+# CHANGELOG
+
+## NEXT
+
+-   Minimum PHP version was bumped to 8.0 so that PHP 8 attributes could be used.
+
+-   The `LiveComponentInterface` was dropped and replaced by the `AsLiveComponent` attribute,
+    which extends the new `AsTwigComponent` from the TwigComponent library. All
+    other annotations (e.g. `@LiveProp` and `@LiveAction`) were also replaced by
+    PHP 8 attributes.
+
+Before:
+
+```php
+use App\Entity\Notification;
+use App\Repository\NotificationRepository;
+use Symfony\UX\LiveComponent\Attribute\LiveAction;
+use Symfony\UX\LiveComponent\Attribute\LiveProp;
+use Symfony\UX\LiveComponent\LiveComponentInterface;
+
+final class NotificationComponent implements LiveComponentInterface
+{
+    private NotificationRepository $repo;
+
+    /** @LiveProp */
+    public bool $expanded = false;
+
+    public function __construct(NotificationRepository $repo)
+    {
+        $this->repo = $repo;
+    }
+
+    /** @LiveAction */
+    public function toggle(): void
+    {
+        $this->expanded = !$this->expanded;
+    }
+
+    public function getNotifications(): array
+    {
+        return $this->repo->findAll();
+    }
+
+    public static function getComponentName(): string
+    {
+        return 'notification';
+    }
+}
+```
+
+After:
+
+```php
+use App\Entity\Notification;
+use App\Repository\NotificationRepository;
+use Symfony\UX\LiveComponent\Attribute\AsLiveComponent;
+use Symfony\UX\LiveComponent\Attribute\LiveAction;
+use Symfony\UX\LiveComponent\Attribute\LiveProp;
+
+#[AsLiveComponent('notification')]
+final class NotificationComponent
+{
+    private NotificationRepository $repo;
+
+    #[LiveProp]
+    public bool $expanded = false;
+
+    public function __construct(NotificationRepository $repo)
+    {
+        $this->repo = $repo;
+    }
+
+    #[LiveAction]
+    public function toggle(): void
+    {
+        $this->expanded = !$this->expanded;
+    }
+
+    public function getNotifications(): array
+    {
+        return $this->repo->findAll();
+    }
+}
+```
+
+## Pre-Release
+
+-   The LiveComponent library was introduced!

+# CHANGELOG
+
+## NEXT
+
+-   Minimum PHP version was bumped to 8.0 so that PHP 8 attributes could be used.
+
+-   The `ComponentInterface` was dropped and replaced by the `AsTwigComponent` attribute.
+    The `getComponentName()` was replaced by a `name` argument to the attribute.
+
+Before:
+
+```php
+use Symfony\UX\TwigComponent\ComponentInterface;
+
+class AlertComponent implements ComponentInterface
+{
+    public string $type = 'success';
+    public string $message;
+
+    public static function getComponentName(): string
+    {
+        return 'alert';
+    }
+}
+```
+
+After:
+
+```php
+use Symfony\UX\TwigComponent\Attribute\AsTwigComponent;
+
+#[AsTwigComponent('alert')]
+class AlertComponent
+{
+    public string $type = 'success';
+    public string $message;
+}
+```
+
+-   If you're using a version _lower_ than Symfony 5.3, you will need
+    to manually tag all component services with `twig.component`. This is
+    because Symfony 5.3 introduces autoconfiguration for PHP 8 attributes,
+    which this library leverages.
+
+-   The template for a component can now be controlled via the `template` argument
+    to the `AsTwigComponent` attribute:
+
+```php
+use Symfony\UX\TwigComponent\Attribute\AsTwigComponent;
+
+#[AsTwigComponent('alert', template: 'other/path/alert.html.twig')]
+class AlertComponent
+{
+    // ...
+}
+```
+
+## Pre-Release
