Hi,

LTS = 2.8.*

there is a problem in the LTS install in the router panel of the profiler:
Attempted to load class "Request" from namespace "Symfony\Bundle\WebProfilerBundle\Controller".
Did you forget a "use" statement for e.g. "Symfony\Component\HttpFoundation\Request" or "Symfony\Component\BrowserKit\Request"?

How to :

1. install a new lts version of symfony
   php symfony new hello_world lts
2. start the server
   php app/console server:start
3. get "/"
4. go to the Routing panel in the profiler

resolve :

add
use Symfony\Component\HttpFoundation\Request;
in
src/Symfony/Bundle/WebProfilerBundle/Controller/RouterController.php

regards,
