Windows 10 version 20H2, October 2020 Update, is a small update that introduces many enhancements for existing features, such as a new fresh look for the Start menu, the ability to change the refresh rate within the Settings, deeper integration with Microsoft Edge, and more.
You are not getting new significant features this time around, but this new version of Windows 10 includes many small changes that should improve the work introduced with version 2004.
