I see a section in News.md for what has changed here, but I have scripts failing since WORD\_SIZE is no longer defined. What is the replacement we should be using? Thanks.

`Sys.WORD_SIZE`? This change was actually introduced in Julia 0.5:  
[https://github.com/JuliaLang/julia/blob/3c9d75391c72d7c32eea75ff187ce77b2d5effc8/NEWS.md](https://github.com/JuliaLang/julia/blob/3c9d75391c72d7c32eea75ff187ce77b2d5effc8/NEWS.md)

I just ran across this, and also didn’t know how to proceed. The current deprecation warning on v0.5 doesn’t indicate the replacement:

```julia
julia> WORD_SIZE
WARNING: Base.WORD_SIZE is deprecated.
  likely near no file:0
64

```

and NEWS.md doesn’t mention `WORD_SIZE` explicitly.

(NEWS.md does actually mention `WORD_SIZE` explicitly… whoops!)
