+
+The Apache Flink Community is pleased to announce the third bug fix release of
the Flink 1.19 series.
+
+This release includes 14 bug fixes, vulnerability fixes, and minor
improvements for Flink 1.19.
+Below you will find a list of all bugfixes and improvements (excluding
improvements to the build infrastructure and build stability). For a complete
list of all changes see:
+[JIRA](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315522&version=12355441).
+
+We highly recommend all users upgrade to Flink 1.19.3 or higher.
+
+<div class="alert alert-warning" role="alert">
+<b>Note:</b> This release contains an improvement regarding how the Adaptive
Scheduler works by default on Kubernetes deployments.
+
+Beforehand, in case of a downscaling, the Adaptive Scheduler was not striving
to minimize the active TaskManager number, and free up resources even if it
would have been possible.
+This logic is now changed and by default the Adaptive Scheduler will try to
maximize TaskManager utilization during a downscale event to be able to
minimize the necessary TaskManager number.
+
+Although this behavioral change pushes the boundaries of a patch release, the
community agreed that the applied default is expected in the vast majority of
use-cases.
+To keep the previous strategy, make sure you set the
`jobmanager.adaptive-scheduler.prefer-minimal-taskmanagers` configuration
option to `false`.
+For more details, please see <a
href='https://issues.apache.org/jira/browse/FLINK-33977'>FLINK-33977</a>.
