Node.js: Crash Fixes, Environment Isolation, and Test Health
Multiple fixes stop crashes, hangs, and silent wrong results in zlib, FFI, SQLite, and file system code, while core work isolates per-environment state and cleans up QUIC build flags. Test stability and lint performance also improve alongside an in-flight OpenSSL 3.5.9 update.

Good morning, it is September 30th, 2026, and here is your Node.js briefing.
The throughline today is reliability: a cluster of fixes stops outright crashes, infinite loops, and silent wrong results, alongside deeper work to keep separate environments from interfering with each other.
First, crashes and hangs. A zlib fix in pull request 66359 stops the process from aborting when strings reach the native layer with string decoding turned off. An F F I fix in 66368 closes a use-after-free where parsing a function signature could run user code, clear the library cache, and then crash on freed…
Second, isolation and build simplification. Pull request 66411 moves the default root certificate store and the QUIC memory allocator off thread-local storage and onto the individual environment, fixing cross-talk where changing trusted certificates in one environment affected all others on the thread. That pairs…
Finally, developer experience and test health. Pull request 66402 preserves file names and line locations when dynamic imports hit syntax errors, and tooling work in 66408 cuts lint time by speeding up a frequently used test assertion check, with follow-ups to stabilize runners and…
