         For users who have customized window store implementations on the above interface, they'd need to update their code to implement the newly added method as well.
         For more details, see <a href="https://cwiki.apache.org/confluence/display/KAFKA/KIP-261%3A+Add+Single+Value+Fetch+in+Window+Stores">KIP-261</a>.

+        We have added public <code>WindowedSerdes</code> to allow users to read from / write to a topic storing windowed table changelogs directly.
+        In addition, in <code>StreamsConfig</code> we have also added <code>default.windowed.key.serde.inner</code> and <code>default.windowed.value.serde.inner</code>
+        to let users specify inner serdes if the default serde classes are windowed serdes.
+        For more details, see <a href="https://cwiki.apache.org/confluence/display/KAFKA/KIP-265%3A+Make+Windowed+Serde+to+public+APIs">KIP-265</a>.

     <p>
         We have added support for methods in <code>ReadOnlyWindowStore</code> which allows for querying <code>WindowStore</code>s without the necessity of providing keys.
