 * **Sessions:** A new session is tracked by the SDK whenever the containing app is restarted (this refers to a 'cold start', i.e. when the app has not already been in memory prior to being launched) or whenever it becomes active again after having been in the background for 20 seconds or more.
 * **Users:** The SDK anonymously tracks the users of your app by creating a random UUID that is then securely stored. The UUID is securely stored in the preferences of the client app.
 - **Custom Events**: With HockeySDK 4.1.0 you can now track Custom Events in your app, understand user actions and see the aggregates on the HockeyApp portal.
-- **Batching & offline behavior**: The SDK batches up to 50 events or waits for 15s and then persist and send the events, whichever comes first. So for sessions, this might actually mean we send 1 single event per batch. If you are sending Custom Events, it can be 1 session event plus X of your Custom Events (up to 50 events per batch total). In case the device is offline, up to 300 events are stored until the SDK starts to drop new events.
