Release Notes for NorduGrid ARC 7.1.2

May 18, 2026

This is a bugfix release addressing only a single bug causing migration problems from ARC 6.

The problem was due to wrong permissions set to the new jobs directory that is created in the controldir in ARC 7.

How to fix

1. If you are migrating from ARC 6 to ARC 7, just do the upgrade according to the migration guide
2. If you already have migrated from ARC 6 to ARC 7, you have two options:
   1. Manually change the permission settings on the jobs folder, simplest method:
      chmod -R 0755 /jobs
      
   2. By installing this bugfix release. Example for RHEL:
      1. arcctl service stop -a
      2. dnf update "nordugrid*"
      3. rm /version2
      4. arcctl service restart -a
      

The following Bugzilla ticket has been addressed:

• 4297 Wrong permission of controldir/jobs after upgrade from ARC 6 to ARC 7

Future support of ARC 6-series

Now that ARC 7 is released, we expect one final ARC 6 release, but after that we will only provide security updates of ARC 6. In particular:

1. No new feature development is planned or going on for ARC6 and no bug-fixing development will happen on ARC6 code base in the future except for security issues.
2. Security fixes for ARC6 will be provided till end of March 2026.
3. Production Sites already running ARC 6 will be able to get deployment and configuration troubleshooting help via GGUS Helpdesk till end March 2027. This we call "operational site support".
4. In EPEL ARC packages have their major release number as part of the package name, arc6 and arc7 packages can not be confused.
5. In the Nordugrid repository, you have to specifically enable the ARC 7 repo to get the ARC 7 update. See repository info.
