Release updates from the Chrome team

Stable Channel Update for Desktop

Monday, November 15, 2021

The Chrome team is delighted to announce the promotion of Chrome 96 to the
stable channel for Windows, Mac and Linux. Chrome 96 is also promoted to our
new extended stable channel for Windows and Mac. This will roll out over the
coming days/weeks.

Chrome 96.0.4664.45 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 96.

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

of fixes:

  o [1269629] 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.
