Couple of review items, but this looks good to us. What sort of urgency do you see behind these fixes landing - are they in your opinion show-stoppers for v1.10, or can they be deferred to v2.0?

It's a touch difficult to tell the severity of what's being fixed, though we're leaning toward v1.10 given the docs fixes.

These are very low priority fixes, it can be deferred to v2.0, it should also be very low impact though, as it is in essence just a couple string changes.

LGTM, we'll merge this when the v2.0 cycle starts then.
