Chrome 90.0.4430.85: Google Chrome is up to date

One of the updates in this version of Chrome is for the zero‑day vulnerability. This is said to have been rushed out by Google as several active malicious developers are trying to exploit the vulnerability.

You will see the update roll out automatically to your browser window in the top right corner where it will say “Update.” However, you may also download the update, which is wonderful for those looking for an offline installer, if you like.

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.

This update includes 7 security fixes. Below, we highlight fixes that were contributed by external researchers. Please see the Chrome Security Page for more information.
