 With some minimal effort, as the ReactiveMongo people had already done the majority of the work, we felt that adding a base repository class creates a library without some

 * The dependency to HMRC's fork of `reactivemongo` has been dropped in favour of the original `reactivemongo` driver. Version 7.x.x depends now on `reactivemongo` 0.16.0.
 * It got merged with `play-reactivemongo` so all classes which used to be provided by that library are now in `simple-reactivemongo` (for instance `ReactiveMongoHmrcModule` Play module and `ReactiveMongoComponent`). As a consequence `simple-reactivemongo` should be the only dependency a service would require for interactions with `MongoDB`. There will be no new version of `play-reactivemongo` depending on the `simple-reactivemongo` 7.x.x or above.

 It’s no longer an Exception. As it no longer represents errors in the public API, the following properties have been removed: `errmsg`, `hasErrors`, `inError` and `message`.
 
 simple-reactivemongo previously exposed `inError`, something that is no longer possible.
