I notice 3.9 is still listed as supported at https://kafka.apache.org/community/downloads/ Do we have any thoughts on whether there will be a 3.9.3? From: Matthias J. Sax < mjsax@apache.org > Date: Tuesday, 25 November 2025 at 11:28 To: users@kafka.apache.org < users@kafka.apache.org > Subject: Re: Trying to gauge the eol for Kafka 3.9.1. Please help. Cf https://cwiki.apache.org/confluence/display/KAFKA/Time+Based+Release+Plan#TimeBasedReleasePlan-WhatIsOurEOLPolicy ? In general, we maintain 3 versions, so with AK 4.2 release, 3.9.x would actually hit EOL. Given that 4.0 is a major change with ZK removal in favor of KRaft, it will most likely be maintained a little longer though. We are currently discussing a 3.9.2 bug-fix release. But it will depend on overall community demand, if their will be a 3.9.3 bug-fix release or not. In general, I would not expect 3.9.x to be maintained too much longer, and migrating off ZK, and to upgrade to 4.x is h...

Hi all, Just wondering how to interpret KIP-1101 release notes please. The summary says it's part of 4.1.0: https://kafka.apache.org/blog/2025/09/04/apache-kafka-4.1.0-release-announcement/ But the release notes don't mention it: https://archive.apache.org/dist/kafka/4.1.0/RELEASE_NOTES.html Ah, searching for the title I find this: [KAFKA-17747< https://issues.apache.org/jira/browse/KAFKA-17747 >] - Trigger rebalance on rack topology changes So it's changed number maybe? Also wonder if any performance benchmarking results are available please?

If you look at the dependancies for 4.0.2 and 4.1.2 you can see that Jetty 12.0.25 is present there. https://github.com/apache/kafka/blob/4.0.2/gradle/dependencies.gradle https://github.com/apache/kafka/blob/4.1.2/gradle/dependencies.gradle Kind regards, JIm > On 20 Mar 2026, at 05:21, Ashish Verma V < ashish.v.verma@ericsson.com > wrote: > > Hi Jim, > > Any update on this query. > > Thanks > Ashish Verma > From: Apoorva Maheshwari < apoorva.maheshwari@ericsson.com > > Sent: 16 March 2026 08:39 > To: Jim Halfpenny <jim.halfpenny@stackable.tech> > Cc: users@kafka.apache.org ; Steven Schlansker < stevenschlansker@gmail.com >; users-subscribe@kafka.apache.org ; Abhishek Kant Rattan < abhishek.kant.rattan@ericsson.com >; Sahil Sharma D < sahil.d.sharma@ericsson.com >; Ashish Verma V < ashish.v.verma@ericsson.com > > Subject: RE: Version info that supports Jetty v12.0.25 > ...
