v1.0.0

• Add safe retrying for requests where possible:
  • Automatically retry requests that fail due to network or GoCardless errors.
  • Automatically add an idempotency key for POST requests if not provided manually
  • Breaking change: Automatically retrieve and return the existing resource in the event of a 409 idempotent_creation_conflict response. This changes previous behaviour - instead of seeing an exception at this point, the client will now automatically retrieve the original resource that was created with that idempotency key.
• Support the new verification_status attribute in the Creditors API, which may be either action_required, in_review or successful. See the new "Helping your users get verified" section in the partner guide for details.
• Add GoCardless-Client-Library and GoCardless-Client-Version headers to aid identification of requests
• Add support for Python 3.5 and Python 3.6
