== User Experience ==
Users will be able to see compiled code improvements and use the newly
added features.
Developers will notice a newer compiler, and might need to adjust
their codebases acording to http://gcc.gnu.org/gcc-9/porting_to.html,
or, if they detect a GCC bug, report it.

FTR only.
Just tested gcc 9.0.0 on one of my projects and seems like gcc 9 is producilng slightly bigger code compare to gcc 8.2.1.
