I just downloaded julia 0.6 from here:  
[https://s3.amazonaws.com/julialang/bin/osx/x64/0.6/julia-0.6.0-pre.alpha-osx10.7+.dmg3](https://s3.amazonaws.com/julialang/bin/osx/x64/0.6/julia-0.6.0-pre.alpha-osx10.7+.dmg3)

After changing the Juno/Atom path to the new julia, trying ‘2+2’ gives the error:  
UndefVarError: isdebugging not defined

This should be fixed by  
[https://github.com/JunoLab/Atom.jl/commit/4b4d73dea7ad3d9dd183e966091fa4509808cf3c](https://github.com/JunoLab/Atom.jl/commit/4b4d73dea7ad3d9dd183e966091fa4509808cf3c)  
so if you checkout Atom.jl you should be good to go (though the debugger won’t work for now until Gallium is updated).
