Stable Channel Update for Desktop
Tuesday, November 17, 2020
The Chrome team is delighted to announce the promotion of Chrome 87 to the
Stable channel for Windows, Mac and Linux.
This will roll out over the coming days/weeks.
Chrome 87.0.4280.66 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 87.
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 havent yet fixed.
This update includes 33 security fixes. Below, we highlight fixes that were
contributed by external researchers.
Please see the Chrome Security Page for more information.

We would also like to thank all security researchers that worked with us
during the development cycle to prevent security bugs from ever reaching
the stable channel.
As usual, our ongoing internal security work was responsible for a wide
range of fixes:
[1149434] Various fixes from internal audits, fuzzing and other initiatives
Many of our security bugs are detected using AddressSanitizer,
MemorySanitizer, UndefinedBehaviorSanitizer, Control Flow Integrity,
libFuzzer, or AFL.
