+
+Updated the `Observable` type to provide interoperability with `Symbol.observable`, making it compatible with at least `zen-observable` and `RxJS 7`.
+
+In cases where this change breaks tests that mocked the `Observable` type, the following addition to the mock should fix the breakage:
+
+```ts
+  [Symbol.observable]() {
+    return this;
+  },
+```
