Patch dates and build dates are rarely the same. Normally the client was built a day or 2 before the patch day so they can verify everything before pushing it out with the patch. In this case, the client was built on Dec 10th, but the patch didn't hit until Dec 12th:

So the 12/12/12 thread is actually accurate as far as what the ShowEQ people care about, which is patch day itself.
And, it isn't the words that get 90% of your threads deleted, it is the context in which you use them.
I have already verified most of the opcodes in that thread that are dated 12/12/12 are accurate for the Steam RoF client. I also have a good chunk of the opcodes figured out already and should be ready to begin testing them pretty soon. The hard part is going to be that variable length player profile though I think.
