Hi Walker,
We use Redmine version 1.0.1, which contains an issue REST API by default I believe. Therefore is the WS-API plugin still required as specified in your requirements documentation?
Yes it is still required.
Is version 1.0.x of Redmine actually supported or is the integration still linked to the 0.9.x series?
3.1.2 is still limited to Redmine 0.9. The 3.2 release is currently building as I write this, and it will be available for download in the next hours. This release will contain support for Redmine 1.0 and above. User of Redmine 0.8 or 0.9 have to stick with Klaros 3.1 as these older versions will no longer be supported.
By the way, the documentation you provide is really quite good. I know what a thankless job documentation can be so I commend you on doing such a fine job.
Thanks for the kind words, this is much appreciated

Regards,
Torsten
