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:

      [1520680] 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.
