+### DEP0085: AsyncHooks Sensitive API
+
+Type: Runtime
+
+The AsyncHooks Sensitive API was never documented and had various of minor
+issues, see https://github.com/nodejs/node/issues/15572. Use the `AsyncResource`
+API instead.
+
+
+<a id="DEP0086"></a>
+### DEP0086: Remove runInAsyncIdScope
+
+Type: Runtime
+
+`runInAsyncIdScope` doesn't emit the `before` or `after` event and can thus
+cause a lot of issues. See https://github.com/nodejs/node/issues/14328 for more
+details.
