+Subject: [PATCH] Add PlayerConnectionCloseEvent
+
+This event is invoked when a player has disconnected. It is guaranteed that,
+if the server is in online-mode, that the provided uuid and username have been
+validated.
+
+The event is invoked for players who have not yet logged into the world, whereas
+PlayerQuitEvent is only invoked on players who have logged into the world.
+
+The event is invoked for players who have already logged into the world,
+although whether or not the player exists in the world at the time of
+firing is undefined. (That is, whether the plugin can retrieve a Player object
+using the event parameters is undefined). However, it is guaranteed that this
+event is invoked AFTER PlayerQuitEvent, if the player has already logged into
+the world.
+
+This event is guaranteed to never fire unless AsyncPlayerPreLoginEvent has
+been called beforehand, and this event may not be called in parallel with
+AsyncPlayerPreLoginEvent for the same connection.
+
+Cancelling the AsyncPlayerPreLoginEvent guarantees the corresponding
+PlayerConnectionCloseEvent is never called.
+
+The event may be invoked asynchronously or synchronously. As it stands,
+it is never invoked asynchronously. However, plugins should check
+Event#isAsynchronous to be future-proof.
+
+On purpose, the deprecated PlayerPreLoginEvent event is left out of the
+API spec for this event. Plugins should not be using that event, and
+how PlayerPreLoginEvent interacts with PlayerConnectionCloseEvent
+is undefined.
