Automatic events

The SDK sends these without you calling track(). They help you see installs, updates, first open, daily activity, and errors in the dashboard.

Event	When
__first_open	The first time a new anonymous user id is created for this install.
__install	The extension was installed.
__update	The extension was updated; may include previousVersion.
__daily_ping	At most once per UTC day per user after startup.
__error	Automatic error capture, or manual captureError / captureLastError.

Avoid using these names for your own custom events so reports stay easy to read.

See Error tracking for how __error is populated.
