CentOS 7 (through and including 7.1) offered the
Applications | System Tools | Software Update
applet. This applet allowed users to update CentOS 7.
Where is the applet in 7.2 v1511? I do not see that anymore.
Yes, I know of
yum -y update. I executed the
yum -y update command, which is how I got from CentOS 7 to CentOS 7 (7.2 v1511).
