## 2.7.0

* Depends on `persistent-2.10.0` which provides the `OnlyOneUniqueKey` and `AtLeastOneUniqueKey` classes. Automatically generates instances for these classes based on how many unique keys the entity definition gets. This changes requires `UndecidableInstances` to be enabled on each module that generates entity definitions. [#885](https://github.com/yesodweb/persistent/pull/885)
* Removed deprecated `sqlOnlySettings`. Please use `sqlSettings` instead. [#894](https://github.com/yesodweb/persistent/pull/894)
