+This release switches the SDK to use [`AsyncLocalStorage`](https://nodejs.org/api/async_context.html#class-asynclocalstorage) as the async context isolation mechanism in the SDK for Node 14+. For Node 10 - 13, we continue to use the Node [`domain`](https://nodejs.org/api/domain.html) standard library, since `AsyncLocalStorage` is not supported there. **Preliminary testing showed [a 30% improvement in latency and rps](https://github.com/getsentry/sentry-javascript/issues/7691#issuecomment-1504009089) when making the switch from domains to `AsyncLocalStorage` on Node 16.**
