 The event system was redesigned to be easier to use. Instead of relying on the source of the event, it now has a simpler implementation that relies on event targets.
 
-- The `emit` function now emits the event to all event listeners
-- Added a new `emit_to` function to trigger an event to a specific target
+- The `emit` function now emits the event to all event listeners.
+- Added a new `emit_to`/`emitTo` function to trigger an event to a specific target.
 - `emit_filter` now filters based on [`EventTarget`](https://docs.rs/tauri/2.0.0/tauri/event/enum.EventTarget.html) instead of a window.
 - Renamed `listen_global` to `listen_any`. It now listens to all events regardless of their filters and targets.
+- JavaScript: `event.listen()` behaves similar to `listen_any`. It now listens to all events regardless of their filters and targets, unless a target is set in the `Options`.
+- JavaScript: `WebviewWindow.listen` etc. only listen to events emitted to the respective `EventTarget`.
