This is just a general announcement to let folks using the check/money order, COD, or 'other' payment methods in production sites know that these payment methods, their code, and menu items have been put into a new core module. You will have to enable the "Payment Method Pack" module to keep using them on your site, but that's it. This is as of Bazaar revision 777 and will be in beta 3 as the beta-do list keeps getting smaller.

Please report any issues related to this move in this thread.
