Microsoft has begun to distribute an update to the operating system for Xbox consoles for insiders, which will allow in the future to update some OS components without completely interfering with the build. A significant change in the firmware update system will allow you to change the shell, settings and other elements of the OS immediately when ready, without waiting for a fresh build.
Therefore, new updates are likely to become smaller, but will be released much more often.
The update system change for all Xbox console users will likely have to wait a little longer. In addition, Microsoft has not yet officially announced the upcoming changes.
