+# 19.2.16 (2025-09-10)
+
+## Breaking Changes
+
+### @angular/ssr
+
+- The server-side bootstrapping process has been changed to eliminate the reliance on a global platform injector.
+
+  Before:
+
+  ```ts
+  const bootstrap = () => bootstrapApplication(AppComponent, config);
+  ```
+
+  After:
+
+  ```ts
+  const bootstrap = (context: BootstrapContext) =>
+    bootstrapApplication(AppComponent, config, context);
+  ```
