New features
- Add support for SparkPost
docs - Test with Django 1.10 beta
Other changes
- Requests-based backends (all but SparkPost) now raise
AnymailRequestsAPIError for any requests.RequestException,
for consistency and proper fail_silently behavior.
(The exception will also be a subclass of the original RequestException,
so no changes are required to existing code looking for specific
requests failures.)
