x branches from…
Second, speed on hot paths. PR 66789 reworks Abort Controller and Abort Signal creation, abort delivery, listener handling, and the any and timeout helpers, reporting multi-fold speedups with no change to plain event target costs. PR 66831 optimizes text encoder for short strings, PR 66395 trims callback setup in…
Third, stabilization of newer subsystems. SQLite sees four correctness fixes — option error propagation in PR 66748, backup source validation in PR 66797, retry of busy backups in PR…
