Another new version of Adobe Reader (aka Adobe Acrobat Reader DC) was released last week. Reader version 2021.005.20048 includes fixes for two security vulnerabilities, both of which were apparently discovered by independent security researchers.
Unless you’ve disabled the function, Reader will update itself shortly after a new version becomes available. I usually find that by the time I become aware of a new version, Reader has already updated itself on my main PC.
You can check Reader’s version by navigating its menu to
