Hi,
So i recently updated my wip website to fuel 1.0.
I updated the following parts of fuel:
fuel/core (the whole directory)
fuel/packages (propably not nessecary)
fuel/app/config
But now the "{exec_time}" and "{mem_usage}" aren't displayed but instead just written out.
In general, the Fuel supplied packages follow the core, so if you update the core, update the packages as well.
The exec_time/mem_usage is now being dealt with in your public/index.php, so you'll have to update that as well.
