This release is the result of the community's work over the past six
months, including: retpoline Spectre variant 2 mitigation,
significantly improved CodeView debug info for Windows, GlobalISel by
default for AArch64 at -O0, improved scheduling on several x86
micro-architectures, Clang defaults to -std=gnu++14 instead of
-std=gnu++98, support for some upcoming C++2a features, improved
optimizations, new compiler warnings, many bug fixes, and more.
Thanks to everyone who helped with filing, fixing, and code-reviewing
for release-blocking bugs!
