Two Chrome releases this week address at least eight security vulnerabilities and other bugs.
The release notes for Chrome 80.0.3987.162 provide details for some of the security vulnerabilities. A usual, Google holds off publishing vulnerability details until most installs have been updated.
Chrome 80.0.3987.163 appears to roll back a bug fix that was addressed in an earlier version.
You can trust Google to update your installation of Chrome, or do it youself, by navigating its three-vertical-dots menu to
About Google Chrome. This will trigger a check for updates, and if a newer version is available, you should see an Update button or link.
