+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This library version introduces the following breaking changes:
+
+- The following methods return ``void`` instead of the raw command
+  response:
+
+  - ``MongoDB\\Client``: ``dropDatabase()``
+  - ``MongoDB\\Collection``: ``drop()``, ``dropIndex()``,
+    ``dropIndexes()``, ``dropSearchIndex()``, ``rename()``
+  - ``MongoDB\\Database``: ``createCollection()``, ``drop()``,
+    ``dropCollection()``, ``renameCollection()``
+
+  The ``MongoDB\\Database::createEncryptedCollection()`` method returns
+  the list of encrypted fields instead of the raw command response.
+
+  If there is an error, the methods throw an exception.
+
+  If you must access the raw command response from the preceding
+  methods, you can register a :php:`CommandSubscriber
+  <mongodb-driver-monitoring-commandsubscriber>` in your application.
