The "newer mirrors" seem a bit mixed up. So it would not help to use them. For the RM680/N950 repo they contain newer versions (as they were used for RM696/N9).
Similar/another issue I have with the N900 repo. There the 'apt' package has the same version number but another build date (see still-to-be-created other thread).
--edit
I just found out that the 'newer' apt packages resides in repository.maemo.org!
downloads.maemo.nokia.com got higher priority by HAM, so always the older (already installed) package was referenced. But now the mirrors have lesser priority, so the package 'apt' and all others are first referenced from repo.maemo.org.
Not a big deal as they should be same. But in this case the apt from maemo.org has indeed the same version number but a higher higher/newer build date. Else they are the same.
I have no idea why and how ?

Another package different is apt-transport-https ...

So for this fmg would need to do some re-coding (to use the latest versions) or we fix the repo mirrors or just use local verions of said debs. They are too big in size to be attached here ...
