 ## API
 
 The API of `memory-level` follows that of [`abstract-level`](https://github.com/Level/abstract-level) with a one additional constructor option (see below). The `createIfMissing` and `errorIfExists` options of `abstract-level` are not relevant here. Data is discarded when the last reference to the database is released (i.e. `db = null`). Closing or reopening the database has no effect on the data. Data is _not_ copied: when storing a Buffer value for example, subsequent mutations to that Buffer will affect the stored data too.

+## 3.0.0
+
+This release upgrades to `abstract-level` 3. Please see its [upgrade guide](https://github.com/Level/abstract-level/blob/v3.0.0/UPGRADING.md) (note that `memory-level` already dropped Node.js 16).
+
 ## 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 `memory-level` also drops Node.js 16.
