Microsoft released several new Windows Insider builds since the final release of its new Windows 10 operating system a couple of months ago.
The company released patches for Windows 10 RTM as well but those were largely security or stability related and not feature updates.
Sources close to Microsoft indicate that this will change in early November when Microsoft plans to release the Windows 10 Fall Update to the release version of the operating system.
The new update, previously known as Threshold R2 introduces improvements to existing features as well as new features to the operating system.
The update has no prerequisites and can be installed on any Windows 10 RTM version right away as it is cumulative in nature. In addition, it is installed via Windows Update under the name "Windows 10 November 2015".
