If you're a Windows Insider, you probably received an email alerting you that the that the Windows Insider Program Agreement Terms would change this week. The new version of the document is now online on the Windows Insider website, and you can check it on this page.

It's worth noting though that the Confidentialiy/NDA terms have disappeared, which makes sense as Windows 10 Insider builds are public and accessible to everyone.
