 * Added clarification that `id` field values SHOULD always be strings to context schema definition (a restriction that can't easily be represented in the generated types). ([#1149](https://github.com/finos/FDC3/pull/1149))
 * Added requirement that Standard versions SHOULD avoid the use unions in context and API definitions wherever possible as these can be hard to replicate and MUST avoid unions of primitive types as these can be impossible to replicate in other languages. ([#120](https://github.com/finos/FDC3/pull/1200))
+* Added `addEventListener` to the `DesktopAgent` API to provide support for event listener for non-context and non-intent events, including a `userChannelChanged` event ([#1207](https://github.com/finos/FDC3/pull/1207))
+* Added an `async` `addEventListener` function to the `PrivateChannel` API to replace the deprecated, synchronous `onAddContextListener`, `onUnsubscribe` and `onDisconnect` functions and to keep consistency with the DesktopAgent API. ([#1305](https://github.com/finos/FDC3/pull/1305))
 * Added reference materials and supported platforms information for FDC3 in .NET via the [finos/fdc3-dotnet](https://github.com/finos/fdc3-dotnet) project. ([#1108](https://github.com/finos/FDC3/pull/1108))
 * Specifications for getAgent() and Browser-Resident Desktop Agents.
 * Specification for Preload Desktop Agents. This content was previously in the supported platforms section. It had been revised and amended to include recommended behavior related to the new validateAppIdentity() function.

 ### Changed
 
+* `Listener.unsubscribe()` was made async (the return type was changed from `void` to `Promise<void>`) for consistency with the rest of the API. ([#1305](https://github.com/finos/FDC3/pull/1305))
+* Added reference materials and supported platforms information for FDC3 in .NET via the [finos/fdc3-dotnet](https://github.com/finos/fdc3-dotnet) project. ([#1108](https://github.com/finos/FDC3/pull/1108))
 * The supported platforms page in the FDC3 documentation was moved into the API section as the information it provides all relates to FDC3 Desktop Agent API implementations. ([#1108](https://github.com/finos/FDC3/pull/1108))
 * FDC3 apps are now encouraged to instantiate their FDC3 interface (DesktopAgent) using the `getAgent()` function provided by the `@finos/fdc3` module. This will allow apps to interoperate in either traditional Preload DAs (i.e. Electron) as well as the new Browser-Resident DAs.
 
 ### Deprecated
 
 * Made `IntentMetadata.displayName` optional as it is deprecated. ([#1280](https://github.com/finos/FDC3/pull/1280))
+* Deprecated `PrivateChannel`'s synchronous `onAddContextListener`, `onUnsubscribe` and `onDisconnect` functions in favour of an `async` `addEventListener` function consistent with the one added to `DesktopAgent` in #1207. ([#1305](https://github.com/finos/FDC3/pull/1305))

+
+Type defining the format of events representing a context listener being added to the channel (`addContextListener`). Desktop Agents MUST fire this event for each invocation of `addContextListener` on the channel, including those that occurred before this handler was registered (to prevent race conditions).
+
+The context type of the listener added is provided as `details.contextType`, which will be `null` if all event types are being listened to.
+
+### `PrivateChannelUnsubscribeEvent`
+
+```ts
+interface PrivateChannelUnsubscribeEvent extends PrivateChannelEvent {

+  readonly details: {
+    contextType: string | null
+  };
+}
+```
+
+Type defining the format of events representing a context listener removed from the channel (`Listener.unsubscribe()`). Desktop Agents MUST call this when `disconnect()` is called by the other party, for each listener that they had added.
+
+The context type of the  listener removed is provided as `details.contextType`, which will be `null` if all event types were being listened to.
+
+### `PrivateChannelDisconnectEvent`
+
+```ts
+export interface PrivateChannelDisconnectEvent extends PrivateChannelEvent {
+  readonly type: "disconnect";
+  readonly details: null | undefined;
+}
+```
+
+Type defining the format of events representing a remote app being terminated or is otherwise disconnecting from the PrivateChannel. This event is fired in addition to unsubscribe events that will also be fired for any context listeners the disconnecting app had added.
+
+No details are provided.
