    • Improved reliability
  • GRAM5

    • Fixed a number of bugs found by OSG during high scalability testing.
    • Added job expiration and automatic cleanup for jobs that finish, but client does not do a final commit for several hours. This is configurable via RSL. Improves use of Condor-G for OSG.
