    As of release 16.12, the [OpenSocial gadgets](https://en.wikipedia.org/wiki/OpenSocial) was deprecated. This feature is now removed because of a couple of reasons —
      (a) there's not enough evidence of many users using this feature in a way that'll impact their usage of GoCD
      (b) the underlying implementation framework ([Apache Shindig](https://shindig.apache.org/)) hasn't been maintained for quite some time and contain several security vulnerabilities.

    As of release 16.12, version 2 and version 3 of the <%= link_to_api 'agents', 'Agents API' %> was deprecated. Version 2 of Agents API was introduced in 15.3.0 and version 3 of the API was introduced in 16.8. These versions of the API have been removed in favor of version 4 of this API. This api is backward compatible, and users are encouraged to use it.
