- Update requirements.
- Use [Travis CI](https://travis-ci.org) for continuous integration. **django-ca** is now tested
with Python 2.7, 3.4, 3.5, 3.6 and nightly, using Django 1.8, 1.9 and 1.10.
- Fix a few test errors for Django 1.8.
- Examples now consistently use 4096 bit certificates.
- Some functionality is now migrated to `cryptography` in the ongoing process to deprecate
pyOpenSSL (which is no longer maintained).
- OCSPView now supports directly passing the public key as bytes. As a consequence, a bad
certificate is now only detected at runtime.
