Stable Channel Update for Desktop
Tuesday, August 31, 2021
The Chrome team is delighted to announce the promotion of Chrome 93 to
the stable channel for Windows, Mac and Linux. This will roll out over
the coming days/weeks.


Chrome 93.0.4577.63 contains a number of fixes and improvements -- a
list of changes is available in the log. Watch out for upcoming Chrome
and Chromium blog posts about new features and big efforts delivered in
93.


Security Fixes and Rewards

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