IDBVersionChangeRequest

Warning: The latest specification does not include this interface anymore as the IDBDatabase.setVersion() method has been removed. See the compatibility table for version details.
The new way to do it is to use the IDBOpenDBRequest interface which has now the onblocked handler and the newly needed onupgradeneeded one.

The IDBVersionChangeRequest interface the IndexedDB API represents a request to change the version of a database. It is used only by the setVersion() method of IDBDatabase.

Methods
