this version supports the JIRA Server 6.4.14 - 7.2.0. What should I do in order to make the plugin compatible with the 7.4.1 or 7.4.2 version. Will a new SDK be released soon?
The SDK is compatible with 7.4 - you just have to specify the version in the Pom. My guess is that the version range doesn’t get updated since they’re independent dev teams.
Don’t rely on the API being the same when testing minor version changes. It’s a good first step but the functionality underneath may change (integration tests are really important).
