-#### Support `@let` declaration syntax (#16474 by @sosukesuzuki)
-
-Adds support for Angular v18 `@let` declaration syntax.
-
-Please see the following code example. The `@let` declaration allows you to define local variables within the template:
-
-<!-- prettier-ignore -->
-```html
-@let name = 'Frodo';
-
-<h1>Dashboard for {{name}}</h1>
-Hello, {{name}}
-```
-
-For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).
-
-We also appreciate the Angular Team for kindly answering our questions to implement this feature.
