/>
+   Applications that are using the Pulsar v1 API, deprecated since 2.0 release, need to update
the
+   Maven dependency to use the `pulsar-client-1x` artifact instead of `pulsar-client`. Eg.
+   ```xml
+   <dependency>
+       <groupId>org.apache.pulsar</groupId>

+   ([Javadoc](https://pulsar.apache.org/api/client/org/apache/pulsar/client/api/PulsarClient.html#getPartitionsForTopic-java.lang.String-))
+ * Added `Consumer.pauseMessageListener()` and `Consumer.resumeMessageListener()` [#2961](https://github.com/apache/pulsar/pull/2961)
+ * Removed shading relocations for Circe-checksum and lz4 libraries, to ensure native libraries
+   are correctly loaded when using shaded client lib. [#2191](https://github.com/apache/pulsar/pull/2191)
+
+#### Python client
+ * Fixed `Message.properties()` [#3595](https://github.com/apache/pulsar/pull/3595)
+
+#### Go client
+ * Added `Producer.flush()` to flush all outstanding messages [#3469](https://github.com/apache/pulsar/pull/3469)
+ * Support `Consumer.Seek()` [#3478](https://github.com/apache/pulsar/pull/3478)

 Review comment:
   @merlimat Can we add the following: in terms of package management, replace the `dep` with
`go mod`. After that, we may need to update the installation and deployment documentation
for pulsar-client-go, because this is quite different from the package management method that
used `dep` before.
