Trunk 2081 and new functions

Someone could explain me better this new function ?

1)Allow Piwik archiving to trigger when reports are viewed from the browser (trigger where ? )

2)Reports for today will be processed at most every

The 2nd one it’not the auto refresh of live widget ?

Sorry for my english

Se c’è qualche italiano mi potrebbe anche in pvt spiegare meglio queste due funzioni ?
