Version 9.1.0

Release Notes:

  • HTCondor version 9.1.0 released on May 20, 2021.

  • The condor_convert_history command was removed. (HTCONDOR-392)

New Features:

  • Added support for submission to the ARC CE REST interface via the new grid universe type arc. (HTCONDOR-138)

  • Added a new option in DAGMan to put failed jobs on hold and keep them in the queue when DAGMAN_PUT_FAILED_JOBS_ON_HOLD is True.
