Does anybody know if the Change Group Security Settings plugin works in 16.1?

For the most part many old plugins still work in more recent version of Appian. However that is not something I can guarantee, so I would recommend testing it in your environment thoroughly, and only promoting it to higher environments once you confirm through testing that it doesn't cause any issues.

@mathieud - I agree with ishita. But as the plugin is working on Groups and as per my understanding there has not been major changes in Groups since many previous versions, plugin should work fine on 16.1

@mathieud I believe we used the same plugin on 7.11 and there weren't any issues. What you can do quickly is, inspect the code of the plugin and check if any of the contents are deprecated by taking a look at the release notes of Appian which actually lists deprecated contents as well. That way we can ensure that the plugin will work perfectly.
