Hello,

I have a simple jump model and it’s running. When I try to check the solution using solution\_summary, it gives me an error:  
`UndefVarError: solution_summary not defined`

Any idea why this is bugging?  
I’m using Julia 1.5.3 and JuMP v0.21.4

Here is my simplified code:

```julia
using JuMP, GLPK, LinearAlgebra
using Distributions

p = 0.9
ex0 = Model(GLPK.Optimizer)

@variable(ex0, x >= 0)

μ = 5
vari = 4
ξ = Normal(0, 1)

@objective(ex0, Min, x)
@constraint(ex0, x >= quantile(ξ, p) * sqrt(vari) + μ)

optimize!(ex0)

# To check the results:
solution_summary(ex0)

```

Thanks!

Please update to Julia 1.6 and JuMP 1.0. You’re using an old version, and solution summary was added more recently.
