Stable Channel Update for Desktop
Wednesday, April 14, 2021
The Chrome team is delighted to announce the promotion of Chrome 90 to the
stable channel for Windows, Mac and Linux. This will roll out over the coming
days/weeks.
Chrome 90.0.4430.72 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 90.
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 37 security fixes. Below, we highlight fixes that were
contributed by external researchers. Please see the Chrome Security Page for
more information.
