+
+
+### Bug Fixes
+
+* **animations:** cleanup DOM elements when the root view is removed ([#41059](https://github.com/angular/angular/issues/41059)) ([c49b280](https://github.com/angular/angular/commit/c49b28013a6c017c9afc73bbc00bb4fdcf15c70e))
+* **compiler-cli:** add `useInlining` option to type check config ([#41043](https://github.com/angular/angular/issues/41043)) ([09aefd2](https://github.com/angular/angular/commit/09aefd29045db77689f4dc16a6abae09a79cfb81)), closes [#40963](https://github.com/angular/angular/issues/40963)
+* **core:** detect synthesized constructors that have been downleveled using TS 4.2 ([#41305](https://github.com/angular/angular/issues/41305)) ([274dc15](https://github.com/angular/angular/commit/274dc15452739e4fab2f647804a64d5b797cfed5)), closes [#41298](https://github.com/angular/angular/issues/41298)
+* **ngcc:** detect synthesized constructors that have been downleveled using TS 4.2 ([#41305](https://github.com/angular/angular/issues/41305)) ([8d3da56](https://github.com/angular/angular/commit/8d3da56eda12070df1fb473c8609f3a94d77bfd6)), closes [#41298](https://github.com/angular/angular/issues/41298)
+* **router:** fragment can be null ([#37336](https://github.com/angular/angular/issues/37336)) ([b555160](https://github.com/angular/angular/commit/b5551609fe02787641bdfdb0a6edfded413a3b52)), closes [#23894](https://github.com/angular/angular/issues/23894) [#34197](https://github.com/angular/angular/issues/34197)
+
+
+### Features
+
+* **router:** add migration for ActivatedRouteSnapshot.fragment ([#41092](https://github.com/angular/angular/issues/41092)) ([190fa07](https://github.com/angular/angular/commit/190fa07b9a416defb581d2bf76d1deef7baefce6)), closes [#37336](https://github.com/angular/angular/issues/37336)
+
+
+### BREAKING CHANGES
+
+* **animations:** DOM elements are now correctly removed when the root view is removed.
+If you are using SSR and use the app's HTML for rendering, you will need
+to ensure that you save the HTML to a variable before destorying the
+app.
+It is also possible that tests could be accidentally relying on the old behavior by
+trying to find an element that was not removed in a previous test. If
+this is the case, the failing tests should be updated to ensure they
+have proper setup code which initializes elements they rely on.
+* **router:** Strict null checks will report on fragment potentially being null.
+Migration path: add null check.
+

+### Bug Fixes
