We’ve recently upgraded to the latest Octopus version, up from 2020.5 and found that the integration with Jira Server is broken for us in the new release.
Looking at the code changes for Jira integration, the reason seems to be that Octopus has switched to using V3 of the Jira REST API, which our server does not support. From scouring the net, it doesn’t seem like Jira Server supports V3 in general.
Reading Atlassian documentation, the API versions have the same endpoints and only differ in support for ADF, which Octopus doesn’t seem to need. Would it be possible to downgrade the API used in Octopus to V2?
Alternatively, is there a possibility of maintaining backwards compatibility (eg by using a switch) to select the version of the API that Octopus should use?
