+# 0.5.5
+
+*  Fix for alembic autogenaration of migration `UUID` columns. It should just produce sqlalchemy `CHAR(32)` or `CHAR(36)`
+*  In order for this to work you have to set user_module_prefix='sa.' (must be equal to sqlalchemy_module_prefix option (default 'sa.'))
+
 # 0.5.4
 
 *  Allow to pass `uuid_format` (allowed 'hex'(default) or 'string') to `UUID` field to change the format in which it's saved.
