+- Add support for `components/**/.index.edge`. That means if you have a component in `components/button/index.edge`, completion and links will works for `@button` instead of `@button.index`.
+- Before, in order to show completions, you had to press `ctrl+space`. Now, completions will show automatically when you type `@` or `@.`. Same for `.ts` files, when you will start typing `edge.render`, completions will show automatically.
+- Add Edge built-in tags completions with some links to the documentation in the CompletionItem detail.
+- Use different icons for Edge built-in tags and custom tags.
