Right, I did not test _that_ combination. Thanks for taking a look, I
will fix it for the next revision!

One approach here would be to check the server version using the
`/version` endpoint and decide on that. (And re-reading that, Fiona
actually brought up that exact point in the previous thread ..)

FWIW, a (more) future-proof and cleaner compat mechanism could maybe be
to have `/version` also return a list of features supported by the
server, beside the current fields?

E.g.
  {
    "data": {
      "release": "2",
      "repoid": "07151513fa92899c65b1efa47d9b2d40c5dc5d82",
      "version": "2.3",
      "features": ["finish-protected-param"]                 <--
    },
    "success": true
  }

Would something like that be acceptable? Just an idea.
