Hello, I tough that the functionality that the package `Missings.jl` currently provides for Julia 0.6 (the `Missing` type in substitution of `NA` from older `DataFrames` packages) would be in core starting from Julia 0.7/1.x, and I was going to suggest to the package maintainers to clarify that in the package title/readme (i.e. “Missing value support for Julia 0.6”), but then I found bug reports that refer to “Missings.jl” for julia 0.7, and I am now a bit lost.
In Julia \>=0.7, other packages that use Unions with the `Missing` type, would still they need to add/use the `Missings.jl` package, or not ?

The link just points to the main github page, it is unclear which issue you mean.
But regarding the question: while the type `Missing` will be in Julia v0.7, the Missings.jl package has extra convenience functions. If you look at the [source](https://github.com/JuliaData/Missings.jl/blob/master/src/Missings.jl), you will see that almost everything else is (will not be) not executed on v0.7.

Thank you, I got it. The type is in core, and the separate package remains for the few additional functionalities, so most other packages will NOT need to use the package `Missings.jl`, unless they specifically use the added functionality.
I think it would be useful to specify it in the readme.
(I removed the link, my question wasn’t specific to it)

I think this should be worth opening an issue.

Done (although my English is so-so…):
