Add Compat entry for KERNEL

 * `repeat` now accepts any `AbstractArray` [#14082](https://github.com/JuliaLang/julia/pull/14082): `Compat.repeat` supports this new API on Julia 0.3 and 0.4, and calls `Base.repeat` on 0.5.
 
+* `OS_NAME` is now `Sys.KERNEL`. OS information available as `is_apple`, `is_bsd`, `is_linux`, `is_unix`, and `is_windows`. [16219](https://github.com/JuliaLang/julia/pull/16219)

 ## New types
 
 * [`Nullable` types](http://julia.readthedocs.org/en/latest/manual/types/?highlight=nullable#nullable-types-representing-missing-values) and their associated operations.
