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:

   o [1491268] 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.
