How to add the additional priorities of 8.0 updated Version?

[Jose Estrada]

Hi, I see that I have the new icons of priorities on my updated version of JIRA Server 8.0.2, but according to the Atlassian "What's New" about this topic there should be more priorities added to my default scheme, isn't it? 

I only have from Highest to Lowest, where are the rest? do I have to manually add them, and search for the icons on the web? or are this just suggested priorities?

Thanks
