You check the latest version of the as mentioned above using yum check-update and check the version of the installed rpm: rpm -qa | grep mypackage.

Next obtain the a copy of the current rpm and new rpm using yumdownloader (you may need to use sudo as some TLS certs may only be accessible to root) e.g:

sudo yumdownloader mypackage-current.version
sudo yumdownloader mypackage-latest.version

Then install pkgdiff: sudo yum install pkgdiff and run it to generate an HTML report on the differences:

pkgdiff mypackage-current.version mypackage-latest.version

  1. check the changelog

You can check the changelog file:

make sure that you have the package yum-plugin-changelog

and then you can use this command to print the last (most recent) changelog message for the xyz package

# yum changelog 1 xyz | less

otherwise you can use rpm:

# rpm -q --changelog -p xyz-1.0.rpm | less
# rpm -q --changelog -p http://mirror.centos.org/centos/6/os/x86_64/Packages/xyz-1.1.rpm | less
  1. compare the files list

to List Files inside the rpm:

Download xyz-1.1.rpm and list files in xyz-1.1.txt

# rpm -qlp xyz-1.1.rpm > xyz-1.1.txt

then list file of the installed package xyz-1.0.rpm

# rpm -ql xyz > xyz-1.0.txt

and finally:

# diff xyz-1.0.txt xyz-1.1.txt

yum check-update

This command allows you to determine whether any updates are available for your installed packages. yum returns a list of all package updates from all repositories if any are available.
