+API stability and deprecation policy
+------------------------------------
+
+aiohttp tries to not break existing users code.
+
+Obsolete attributes and methods are marked as *deprecated* in
+documentation and raises :class:`DeprecationWarning` on usage.
+
+Deprecation period is usually a year and half.
+
+After the period is passed out deprecated code is be removed.
+
+Unfortunately we should break own rules if new functionality or bug
+fixing forces us to do it (for example proper cookies support on
+client side forced us to break backward compatibility twice).
+
+All *backward incompatible* changes are explicitly marked in
+:ref:`CHANGES <aiohttp_changes>` chapter.
