Microsoft has already announced a new Windows 10 Mobile build that will be released soon, but the company hasn't provided any other details on timing or the changes that might be part of this version.

And yet, it turns out that the release is near, as the company has just rolled out an update for the Windows Insider app on Windows 10 Mobile.
This particular application is being used by Microsoft to deliver new Windows 10 Mobile builds, so the update that was released today could be a sign that another version of the operating system is very close to being shipped.
Gabe Aul, head of the Windows Insider program, has already confirmed that they found a bug in Windows 10 Mobile build 10240 that prevents it from getting released to users, so this update for the Windows Insider app might be developed to prevent any other issues from occurring when the new build gets the green light.
Just like all the other app updates, this new version is delivered through the store, so in case your phone is not configured to get it automatically, have a look in the Windows Phone Store and download it as soon as possible to make sure that you can receive the next Windows 10 Mobile build when it's released.

Also, you can manually download the Windows Insider app for Windows 10 Mobile and get all improvements in a second.
