Once your buyer leaves feedback upon receipt...paypal will release the funds. If the buyer does not leave feedback...the payment is held for 21 days.
You should ship all your items with delivery confirmation. It's your proof the item was received and actually required in the paypal user agreement.
Personally I liked receiving my money immediately but I understand the change. People would get ripped off and there wasn't a balance in the paypal account to retrieve funds in a dispute. Paypal could side in your favor but that didn't necessarily mean you would receive a full refund from them. It's limited to the balance of the account.
