Microsoft has released the monthly cumulative update for its latest Windows 10 version 2004, or the May 2020 Update. This latest version has so far already received two cumulative updates, however, there is quite a long list of known issues that is yet to be addressed.

This is the first batch of optional non-security updates that the Windows maker is releasing after it paused these updates back in March as the lockdowns started to be enforced globally. After that the company was only focusing on security fixes.
