title: “Apache Flink 1.19.2 Release Announcement” date: “2025-02-12T00:00:00.000Z” aliases:
The Apache Flink Community is pleased to announce the second bug fix release of the Flink 1.19 series.
This release includes 73 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.
We highly recommend all users upgrade to Flink 1.19.2.
The Flink community agreed to include this update in a patch release, despite minor differences in default memory allocation between Netty 3 and Netty 4. By default, Netty 4 allocates slightly more memory to improve performance. However, we believe this will have no impact on the vast majority of use cases.
For a detailed overview of these differences and available configuration options, please refer to the relevant section of the [Flink documentation]({{< param DocsBaseUrl >}}flink-docs-release-1.19/docs/deployment/memory/mem_tuning/#configure-memory-for-netty4).
