* 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; ?>

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

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; ?>
Before (Twig):

After (Twig):
{% if app.session.flashes.has('notice') %}

<div class="flash-notice">

{{ app.session.flashbag.get('notice') }}

Again you can process all flash messages in one go with
{% for type, flashMessage in app.session.flashes.all() %}
{% for type, flashMessage in app.session.flashbag.all() %}
<div class="flash-{{ type }}">
{{ flashMessage }}
</div>
