I am trying to migrate to Julia 0.7 and since 0.7 is releases just yesterday, some packages latest release didn’t support 0.7 but already fixed on master.

So I’ve tried to use `Pkg.checkout("XLSX")` but `Checkout` seems deprecated a long ago.

It would be nice to know a way to get a package master in Julia 0.7

Thank you!

Watch the video from juliacon on the new package manager. And [the docs](https://docs.julialang.org/en/stable/stdlib/Pkg/) are quite a good read.

I think you are looking for

```julia
pkg> add XLSX#master

```

So I have to change REPL mode to fetch from the master. Thank you 🙂

In addition to the REPL mode (`pkg> add XLSX#master`) you can use `Pkg.add(PackageSpec(name = "XLSX", rev = "master"))`.
