+
+Stateful Functions is a cross-platform stack for building Stateful Serverless
applications, making it radically simpler to develop scalable, consistent, and
elastic distributed applications.
+This new release brings various improvements to the StateFun runtime, a leaner
way to specify StateFun module components, and a brand new JavaScript SDK!
+
+The binary distribution and source artifacts are now available on the updated
[Downloads](https://flink.apache.org/downloads.html)
+page of the Flink website, and the most recent Java SDK, Python SDK,, GoLang
SDK and JavaScript SDK distributions are available on
[Maven](https://search.maven.org/artifact/org.apache.flink/statefun-sdk-java/3.2.0/jar),
[PyPI](https://pypi.org/project/apache-flink-statefun/),
[Github](https://github.com/apache/flink-statefun/tree/statefun-sdk-go/v3.2.0),
and [npm](https://www.npmjs.com/package/apache-flink-statefun) respectively.
+You can also find official StateFun Docker images of the new version on
[Dockerhub](https://hub.docker.com/r/apache/flink-statefun).
+
+For more details, check the complete [release
changelog](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315522&version=12350540)
+and the [updated
documentation]({{site.DOCS_BASE_URL}}flink-statefun-docs-release-3.2/).
+We encourage you to download the release and share your feedback with the
community through the [Flink mailing
lists](https://flink.apache.org/community.html#mailing-lists)
+or [JIRA](https://issues.apache.org/jira/browse/)!

+## New Features
+
+### A brand new JavaScript SDK for NodeJS
+
+Stateful Functions provides a unified model for building stateful applications
across various programming languages and deployment environments.
+The community is thrilled to release an official JavaScript SDK as part of the
3.2.0 release.
+
+```js
+const http = require("http");
+const {messageBuilder, StateFun, Context} = require("apache-flink-statefun");
+
+let statefun = new StateFun();
+statefun.bind({
+ typename: "com.example.fns/greeter",
+ fn(context, message) {
+ const name = message.asString();
+ let seen = context.storage.seen || 0;
+ seen = seen + 1;
+ context.storage.seen = seen;
+
+ context.send(
+ messageBuilder({typename: 'com.example.fns/inbox',
+ id: name,
+ value: `"Hello ${name} for the ${seen}th time!"`})
+ );
+ },
+ specs: [{
+ name: "seen",
+ type: StateFun.intType(),
+ }]
+});
+
+http.createServer(statefun.handler()).listen(8000);
+```
+
+As with the Python, Java and Go SDKs, the JavaScript SDK includes:
+
+ - An address scoped storage acting as a key-value store for a particular
address.
+ - A unified cross-language way to send, receive and store values across
languages.
+ - Dynamic `ValueSpec` to describe the state name, type, and possibly
expiration configuration at runtime.
+
+You can get started by adding the SDK to your project.
+
+`npm install apache-flink-statefun@3.2.0`
+
+For a detailed SDK tutorial, we would like to encourage you to visit:
+
+ - [JavaScript SDK
Documentation]({{site.DOCS_BASE_URL}}flink-statefun-docs-release-3.2/docs/sdk/js/)
+
+### Support different remote functions module names
+
+With the newly introduced configuration option `statefun.remote.module-name`,
it is possible to override the default remote module file name (`module.yaml`).
+
+To provide a different name, for example `prod.yaml` that is located at
`/flink/usrlib/prod.yaml`, one can add the following to ones `flink-conf.yaml`:
+
+```bash
+statefun.remote.module-name: /flink/usrlib/prod.yaml
+```
+
+For more information see
[FLINK-25308](https://issues.apache.org/jira/browse/FLINK-25308).
+
+### Allow creating custom metrics
+
+The embedded SDK now supports registering custom counters.
+For more information see
[FLINK-22533](https://issues.apache.org/jira/browse/FLINK-22533).
+
+### Upgraded Flink dependency to 1.14.3
+
+Stateful Functions 3.2.0 runtime uses Flink 1.14.3 underneath.
+This means that Stateful Functions benefits from the latest improvements and
stabilisations that went into Flink.
+For more information see [Flink's release
announcement](https://flink.apache.org/news/2022/01/17/release-1.14.3.html).
