Jira enterprise release 8.5 was released at the end of October 2019. Looking forward to have new Jira connector compatible with Jira 8.5. Can't upgrade our Jira unless it's released.
Support of Jira Software Data Center is required as well.
Concerning the function of the Jira connector, we are not aware of any differences between on-premise Server and Data center editions.
There are currently no plans to introduce support for any Data Center specific capabilities.
As long as this situation remains unchanged, we consider the Jira Connector to be fully applicable to all on-prem editions in the same way.
