This implies adding a version field to the returned ticket attributes, and then expecting the same marker to be included in the attributes returned for updating. Should be an easy fix.
2 things come to mind:
'version' is already taken by the ticket 'version' field, so I need some other naming. It would need to be something like _version or _ver. I kind of like _ver because it is sufficiently different.
We'll likely need to support updates without the marker for a while. I'll update the docs to strongly recommend against not including it, and then remove old-style update along with some other deprecated changes when releasing a 1.1 version or something.
