the coming days/weeks.

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 22 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:

[762099] 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.

 Interested in switching release channels? Find out how.  If you find a
new issue, please let us know by filing a bug. The community help forum
is also a great place to reach out for help or learn about common
issues.
