In December 2011 the Bureau took over the regulation and published all new forms, which are supposed to be in use starting 1/1/2013.
In November 2012, the Bureau changed four of the forms (those in appendices I, K, M and N) to make some corrections. In doing so, they said that if you had already changed over to the December 2011 forms, you can continue to use what you have until further notice (expected sometime in 2013). But if you haven't yet made the change, you need to use the November 2012 versions of the forms in appendices I, K, M and N when you do make the change, on or before 1/1/13.
Not all of the forms are applicable to lenders. Some have to be used by credit bureaus. Some by employers, etc.
