community.general/changelogs/fragments/7242-multi-values-for-same-name-in-git-config.yml

minor_changes:
    - "git_config - allow multiple git configs for the same name with the new ``add_mode`` option (https://github.com/ansible-collections/community.general/pull/7260)."
    - "git_config - the ``after`` and ``before`` fields in the ``diff`` of the return value can be a list instead of a string in case more configs with the same key are affected (https://github.com/ansible-collections/community.general/pull/7260)."
    - "git_config - when a value is unset, all configs with the same key are unset (https://github.com/ansible-collections/community.general/pull/7260)."
