+Intents Are Now Required
+--------------------------
+
+In earlier versions, the ``intents`` keyword argument was optional and defaulted to :meth:`Intents.default`. In order to better educate users on their intents and to also make it more explicit, this parameter is now required to pass in.
+
+For example:
+
+.. code-block:: python3
+
+    # before
+    client = discord.Client()
+
+    # after
+    intents = discord.Intents.default()
+    client = discord.Client(intents=intents)
+
+This change applies to **all** subclasses of :class:`Client`.
