AsyncLocalStorageContextManager is a better context manager to use in all cases for Node.js 14.8.0 and later, and the current min supported Node.js is v18. AsyncLocalStorageContextManager is already used by default in NodeSDK setup. A recent indirect DoS vulnerability involving AsyncHook and stack overflow is the motivation for finally deprecating this class. https://nodejs.org/en/blog/vulnerability/january-2026-dos-mitigation-async-hooks The plan is to remove this in OTel JS SDK v3 (planned for mid-2025).
