+- HTML, style values, and URLs are now automatically sanitized. Values that do not match are escaped
+  or ignored. When binding a URL or style property that would get ignored, bind to a value
+  explicitly marked as safe instead by injection the DOM sanitization service:
+  ```
+  class MyComponent {
+    constructor(sanitizer: DomSanitizationService) {
+      // ONLY DO THIS FOR VALUES YOU KNOW TO BE SAFE! NEVER ALLOW USER DATA IN THIS!
+      this.safeStyleValue = sanitizer.bypassSecurityTrustStyle('rotate(90deg)');
+      // then bind to `safeStyleValue` in your template.
+    }
+  }
+  ```
