This document explains how to upgrade from one Symfony2 PR version to the next one. It only discusses changes that need to be done when using the "public" API of the framework. If you "hack" the core, you should probably follow the timeline closely anyway.
-
The
trans
tag does not accept a message as an argument anymore:{% trans "foo" %} {% trans foo %}
Use the long version the tags or the filter instead:
{% trans %}foo{% endtrans %} {{ foo|trans }}
This has been done to clarify the usage of the tag and filter and also to make it clearer when the automatic output escaping rules are applied (see the doc for more information).
-
Some methods in the DependencyInjection component's ContainerBuilder and Definition classes have been renamed to be more specific and consistent:
Before:
$container->remove('my_definition'); $definition->setArgument(0, 'foo');
After:
$container->removeDefinition('my_definition'); $definition->replaceArgument(0, 'foo');
-
In the rememberme configuration, the token_provider key now expects a real service id instead of only a suffix.
-
HttpFoundation\Cookie::getExpire() was renamed to getExpiresTime()
-
XML configurations have been normalized. All tags with only one attribute have been converted to tag content:
Before:
<bundle name="MyBundle" /> <app:engine id="twig" /> <twig:extension id="twig.extension.debug" />
After:
<bundle>MyBundle</bundle> <app:engine>twig</app:engine> <twig:extension>twig.extension.debug</twig:extension>
-
Fixes a critical security issue which allowed all users to switch to arbitrary accounts when the SwitchUserListener was activated. Configurations which do not use the SwitchUserListener are not affected.
-
Extension configuration classes should now implement the
Symfony\Component\Config\Definition\ConfigurationInterface
interface. Note that the BC is kept but implementing this interface in your extensions will allow for further developments. -
The "fingerscrossed" Monolog option has been renamed to "fingers_crossed".
-
Bundle logical names earned back their
Bundle
suffix:Controllers:
Blog:Post:show
->BlogBundle:Post:show
Templates:
Blog:Post:show.html.twig
->BlogBundle:Post:show.html.twig
Resources:
@Blog/Resources/config/blog.xml
->@BlogBundle/Resources/config/blog.xml
Doctrine:
$em->find('Blog:Post', $id)
->$em->find('BlogBundle:Post', $id)
-
ZendBundle
has been replaced byMonologBundle
. Have a look at the changes made to Symfony SE to see how to upgrade your projects: https://github.com/symfony/symfony-standard/pull/30/files -
Almost all core bundles parameters have been removed. You should use the settings exposed by the bundle extension configuration instead.
-
Some core bundles service names changed for better consistency.
-
Namespace for validators has changed from
validation
toassert
(it was announced for PR9 but it was not the case then):Before:
@validation:NotNull
After:

Moreover, the
Assert
prefix used for some constraints has been removed (AssertTrue
toTrue
). -
ApplicationTester::getDisplay()
andCommandTester::getDisplay()
method now return the command exit code
-
Symfony\Bundle\FrameworkBundle\Util\Filesystem
has been moved toSymfony\Component\HttpKernel\Util\Filesystem
-
The
Execute
constraint has been renamed toCallback
-
The HTTP exceptions classes signatures have changed:
Before:
throw new NotFoundHttpException('Not Found', $message, 0, $e);
After:
throw new NotFoundHttpException($message, $e);
-
The RequestMatcher class does not add
^
and$
anymore to regexp.You need to update your security configuration accordingly for instance:
Before:
pattern: /_profiler.* pattern: /login
After:
pattern: ^/_profiler pattern: ^/login$
-
Global templates under
app/
moved to a new location (old directory did not work anyway):Before:
app/views/base.html.twig app/views/AcmeDemoBundle/base.html.twig
After:
app/Resources/views/base.html.twig app/Resources/AcmeDemo/views/base.html.twig
-

-
Assetic filters must be now explicitly loaded:
assetic: filters: cssrewrite: ~ yui_css: jar: "/path/to/yuicompressor.jar" my_filter: resource: "%kernel.root_dir%/config/my_filter.xml" foo: bar
