The interesting thing is that the FCD is available for a free download, but once the standard is finalized, you will have to pay for the document. Downloading this one now might be a good idea for anyone hoping to keep up with the changes. The document is only 1300 pages, after all. Of course, many others have covered this topic much more than I have. If you haven’t been paying attention to the upcoming changes until now, this is probably the time.
