    1414The rest of this document will describe how the notification system will work.
     15
     16== Notification Flag Supported ==
     17Clients that support the BOINC Notification System should include the following flag in the scheduler request:
     18{{{
     19<notifications_supported />
     20}}}
     21
     22When the BOINC Server scheduler sees this flag it’ll include extra information in the scheduler reply that is to be included in the BOINC Client Feed stream.
     23
     24== BOINC Client Feed Stream ==
     25The BOINC Client feed stream is a special in memory RSS feed the BOINC Client software maintains for various user interface components.
     26
     27BOINC Server scheduler replies can add items to the feed stream as well as the client itself.
    1528
    1629== Feed ==
    … …  
    2639 * A whole forum to answer questions or to deal with problems as they arise.

    … …  
    3651|| auth || <null> || Authenticator of the volunteer requesting the feed data. NOTE: For private feeds no information should be provided without the full authenticator. Weak authenticators should be treated as though no authenticator has been provided.||
    3752|| last_guid || <null> || The last guid received by the client.||
