RE: What to expect from OSG 3.4

On May 30, we sent an e-mail outlining many of the changes to expect in OSG 3.4 and since then, we have released OSG 3.4.0 (details can be found here: https://twiki.opensciencegrid.org/bin/view/Documentation/Release3/Release340 ) and added relevant documentation. Most prominently, documentation is now available for installation and configuration of the LCMAPS VOMS plugin (https://twiki.opensciencegrid.org/bin/view/Documentation/Release3/InstallLcmapsVoms), including instructions to transition from edg-mkgridmap. Additionally, we have released our retirement policy and timelines for the following software:

  - GUMS (https://opensciencegrid.github.io/technology/policy/gums-retire/)
  - BeStMan (https://opensciencegrid.github.io/technology/policy/bestman2-retire/)
  - VOMS Admin Server (https://opensciencegrid.github.io/technology/policy/voms-admin-retire/)

As always, if there are any questions or concerns, please contact us at goc@opensciencegrid.org

Future support dates for OSG 3.3 sites

After last week's release of OSG 3.4.0, the software and release teams will begin the end-of-life process for the OSG 3.3 branch. This means that we will provide regular support to software in the OSG 3.3 stack until December 2017, and critical bug and security fixes until May 2018. The relevant text can be found below or at our release series support policy page (https://opensciencegrid.github.io/technology/policy/release-series/).

OSG supports at most two concurrent release series, current and previous, where the goal is to begin a new release series about every 18 months. Once a new series starts, OSG will support the previous series for at least 12 months and will announce its end-of-life date at least 6 months in advance. During the first 6 months of a series, OSG will endeavor to apply backward-compatible changes to the previous series as well; afterward, OSG will apply only critical bug and security fixes. When support ends for a release series, it means that OSG no longer updates the software, fixes issues, or troubleshoots installations for releases within the series. The plan is to maintain interoperability between supported series, but there is no guarantee that unsupported series will continue to function in OSG.
