 ## 2.0.0
 
-This release upgrades to `abstract-level` 2.0.0 which adds [hooks](https://github.com/Level/abstract-level#hooks) and drops callbacks, not-found errors and support of Node.js < 16. Please refer to the [upgrade guide of `abstract-level`](https://github.com/Level/abstract-level/blob/v2.0.0/UPGRADING.md). The only thing to add is that the additional methods of `classic-level` like `db.approximateSize()` also don't support callbacks anymore.
