This build contains a number of bug fixes, security updates, and feature enhancements. A list of changes can be found here. Systems will be receiving updates over the next several days.

Security Fixes:

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