# Upgrade Guide

This document describes breaking changes and how to upgrade. For a complete list of changes including minor and patch releases, please refer to the [changelog](CHANGELOG.md).

## v2

Encodings were factored out from `levelup` into `encoding-down` and in that process they were removed from this module as well. For more information, please check the corresponding `CHANGELOG.md` for:

* [`levelup`](https://github.com/Level/levelup/blob/master/CHANGELOG.md)
* [`encoding-down`](https://github.com/Level/encoding-down/blob/master/CHANGELOG.md)

If your code relies on `options.decoder` for decoding keys and values you need to handle this yourself, e.g. by a transform stream or similar.

Support for node 0.10, 0.12 and iojs was also dropped.
