+<title>Stateful Functions 2.2.1 Release Announcement</title>
+<description><p>The Apache Flink community released the first bugfix
release of the Stateful Functions (StateFun) 2.2 series, version
2.2.1.</p>
+
+<p>This release fixes a critical bug that causes restoring the Stateful
Functions cluster from snapshots (checkpoints or
+savepoints) to fail under certain conditions. Starting from this release,
StateFun now creates snapshots with a more
+robust format that allows it to be restored safely going forward.</p>
+
+<p><b><i>We strongly recommend all users to upgrade to
2.2.1</i></b>. Please see the following sections on instructions
and things to
+keep in mind for this upgrade.</p>
+
+<h2
id="for-new-users-just-starting-out-with-stateful-functions">For
new users just starting out with Stateful Functions</h2>
+
+<p>We strongly recommend to skip all previous versions and start using
StateFun from version 2.2.1.
+This guarantees that failure recovery from checkpoints, or application
upgrades using savepoints will work as expected for you.</p>
+
+<h2 id="for-existing-users-on-versions--220">For existing
users on versions &lt;= 2.2.0</h2>
+
+<p>Users that are currently using older versions of StateFun may or may
not be able to directly upgrade to 2.2.1 using
+savepoints taken with the older versions. <b>The Flink community is
working hard on a follow-up hotfix release, 2.2.2,
+that would guarantee that you can perform the upgrade smoothly</b>. For
the meantime, you may still try to upgrade to 2.2.1
+first, but may encounter <a
href="https://issues.apache.org/jira/browse/FLINK-19741">FLINK-19741</a>
or
+<a
href="https://issues.apache.org/jira/browse/FLINK-19748">FLINK-19748</a>.
If you do encounter this, do not worry about data
+loss; this simply means that the restore failed, and you’d have to wait until
2.2.2 is out in order to upgrade.</p>
+
+<p>The follow-up hotfix release 2.2.2 is expected to be ready within
another 2~3 weeks, as it <a
href="http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/DISCUSS-Releasing-Apache-Flink-1-11-3-td45989.html">requires
a new hotfix release
+from Flink core</a>,
+and ultimately an upgrade of the Flink dependency in StateFun. We’ll update
the community via the Flink
+mailing lists as soon as this is ready, so please subscribe to the mailing
lists for important updates for this!</p>
+
+<hr />
+
+<p>You can find the binaries on the updated <a
href="/downloads.html">Downloads page</a>.</p>
+
+<p>This release includes 6 fixes and minor improvements since StateFun
2.2.0. Below is a detailed list of all fixes and improvements:</p>

-<title>Flink 1.1.1 Released</title>
-<description><p>Today, the Flink community released Flink version
1.1.1.</p>
-
-<p>The Maven artifacts published on Maven central for 1.1.0 had a Hadoop
dependency issue: No Hadoop 1 specific version (with version 1.1.0-hadoop1) was
deployed and 1.1.0 artifacts have a dependency on Hadoop 1 instead of Hadoop
2.</p>
-
-<p>This was fixed with this release and we <strong>highly
recommend</strong> all users to use this version of Flink by bumping your
Flink dependencies to version 1.1.1:</p>
