/*****************************************************************************
 * Backported symbols. Usually, new API is only added in new major versions
 * of NetworkManager (that is, on "master" branch). Sometimes however, we might
 * have to backport some API to an older stable branch. In that case, we backport
 * the symbols with a different version corresponding to the minor API.
 *
 * To allow upgrading from such a extended minor-release, "master" contains these
 * backported symbols too.
 *
 * For example, 1.2.0 added nm_setting_connection_autoconnect_slaves_get_type.
 * This was backported for 1.0.4 as nm_setting_connection_autoconnect_slaves_get_type@libnm_1_0_4
 * To allow an application that was linked against 1.0.4 to seamlessly upgrade to
 * a newer major version, the same symbols is also exposed on "master". Note, that
 * a user can only seamlessly upgrade to a newer major version, that is released
 * *after* 1.0.4 is out. In this example, 1.2.0 was released after 1.4.0, and thus
 * a 1.0.4 user can upgrade to 1.2.0 ABI.
