In addition to these, Beta 3 landed a number of small consistency and polish changes to the REST API, including an improvement to the permissions check used when editing comments, a fix for post type controller caching edge cases, and most importantly, the ability to use the _embed parameter to access the full data for a post using the /wp/v2/search endpoint.
