The easiest way to find the changes when you download the ARF documents is to look at the far right side of each line. That's the date of the last update. Not all updates are frequencies of course but it at least gives you a starting point. Look for lines marked 200707 or 200705. Those will be the most recent changes.
The actual frequencies you're concerned with are the primary and secondary AR freqs. Those are the freqs right after the column containing WGE. Yes, there have been several changes. The format of the document makes it difficult to line up the columns with the headings because the format is much wider than a monitor allows - even with a widescreen monitor.
Bottom line: the document is still available, many AR freqs have changed, and you better download it while you still have the opportunity to do so. All of this is going away in the near future.
Dave, thanks for starting this thread to point out these changes.
