Today we have released a new version of Project Configurator: 1.3.4. This is the first version designed to be compatible with a JIRA Data Center cluster.
Our tests showed that previous versions did export and load correctly configurations in a clustered environment. However, some caches in nodes different to the node where the load had been executed were not updated with the new configuration, so users would be seeing stale information. This problem has been fixed with version 1.3.4.
Thanks to everybody who is using or evaluating Project Configurator! Enjoy the summer!
