+* **upgrade:** support multi-slot projection in upgrade/static ([#14282](https://github.com/angular/angular/issues/14282)) ([914797a](https://github.com/angular/angular/commit/914797a)), closes [#14261](https://github.com/angular/angular/issues/14261)

+
+### BREAKING CHANGES
+
+* Perviously, any provider that had an ngOnDestroy lifecycle hook would be created eagerly.
+
+  Now, only classes that are annotated with @Component, @Directive, @Pipe, @NgModule are eager. Providers only become eager if they are either directly or transitively injected into one of the above.
+
+  This also makes all `useValue` providers eager, which
+  should have no observable impact other than code size.
+
+  **EXPECTED IMPACT**:
+  Making providers eager was an incorrect behavior and never documented.
+  Also, providers that are used by a directive / pipe / ngModule stay eager.
+  So the impact should be rather small.
+
+* DebugNode.source no longer returns the source location of a node.  
+
+  Closes 14013
+
+* core: (since v4 rc.1)
+  - `Renderer2.setStyle` no longer takes booleans but rather a
+     bit mask of flags.
