~~~~~~~~~~~~~~~~~
- Requires rq >= 0.12.0 and rq-scheduler >= 0.8.3 now.
- Fixes imcompatibility with the new rq 0.12.0 release with which the
``flask rq worker`` command would raise an error because of changes
in handling of the ``worker_ttl`` parameter defaults.
- Added support for Python 3.7. Since 'async' is a keyword in Python 3.7,
`RQ(async=True)` has been changed to `RQ(is_async=True)`. The `async`
keyword argument will still work, but raises a `DeprecationWarning`.
- Documentation fixes.
