There's a new setting in your Financial Settings that allows you to turn off the option for your customers to pay for orders with ACH payments. While some companies like to offer that option, there can be risk involved (for example they pay with an e-check which marks the order as paid, so you start building it but then the payment bounces later).
We have retroactively defaulted this setting to "ON" so no action is required on your part to continue accepting ACH payments.
It will be up to you to make the changes if you no longer want to offer ACH payments to some or all customers.
To do this you'll turn this global setting off by going to Settings -> Financial and unchecking the box at the top called "Process eChecks."
