 ### `0.9.0` — _July 28, 2016_
 
+#### BREAKING CHANGES
+
 - **The `wrap` and `unwrap` method signatures have changed!** Previously, you would pass `type` and `data` as separate parameters, for example: `wrapBlock('code', { src: true })`. This was inconsistent with other transforms, and has been updated such that a single argument of `properties` is passed instead. So that example could now be: `wrapBlock({ type: 'code', { data: { src: true }})`. You can still pass a `type` string as shorthand, which will be the most frequent use case, for example: `wrapBlock('code')`.
 
 
 ### `0.8.0` — _July 27, 2016_
 
+#### BREAKING CHANGES
+
 - **The `onKeyDown` and `onBeforeInput` handlers signatures have changed!** Previously, some Slate handlers had a signature of `(e, state, editor)` and others had a signature of `(e, data, state, editor)`. Now all handlers will be passed a `data` object—which contains Slate-specific data related to the event—even if it is empty. This is helpful for future compatibility where we might need to add data to a handler that previously didn't have any, and is nicer for consistency. The `onKeyDown` handler's new `data` object contains the `key` name, `code` and a series of `is*` properties to make working with hotkeys easier. The `onBeforeInput` handler's new `data` object is empty.
 
 - **The `Utils` export has been removed.** Previously, a `Key` utility and the `findDOMNode` utility were exposed under the `Utils` object. The `Key` has been removed in favor of the `data` object passed to `onKeyDown`. And then `findDOMNode` utility has been upgraded to a top-level named export, so you'll now need to access it via `import { findDOMNode } from 'slate'`.
