Release Schedule

Name Version Development Freeze Package Freeze Release Notes
November 3.4.5, 3.3.30 2017-10-30 2017-11-06 2017-11-14 5 week cycle
December 3.4.6, 3.3.31 2017-11-27 2017-12-04 2017-12-12

Notes: Additional “urgent” releases may be scheduled for the 4th Tuesday of each month. The Testing date is when acceptance testing will be scheduled for releasable packages; if a package is added after this date, it may not be possible to schedule adequate testing time, thereby forcing it into the next release.

OSG Software Team

  • Documentation migration remaining items
    • SoftwareTeam migrations
    • Release3 and SoftwareTeam archivals
    • TWiki migration headers and archive doc deletions
  • Globus EOL: Actively discussing repo destination with EGI and WLCG
  • November release development freeze - 11/30

Discussions

  • Per-page migration headers are preferred but a per-web migration would be easier
  • We need to search and replace twiki references in software

Support Update

  • Colorado (BrianL) - BeStMan not accepting RFC-compliant proxies
  • JINR (BrianL) - blahp failures due to some issue with ASCII chars
  • LBNL (BrianL) - issues with the blahp may have been due to misconfiguration
  • Taiwan (BrianL) - idle jobs on CE, likely a basic configuration issue
  • GLOW (Derek, Edgar) - GLOW isn't running on many OSG sites we would expect. Edgar is leading the investigation.
  • CMS / NERSC (Derek) - Add userspace StashCache for CMS data caching. Ongoing.

OSG Release Team

  • Tim Theisen will handle the next release if the new procedure is used
