+
+The Apache Flink community released the first bugfix version of the Apache Flink 1.12 series.
+
+This release includes 79 fixes and minor improvements for Flink 1.12.0. The list below includes a detailed list of all fixes and improvements.
+
+We highly recommend all users to upgrade to Flink 1.12.1.
+
+<div class="alert alert-danger small" markdown="1">
+<b>Attention:</b>
+Using UnalignedCheckpoints in Flink 1.12.0 combined with two/multiple inputs tasks or with union inputs for single input tasks can result in corrupted state.
+
+This can happen if a new checkpoint is triggered before recovery is fully completed. For state to be corrupted a task with two or more input gates must receive a checkpoint barrier exactly at the same time this tasks finishes recovering spilled in-flight data. In such case this new checkpoint can succeed, with corrupted/missing in-flight data, which will result in various deserialisation/corrupted data stream errors when someone attempts to recover from such corrupted checkpoint.

+
+Updated Maven dependencies:
+
+```xml

+
+Notice:
+<ul>
+<li>The DockerHub <a href='https://hub.docker.com/_/flink'>official images</a> for Apache Flink 1.12.1 are temporary missing. As an alternative, the images are currently available on the Flink PMC managed <a href='https://hub.docker.com/r/apache/flink'>registry</a>. This is now also the default for the Native Kubernetes deployments. The Flink PMC will keep working with the DockerHub team to deliver the official images.</li>

Review comment:
       nit: https://hub.docker.com/r/apache/flink is not a separate registry. Actually, it has the same registry with official image, which is docker hub. Instead, it is a dedicated repository managed by Flink PMC member. 
   
   So I suggest to rename the registry to repository here.
