I like to put more then just the link but the actually link so if others can’t get to the site at least they can get the download right away for both x86 and x64 O/S. Also the direct link seems to avoid the doubleclick ads feature but I am not sure but I did notice it when you do go to the site and try to download the file from there???

Found in the forums there, looks like the plan is for a non-beta at the end of October ( THREE CHEERS! ).

Also note: for 9.17, it is suggested to test ZIP archives

Not sure if that means “this beta is risky”, or “this is moving toward release candidate”
