Hi, All. Since the Apache Spark 4.0.0 tag was created in May, more than three months have passed.
https://github.com/apache/spark/releases/tag/v4.0.0 (2025-05-19) So far, 124 commits (mostly bug fixes) have been merged into the branch-4.0 branch. $ git log --oneline v4.0.0...HEAD | wc -l 124 I think it's time to release v4.0.1 to deliver these bug fixes to Apache Spark 4 users. What do you think? I'm also volunteering to serve as the release manager for Apache Spark 4.0.1. Let me know if you need any additional backport patches. I plan to start the RC vote on 2025-09-02. Best regards, Dongjoon Hyun. PS. I don't think any PyPi issues need to block the ASF release processes. So, the official ASF distribution channels and Maven Central are the main target for this release.
