+
+
+### BREAKING CHANGES
+
+* **zone.js:** ZoneJS no longer swallows errors produced by `Object.defineProperty` calls.
+
+Prior to this change, ZoneJS monkey patched `Object.defineProperty` and if there is an error
+(such as the property is not configurable or not writable) the patched logic swallowed it
+and only console.log was produced. This behavior used to hide real errors,
+so the logic is now updated to trigger original errors (if any). One exception
+where the patch remains in place is `document.registerElement`
+(to allow smooth transition for code/polyfills that rely on old behavior in legacy browsers).
+If your code relies on the old behavior (where errors were not thrown before),
+you may need to update the logic to handle the errors that are no longer masked by ZoneJS patch.
