Microsoft has now released the Windows 10 ISO files for the latest 20H1 preview build 18932 that is currently being tested by Insiders in the Fast ring. The Windows maker is going to spend almost a year on the development of this particular branch.
The next version slated for an October release will be a non-disruptive cumulative update, which won't be bringing any new features. Following this comes the Windows 10 version 2003 (or the May 2020 Update), which is expected to be a massive upgrade. If you were planning to clean install builds from this version, you can now do that through the freshly released ISO files.

Microsoft has also now started to deliver the preview builds from the Fall 2019 version of Windows 10. Since it won't be a major update, it is only being tested by those in the Slow ring. The company said that 19H2 will be a very small update in comparison to previous versions.
