[0.7.0](https://github.com/duecredit/duecredit/tree/0.7.0) (2019-03-01)
- Prevent warnings from the injector's `__del__`.
- InactiveDueCollector in `stub.py` now provides also `active=False`
attribute (so external tools could directly query if duecredit is
active) and no-op `activate` and `dump` for consistent API with a
`due` object whenever `duecredit` is available.
- Provide `Text` citation entry for free form text. It does not have any
meaningful rendering in BibTex but is present in text rendering.
`Url` entry also acquired text rendering with prefix `URL: `.
