Before it used to return an Array. I wonder what is the reason for this change ?

Do we have to do something in our existing codes to account for this change ?

The return type hasn’t changed, this was purely a printing change. `Matrix{T}` is just an alias for `Array{T, 2}`.

You can see what Simeon says for yourself:

```julia
julia> Matrix{Float64} == Array{Float64, 2}
true

```

the same holds for

```julia
julia> Vector{Float64} == Array{Float64, 1}
true

```

Actually, since version 1.6 Julia explicitly tells you that `Matrix` is just an alias:

```julia
julia> Matrix{Float64}
Matrix{Float64} (alias for Array{Float64, 2})

```
