When I do the following in Julia 0.5.2 I have no warnings:

```julia
using MAT
file = matopen("file.mat") 
dict = read(file)

```

but when I change to Julia 0.6.0 I get the warning:

```julia
WARNING: Compat.ASCIIString is deprecated, use String instead.
  likely near In[1]:3 

```

I get the warning from `read(file)`.  
Shall I include Matlab files in some other way using Julia 0.6.0? Or is this just a warning I should ignore?

This is a deprecation warning, which you can ignore. Looks like it was [fixed](https://github.com/JuliaIO/MAT.jl/commit/109f70ba98cc068efc1f7ca5f45aa771f2fd3acd) recently anyway, and should show up in the next release.
