### Bugfixes
- when using MongoDB as a source with tailing enabled and namespace filtering, it was possible for documents
from others collections to be sent down the pipeline, fixed via [#386](https://github.com/compose/transporter/pull/386)
- if transporter lost connection to MongoDB while tailing the oplog, the connection never successfully reconnected, fixed via [#398](https://github.com/compose/transporter/pull/398)
