+
+
+### BREAKING CHANGES
+
+* Minified UMD bundles are no longer included in the distributed NPM packages.
+* **core:** Angular no longer maintains support for node v10
+* **core:** Previously the `ng.getDirectives` function threw an error in case a
+given DOM node had no Angular context associated with it (for example
+if a function was called for a DOM element outside of an Angular app).
+This behavior was inconsistent with other debugging utilities under `ng`
+namespace, which handled this situation without raising an exception.
+Now calling the `ng.getDirectives` function for such DOM nodes would
+result in an empty array returned from that function.
+* **compiler-cli:** Linked libraries no longer generate legacy i18n message ids. Any downstream
+application that provides translations for these messages, will need to
+migrate their message ids using the `localize-migrate` command line tool.
