 Dependencies
-==========
+============
 
 - The dependencies required for :code:`i18n` are no longer part of the default package.
   If your application uses translation functionality, be sure to add an optional dependency:

+ChatMember tools
+================
+
+- Now :class:`aiogram.types.chat_member.ChatMember` no longer contains tools to resolve an object with the appropriate status.
+
+  .. code-block::
+
+    # Version 2.x
+    from aiogram.types import ChatMember
+
+    chat_member = ChatMember.resolve(**dict_data)
+
+  .. code-block::
+
+    # Version 3.x
+    from aiogram.utils.chat_member import ChatMemberAdapter
+
+    chat_member = ChatMemberAdapter.validate_python(dict_data)
+
+
+- Now :class:`aiogram.types.chat_member.ChatMember` and all its child classes no longer
+  contain methods for checking for membership in certain logical groups.
+  As a substitute, you can use pre-defined groups or create such groups yourself
+  and check their entry using the :func:`isinstance` function
+
+  .. code-block::
+
+    # Version 2.x
+
+    if chat_member.is_chat_admin():
+        print("ChatMember is chat admin")
+
+    if chat_member.is_chat_member():
+        print("ChatMember is in the chat")
+
+  .. code-block::
+
+    # Version 3.x
+
+    from aiogram.utils.chat_member import ADMINS, MEMBERS
+
+    if isinstance(chat_member, ADMINS):
+        print("ChatMember is chat admin")
+
+    if isinstance(chat_member, MEMBERS):
+        print("ChatMember is in the chat")
+
+  .. note::
+    You also can independently create group similar to ADMINS that fits the logic of your application.
+
+    E.g., you can create a PUNISHED group and include banned and restricted members there!
