+# 19.0.0-next.1 (2024-08-22)
+
+## Breaking Changes
+
+### @angular-devkit/build-angular
+
+- The `browserTarget` option has been removed from the DevServer and ExtractI18n builders. `buildTarget` is to be used instead.
+
+### @angular-devkit/core
+
+- The deprecated `fileBuffer` function is no longer available. Update your code to use `stringToFileBuffer` instead to maintain compatibility.
+
+  **Note:** that this change does not affect application developers.
+
+### @angular/build
+
+- The `@angular/localize/init` polyfill will no longer be added automatically to projects. To prevent runtime issues, ensure that this polyfill is manually included in the "polyfills" section of your "angular.json" file if your application relies on Angular localization features.
