Maintenance versions explained

Within the same major version, max 3 minor versions will be in maintenance mode simultaneously. Minor versions are released on a three month schedule. When a minor version enters support mode (EOM), hotfixes can be provided on request. The ability to request hotfixes ends when the minor version reaches EOS, whereafter only limited technical support will be provided.
