I honestly don't know. I believe their intent was to say that it's not tested for upgrading previous OS versions, only previous builds.
Neverwind i figured out: "Calling all Insiders: ISO files of the November Update (build 9879) are now available for download. You'll still receive this update automatically via Windows Update, but if you prefer a clean install or you want to install on a virtual machine, you can download an ISO file instead." . So with this new ISO i will get latest Win10 TP build if i do clean install on my laptop (i'm thinking of replace my Win8.1 to Win10 TP as main OS for daily use)
updated the OP and added the direct links. I've verified all the downloads and hashes. They all work. Files would just need a rename if you want MSDN filenames.
ffs MS give me a server too haha If I hear from threat today, Ill see about debug stuff etc. He's been under the weather lately, so dunno if Ill see him before Paul sucks technet dry

Is it possible this same build but official, has fixes over the 9879 build that most downloaded from the "previews build " tab? I am asking because I guess its now in "Slow" preview build update, which means has less bugs then the "Fast" we used to download this build :\ . Or did they just test this build for a month till it official released?
Yesterday Gabe Aul mentioned that they wait upon some feedback traffic seeing if the update for 9879 works fine and then they will release the isos ... which they obviously did
Im guessing the ISOs in the OP are the updated / bug fixed versions that the "slow" channel guys would have got ?
Since the Enterprise MSDN ISOs are the same as Eval Center (which not fixed), i guess the Pro ISOs would be the same
