Router.php rev. 1429 problems?

[eluser]Unknown[/eluser]
Hello,

I've updated to the last CI revision, and my site index "/" stop working.
In my routes config I have:
for example:
$route['(:any)'] = 'users/index/$3';
$route['default_controller'] = "mymaincontroller";

for www.mysite.com I need to call mymaincontroller and not users controller.

any ideas?.
