+## Upcoming
+
+This release drops support of legacy runtime environments ([Level/community#98](https://github.com/Level/community/issues/98)):
+
+- Internet Explorer 11
+- Safari 9-11
+- Stock Android browser (AOSP).
+
+In browsers, the [`immediate`](https://github.com/calvinmetcalf/immediate) shim for `process.nextTick()` has been replaced with the smaller [`queue-microtask`](https://github.com/feross/queue-microtask), except in streams.
