Thanks, I’m excited to test drive Julia v1.4!

The first thing I did in Julia v1.4 was add the package [MLJ.jl](https://github.com/alan-turing-institute/MLJ.jl/releases).  
Julia installed `MLJ v0.2.3` instead of the latest version `MLJ v0.10.1`.

Is there some kind of testing that can be done before a new version of Julia is released to check that, say, the top 20 Julia packages (by github stars) work? And the maintainers can be notified pre-release if there is an issue?

Update: I ran `rm -rf ~/.julia` , opened Julia & `Pkg.add("MLJ")` now installed the latest.  
That said, it could be nice to test the most frequently used Julia packages before a release…
