0.4.0
    * drop Python3.6, as SqlAlchemy2.0 is required for tests
    * Additional typing
    * `request.access_token` is now a private `request.access_token_object`,
      which is this package (and integrators') datastore backed object to
      more properly isolate it from the various oAuthlib token instances.
    * Removed deprecated functions:
      * oauth1.validator.OAuth1RequestValidator_Hooks.create_access_token_existing
      * oauth1.validator.OAuth1RequestValidator.create_access_token_existing
      * tests.oauth1_utils.CustomValidator_Hooks.create_access_token_existing
    * require typing_extensions as `Literal` is not in Python3.7
