Hi,

I am a new user of Julia.  
I have the Julia 0.6.2 and JuMP 0.15.1  
However, I would like to update JuMP to version 0.18.0 but I have a problem to do it.  
I received this\>

**julia\> Pkg.update(“JuMP”)**  
**INFO: Updating METADATA…**  
**INFO: Computing changes…**  
**INFO: Package JuMP was set to version 0.15.1, but a higher version 0.18.0 exists.**  
\*\* To install the latest version, you could try doing a full update with `Pkg.update()`.\*\*  
**INFO: No packages to install, update or remove**

And, I did the suggestion:

**julia\> Pkg.free(“JuMP”)**  
**INFO: Freeing JuMP**  
**INFO: Downgrading JuMP: v0.18.0 =\> v0.15.1**

After that, I try to update JuMP but I couldn’t update it:

**julia\> Pkg.update(“JuMP”)**  
**INFO: Updating METADATA…**  
**INFO: Computing changes…**  
**INFO: Package JuMP was set to version 0.15.1, but a higher version 0.18.0 exists.**  
\*\* To install the latest version, you could try doing a full update with `Pkg.update()`.\*\*  
**INFO: No packages to install, update or remove**

Likewise, I noticed with Pkg.status() that JuMP have a Master label. What’s the mean?
