The Apache Flink Community is pleased to announce the first bug fix release of the Flink 1.18 series.

This release includes 47 bug fixes, vulnerability fixes, and minor improvements for Flink 1.18. 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 1.18.1.

Note: Users that have state compression should not migrate to 1.18.1 (nor 1.18.0) due to a critical bug that could lead to data loss. Please refer to FLINK-34063 for more information.
