Yes its on the Fast ring, I downloaded it last night.
Other than changing the look of the login screen a bit, its mainly just a release filled with a load of fixes.
Thanks Skeeter... but do you mean you downloaded a whole new ISO file, or just a small update?
It is just that I can't see anywhere to actually 'force' it to download a file.
I have the Preview option, and 'fast' selected, and obviously automatic upgrades, but still can't see a 'download' option... unless of course it is hidden somewhere in the Developers section?
