</ul>
<li>Possibility to define the list worker directly in the
xrootd config file (new directive xpd.worker, see Wiki reference pages)</li>
<li>Improvements:</li> <li>Support for automatic reconnections in the case xrootd
is restarted</li>
<li>Dedicated admin area (under <span style="font-style: italic;">xrd.admin</span>/.xproof.<span style="font-style: italic;">port</span>) to
keep information about active and terminated sessions, and active
clients. This is used to reguraly check the client and session
activity, to cleanup orphalin sessions and to shutdown inactive client
connections.&nbsp;</li>

<li>Log sending</li>
<ul>
<li> <li>
set the default number of displayed lines to 100 instead of 10</li> Implement selective sending of logs from workers to master to avoid duplicating
too many text lines on the master log. Logs are now sent only after Exec, Print
requests and in case an error (level &gt;= kError) occured. Of course, the full
logs can always be retrieved via TProofMgr::GetSessionLogs
