--- major_changes: - yum and dnf modules now at feature parity - new yum action plugin enables the yum module to work with both yum3 and dnf-based yum4 by detecting the backend package manager and routing commands through the correct Ansible module for that python API - New yumdnf module defines the shared argument specification for both yum and dnf modules and provides an entry point to share code when applicable minor_changes: - Fixed group actions in check mode to report correct changed state - Better error handling for depsolve and transaction errors in DNF - Fixed group action idempotent transactions in dnf backend - Add use_backend to yum module/action plugin - Fix dnf handling of autoremove to be compatible with yum - Enable installroot tests for yum4(dnf) integration testing, dnf backend now supports that - Switch from zip to bc for certain package install/remove test cases in yum integration tests. The dnf depsolver downgrades python when you uninstall zip which alters the test environment and we have no control over that.
