If you use Google Chrome, you’re going to want to read this.

Google Chrome users, listen up. If you are using browser version 53 or below, you may have some trouble accessing your email in the near future.

Earlier this month, Google published a blog post stating that Gmail will only be fully accessible on Chrome browsers above version 53 because of a new security measure. Starting on February 8, a banner will appear at the top of the screen when affected users log into their account that encourages them to upgrade to the latest version of Chrome (v56 was just released this month).

If you use Windows XP and Windows Vista operating systems, you are most likely to be affected by this change, since v49 was the last version supporting these. Google also encourages those users to update to the most recent operating system that includes updates and security fixes for Google Chrome. Even if you’re not on a Windows OS, but you still have anything under v55, you’ll still want to upgrade to the latest release.

If you continue to use a lower version, Google explained that Gmail will still be able to function on Chrome Browser v53 through the end of 2017, but there are security risks and you won’t be able to access new features. In December 2017, users on v53 and below will only be able to see their Gmail in a basic HTML version.

Normally Google doesn’t publicize when they’re not supporting outdated versions of Chrome, but since it will heavily impact Windows users and pose some security risks, the tech company made the larger announcement. If you are using a version of that will not longer support Gmail, you can upgrade to the latest version of Google Chrome at google.com/chrome.
