Hey Ashwin, Thanks for your question!
I believe we have only removed support for two Java versions: 7: https://cwiki.apache.org/confluence/display/KAFKA/KIP-118%3A+Drop+Support+for+Java+7 in 2.0 8: https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=181308223 in 4.0 In both cases, we changed the gradle sourceCompatibility and targetCompatibility at the same time, which I believe changes the "-target" option in javac. We have no plans currently for dropping support for 11 or 17, but I presume they would work in much the same way. Hope this helps!
