Hello Guys.
Hope you all are safe..!!

I am a bit confused to release the updates on monthly basis, what is the difference between these highlighted updates ?
Let's assume I have released the following update from my WSUS servers 
Do I need to release these below updates too?
Windows 10 Version 1909 for x64-based Systems
Windows 10 Version 1809 for x64-based Systems
Regards,
Ram
