Today I made a test with my settings below just to try if there is a new preview build for download available.

 

The result of the search you see in the second window but in the end if I tried to download the following error appears on screen 0x80246017. Micorsoft employees told in different blogs that we have to change reg settings to be able to download new fbl_releases.

 

So then I changed the settings to
Computer\HKEYLOCALMACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability
    BranchName = fbl_release
    ThresholdRiskLevel = low
    ThresholdInternal = should not exist =
    ThresholdOptedIn = should not exist =

but the result with these setting did not show me any preview build available. Till now I tried different settings for these  4 reg keys without any positive result.

So people hang out there is a new build with fbl_awesome1501 available but it seems not to be official.

for those maybe who wanna stay up to date of listing new builds you can use the  link below i found:
