Well... something really odd happened with that file, I'm not sure what to say. It somehow reverted to an older one on the server -- I thought I must be crazy, maybe I had made some mistake in uploading it. That would be the most likely thing, right? So I downloaded the offending file, fixed it, and reuploaded it. But the date still said a last updated date of... 8/2... That didn't make any sense at all.
So I downloaded it again, and it was back the way it was before I made the change not a minute or two before. Only having 7052 and 7053 in there, not even 7054, let alone 7055. After that, it moves to Amazon S3, thankfully.
So this time I deleted the existing file first, then did a fresh upload, and it now seems to have taken. I don't know what the deal was. It does show the correct thing here now, no caching, so you should be able to get onto 7.055 and then from there jump to the latest:
