 This document maintains a list of changes to Slate with each new version. Until `1.0.0` is released, breaking changes will be added as minor version bumps, and non-breaking changes won't be accounted for since the library is moving quickly.

+### `0.21.0` — July 20, 2017
+
+###### BREAKING CHANGES
+
+- **The `Html` serializer now uses `DOMParser` instead of `cheerio`.** Previously, the `Html` serializer used the `cheerio` library for representing elements in the serialization rule logic, but cheerio was a very large dependency. It has been removed, and the native browser `DOMParser` is now used instead. All HTML serialization rules will need to be updated. If you are working with Slate on the server, you can now pass in a custom serializer to the `Html` constructor, using the `parse5` library.
