  <p>This document describes the changes made to the Megaco system
    from version to version. The intention of this document is to
    list all incompatibilities as well as all enhancements and
    bugfixes for every release of Megaco. Each release of Megaco
    thus constitutes one section in this document. The title of each
    section is the version number of Megaco.</p>

          <p>Callbacks, when the callback module is unknown (undefined),

          <p>A race condition scenario. As part of a cancelation operation,
            replies with waiting acknowledgements is cancelled. This includes
            informing the user (via a call to the handle_trans_ack callback 
            function). It is possible that at this point the connection data 
            has been removed, which makes it impossible for megaco to 
            perform this operation, resulting in the warning message. The 
            solution is to also store the callback module with the other 
            reply information, to be used when cleaning up after a 
            cancelation. </p>

          <p>Improve handling of async transaction reply. </p>
          <p>For asynchronous requests, issued using 
            <seealso marker="megaco#cast">megaco:cast/3</seealso>, 
            the reply will be delivered using the 
            <seealso marker="megaco_user#trans_reply">handle_trans_reply/4,5</seealso> 
            callback function. </p>
          <p>If a receiver of a request, issued using 
            <seealso marker="megaco#cast">megaco:cast/3</seealso>, 
            does not reply in time, megaco re-sends the request. 
            If the receiver of the request sends the reply at the same 
            time as megaco re-sends, it may also send a reply to the 
            resent request (thinking the first reply got lost). These 
            two replies may arrive more or less at the same time, 
            causing confusion. </p>
          <p>In order to improve this situation, a number of 
            improvements have been done: </p>
          <list type="bulleted">
            <item>
              <p>When the first reply arrives, a timer, request-keep-alive, 
                is started. This timer is used to decide when to stop 
                accepting replies as legitimate. </p>
              <p>The timeout time for the timer is specified by the
                config option <em>request_keep_alive_timout</em>, 
                which can be set per 
                <seealso marker="megaco#ui_request_keep_alive_timeout">user</seealso> 
                or per 
                <seealso marker="megaco#ci_request_keep_alive_timeout">connection</seealso>. </p>
	    </item>
            <item>
              <p>We also keep track of how many replies has been received
                (we do this as long as the request-keep-alive timer is 
                running). </p>
            </item>
            <item>
              <p>Each reply that arrives while the request-keep-alive timer 
                is running (including the first) will be delivered using the 
                <seealso marker="megaco_user#trans_reply">handle_trans_reply/4,5</seealso> 
                callback function, but with the UserReply augmented to
                include a serial number indicating which reply number this
                is. 
                The <em>first</em> reply to arrive, 
                will be numbered <em>one (1)</em>. </p>
            </item>
            <item>
              <p>Replies arriving after the timer has expired will be delivered
                in the same way as before, using the 
                <seealso marker="megaco_user#unexpected_trans">handle_unexpected_trans/3,4</seealso> 
                callback function. </p>
	     </item>  
            <item>
              <p>Note that if the timer was <em>not</em> configured, 
                megaco will act exactly as before! </p>
