It fixes error codes c=74 and c=331 when modifying or printing paychecks.
It also enforces Payment Application Data Security Standards (PA-DSS) which require that merchants accepting credit cards adhere to stricter password protection requirements.
Starting July 1, 2010, merchants processing credit card transactions in QuickBooks must use complex passwords and change them every 90 days. A complex password is one that contains at least 7 characters and has at least 1 number and 1 upper-case letter.
