We have stopped sending out new work units on UD today. Instead, we have sent a null work unit that sleeps and displays a message indicating how to find instructions for upgrading to the Boinc software. Over the next few weeks we will still be waiting for the remaining work units to finish under UD and send their results to the servers. If we don't get all of them back that we need, we will use Boinc to finish those. Thank you for you all of your contributions via the UD agent. We hope to see you continue contributing using Boinc.
