 * Added support for event listening outside of intent or context listnener. Added new function `addEventListener`, type `EventHandler`,  enum `FDC3EventType` and interfaces `FDC3Event` and `FDC3ChannelChangedEvent`. ([#1207](https://github.com/finos/FDC3/pull/1207))
 * Added new `CreateOrUpdateProfile` intent. ([#1359](https://github.com/finos/FDC3/pull/1359))
 * Added conformance tests into the FDC3 API documentation in the current version and backported into 2.0 and 2.1. Removed outdated 1.2 conformance tests (which are preserved in the older 2.0 and 2.1 versions). ([#1417](https://github.com/finos/FDC3/pull/1417)).

 In addition to intent and context events, the FDC3 API and PrivateChannel API may be used to listen for other types of events via their `addEventListener()` functions.
 
 ## `ApiEvent`
 
 Type defining a basic event object that may be emitted by an FDC3 API interface such as DesktopAgent or PrivateChannel. There are more specific event types defined for each interface.
