The Firewall is now executed after the Router. This was needed to have access
to the locale and other request attributes that are set by the Router. This
change implies that all Firewall specific URLs have proper (empty) routes like
`/login_check` and `/logout`.
* 2.0:
[HttpKernel] fixed Content-Length header when using ESI tags (closes#2623)
[HttpFoundation] added an exception to MimeTypeGuesser::guess() when no guesser are available (closes#2636)
[Security] fixed HttpUtils::checkRequestPath() to not catch all exceptions (closes#2637)
[DoctrineBundle] added missing default parameters, needed to setup and use DBAL without ORM
[Transation] Fix grammar.
[TwigBundle] Fix trace to not show 'in at line' when file/line are empty.
The locale management does not require sessions anymore.
In the Symfony2 spirit, the locale should be part of your URLs. If this is the case
(via the special _locale request attribute), Symfony will store it in the request
(getLocale()).
This feature is now also configurable/replaceable at will as everything is now managed
by the new LocaleListener event listener.
How to upgrade:
The default locale configuration has been moved from session to the main configuration:
Before:
framework:
session:
default_locale: en
After:
framework:
default_locale: en
Whenever you want to get the current locale, call getLocale() on the request (was on the
session before).
This change removes the need for the {_locale} hack.
Now, all paths in the Security component can be:
* An absolute path (/login)
* An absolute URL (http://symfony.com/login)
* A route name (login)
So, if you want to use a path that includes a global parameter (like _locale),
use a route instead of a path.
