    manager, as well as various other functions and constants useful for implementing services in
    general.</para>

    <title>Interface stability</title>

    <para>Strict backwards-compatibility is maintained for the API (application programming interface) and
    ABI (application binary interface). Symbol versioning is used, with symbols only added and never removed.
