+#### Upgrading from `2.x` to `3.0`
+The repository now requires PHP 8.4 or higher. Ensure your environment is updated accordingly.
+
+The E_STRICT error level constant has been removed from Kodus\Sentry\Extensions due to its deprecation and removal in PHP 8.4. Replace any references to E_STRICT in your code, as it is no longer necessary. PHP 8.4 enforces stricter standards as part of E_ALL.
+
 #### Upgrading from `1.x` to `2.0`
 
 The constructor signature of `SentryClient` has changed.
