Sometimes when Google releases a new version of Chrome, the release announcement doesn’t mention any security fixes. That’s intentional:

Note: Access to bug details and links may be kept restricted until a majority of users are updated with a fix. We will also retain restrictions if the bug exists in a third party library that other projects similarly depend on, but haven’t yet fixed.

Chrome 80.0.3987.116 was announced on February 18, but the initial announcement didn’t include any mention of five security vulnerabilities that were fixed in that version. Those details were added a few days later.

Three of the vulnerabilities addressed in Chrome 80.0.3987.116 were reported to Google by third party security researchers.

To check your current version of Chrome, click its menu button (three vertical dots) and navigate to Help > About Google Chrome. If a newer version is available, you should see a button or link that allows you to install it.
