With the latest build Microsoft also introduced an another ring “Release Preview” for Windows Insiders.
The Release Preview ring will focus on Insiders that want to stay on the Current Branch (currently builds based off of 10586), but continue to receive early access to updates, application updates, and driver updates.
The Windows Insider Program has 4 rings now :
Fast– Best for Insiders who enjoy being the first to get access to builds and feature updates, with some risk to their devices in order to identify issues, and provide suggestions and ideas to make Windows software and devices great.
Slow– Best for Insiders who enjoy getting early access to builds and feature updates, with less risk to their devices, and still want to provide feedback to make Windows software and devices great.
Production ring– allows Windows 10 Mobile users to get the latest firmware and the latest OS for their device depending on their region and carrier.
Release Preview– Best for Insiders who enjoy getting early access to updates for the Current Branch, Microsoft applications, and drivers, with minimal risk to their devices, and still want to provide feedback to make Windows devices great.
