Below is an Ansible playbook script that performs the following actions sequentially:

1. Retrieves a list of installed packages along with their versions before upgrading.
2. Upgrades the operating system packages.
3. Retrieves a list of installed packages along with their versions after the upgrade to compare which packages were upgraded.

This playbook assumes the target systems are using a Debian-based distribution like Ubuntu, as it utilizes the apt module for package management. Adjustments might be needed for other distributions.
