+### DEP0098: AsyncHooks Embedder AsyncResource.emit{Before,After} APIs
+
+Type: Runtime
+
+The embedded API provided by AsyncHooks exposes emit{Before,After} methods
+which are very easy to use incorrectly which can lead to unrecoverable errors.
+
+Use [`asyncResource.runInAsyncScope()`][] API instead which provides a much
+safer, and more convenient, alternative. See
+https://github.com/nodejs/node/pull/18513 for more details.
