## Fixes

### Make lists of models and enums work correctly in custom templates

Lists of model and enum classes should be available to custom templates
via the Jinja
variables `openapi.models` and `openapi.enums`, but these were being
passed in a way that made
them always appear empty. This has been fixed so a custom template can
now iterate over them.

Closes #1188.
