In short:

   * all the worker nodes have been upgraded to SL5
   * the old SL4 UI on *t3ui01* stays the same, so that people can work with the old CMSSW releases and submit with CRAB. *CRAB version for SLC4 builds is: /swshare/CRAB/CRAB*
   * a *new SL5 UI t3ui02* has been installed on a virtual machine: It can be used to work with the new SL5 CMSSW releases.
      * Since CRAB is not yet compatible with the new SL5 glite-3.2 grid software release, the node uses a special glite-3.1 environment which will allow you to work with CRAB, but which may expose problems if you use standard grid commands. This is a temporary solution until CRAB is fully compliant with the new glite releases. *CRAB version for SLC5 builds is* <pre>/swshare/CRAB/CRAB_2_6_6</pre>
