Hi, All. As planned, the branch-4.1 has been successfully created for Spark 4.1, and the master branch has been updated to target Spark 4.2.
Please track all Spark 4.1 and 4.2 activities through the following umbrella JIRA issues: - SPARK-51166: Prepare Apache Spark 4.1.0 - SPARK-54137: Prepare Apache Spark 4.2.0 Note that our goal is to deliver Apache Spark 4.1.0 without blocking your contributions. Contributions to Apache Spark 4.2.0 are always welcome, and the master branch remains open for everyone. Depending on your current development progress, you can choose which version to focus on. We highly recommend planning the delivery of your work items and refining completed ones ASAP. For example: - SPARK-54174 (Remove override of deprecated method SparkThrowable#getErrorClass) has been added to 4.2.0 as a normal improvement. - SPARK-51169 (Add Python 3.14 support in Spark Classic) remains under 4.1.0, with a few pending tasks such as SPARK-54046 (Upgrade PyArrow to 22.0.0). If these pending issues are not resolved by mid-November, we will need to move this work from 4.1 to 4.2. - SPARK-51167 (Build and Run Spark on Java 25) has already been moved from 4.1 to 4.2 due to blocking issues. Best regards, Dongjoon Hyun.
