 * Flash Messages now returns and array based on type (the old method are still available but deprecated)
 
-  Before (PHP):
-
-    <?php if ($view['session']->hasFlash('notice')): ?>
-        <div class="flash-notice">
-            <?php echo $view['session']->getFlash('notice') ?>
-        </div>
-    <?php endif; ?>

-  After (PHP):
-
-    <?php if ($view['session']->getFlashBag()->has('notice')): ?>
-        <div class="flash-notice">
-            <?php echo $view['session']->getFlashBag()->get('notice') ?>
-        </div>
-    <?php endif; ?>

-  If you wanted to process all flash types you could also make use of the `getFlashBag()->all()` API:
-
-      <?php foreach ($view['session']->getFlashBag()->all() as $type => $flash): ?>
-          <div class="flash-$type">
-              <?php echo $flash; ?>
-          </div>
-      <?php endforeach; ?>
