Do you plan to support salt 2018 for the proxy ?
when trying to install rubygem-smart_proxy_salt on my salt-master I get:
Installed: salt-2018.3.0-1.el7.noarch (@saltstack)
salt = 2018.3.0-1.el7
Available: salt-2015.5.10-2.el7.noarch (epel)
salt = 2015.5.10-2.el7
Do you plan to support the latest version of salt anytime soon ?
