2.2.2 (September 28, 2018)

• When using React.createContext and SSR, we now make sure the context
  provider value is reset to the previous value it had after its children are
  walked.

• Revert:
  When a query failed on the first result, the query result data was being
  returned as undefined. This behavior has been changed so that data is
  returned as an empty object. This makes checking for data (e.g.
  instead of data && data.user you can just check data.user) and
  destructring (e.g. { data: { user } }) easier. Note: this could
  potentially hurt applications that are relying on a falsey check of data
  to see if any query errors have occurred. A better (and supported) way to
  check for errors is to use the result errors property.
