As I said, eventually it will replace the first upload and I guess eventually was yesterday.
I don't think so. It seems that HOBBES is having a problem where multiple copies of the same file cause the newest file to be deleted. The latest should be dated July 5, but the one that is at HOBBES is dated June 14. I am pretty sure that that is the bad one.
I am going to update the WPI, and the ZIP, file with the July 5 files. To do that, I need to change the names, so I will add "2", just before the dot. This will probably change the upload dates too.
Note, that the correct WPI files are at
ftp://ftp.netlabs.org/incoming/mozilla/. That repository is becomming a terrible mess, so watch the dates, carefully. I suppose that the ZIP files should be there too.
