+### Performance Improvements
+
+* switch angular to use StaticInjector instead of ReflectiveInjector ([fcadbf4](https://github.com/angular/angular/commit/fcadbf4)), closes [#18496](https://github.com/angular/angular/issues/18496)
+
+
+### BREAKING CHANGES
+
+* `platformXXXX()` no longer accepts providers which depend on reflection.
+Specifically the method signature when from `Provider[]` to
+`StaticProvider[]`.
+
+Example:
+Before:
+```
+[
+  MyClass,
+  {provide: ClassA, useClass: SubClassA}
+]
+
+```
+
+After:
+```
+[
+  {provide: MyClass, deps: [Dep1,...]},
+  {provide: ClassA, useClass: SubClassA, deps: [Dep1,...]}
+]
+```
+
+NOTE: This only applies to platform creation and providers for the JIT
+compiler. It does not apply to `@Component` or `@NgModule` provides
+declarations.
+
+Benchpress note: Previously Benchpress also supported reflective
+provides, which now require static providers.
+
+DEPRECATION:
+
+- `ReflectiveInjector` is now deprecated as it will be remove. Use
+  `Injector.create` as a replacement.
