+Extension Migration Configuration
+----------------------------------
+
+Extension migrations now receive automatic version prefixes and configuration has been simplified:
+
+1. **Version Prefixing** (Automatic)
+
+   Extension migrations are automatically prefixed to prevent version collisions:
+
+   .. code-block:: text
+
+      # User migrations
+      0001_initial.py       → version: 0001
+
+      # Extension migrations (automatic prefix)
+      0001_create_tables.py → version: ext_adk_0001
+      0001_create_session.py → version: ext_litestar_0001
+
+2. **Configuration Format** (Important)
+
+   Extension settings must be in ``extension_config`` only:
+
+   .. code-block:: python
+
+      # Incorrect format
+      migration_config={
+          "include_extensions": [
+              {"name": "adk", "session_table": "custom"}
+          ]
+      }
+
+      # Correct format
+      extension_config={
+          "adk": {"session_table": "custom"}
+      },
+      migration_config={
+          "include_extensions": ["adk"]  # Simple string list
+      }
+
+**Configuration Guide**: See :doc:`/migration_guides/extension_config`
+
+Features
+--------
+
+- Extension migrations now automatically prefixed (``ext_adk_0001``, ``ext_litestar_0001``)
+- Eliminated version collision between extension and user migrations
+- Simplified extension configuration API
+- Single source of truth for extension settings (``extension_config``)
+
+Bug Fixes
+---------
+
+- Fixed version collision when extension and user migrations had the same version number
+- Fixed duplicate key violation in ``ddl_migrations`` table when using extensions
+- Improved migration tracking with clear extension identification
+
+Technical Changes
+-----------------
+
+- ``_load_migration_metadata()`` now accepts optional ``version`` parameter
+- ``_parse_extension_configs()`` rewritten to read from ``extension_config`` only
+- Extension migration version prefixing handled in ``_get_migration_files_sync()``
+- Removed dict format support from ``include_extensions``
+
+**Previous Versions**
