I don’t know exactly why this happens.

```julia

I see that the latest release of [Mux.jl is `v0.5.0`](https://github.com/JuliaWeb/Mux.jl/tags). Thanks for the help.

The new Mux version has not been registered yet: [https://github.com/JuliaLang/METADATA.jl/tree/metadata-v2/Mux](https://github.com/JuliaLang/METADATA.jl/tree/metadata-v2/Mux).

You can do `add Mux#master` to get the master version.
