+UPGRADE FROM 2.7 to 2.8
+=======================
+
+Translator
+----------
+ * The `getMessages()` method of the `Symfony\Component\Translation\Translator` was deprecated and will be removed in
+   Symfony 3.0. You should use the `getCatalogue()` method of the `Symfony\Component\Translation\TranslatorBagInterface`.
+
+   Before:
+
+   ```php
+   $messages = $translator->getMessages();
+   ```
+
+   After:
+
+   ```php
+    $catalogue = $translator->getCatalogue($locale);
+    $messages = $catalogue->all();
+
+    while ($catalogue = $catalogue->getFallbackCatalogue()) {
+        $messages = array_replace_recursive($catalogue->all(), $messages);
+    }
+   ```
