+Auto-registering
+****************
+
+We've changed the method of automatically registering commands to API to reduce the request amount
+and prevent rate limit. So, `auto_register` and `auto_delete` parameter is now removed. Please change your SlashContext
+params like this.
+
+Before:
+
+.. code-block:: python
+
+    slash = SlashContext(..., auto_register=True, auto_delete=True)
+
+After:
+
+.. code-block:: python
+
+    slash = SlashContext(..., sync_commands=True)

 It got deleted, so please remove all of it if you used it.

+Also, we've added `connector` parameter, which is for helping passing options as kwargs
+if your command option is other that english.
