This extend LTS only applies to the primary Apache Spark project/repo and does not apply to sub projects with separate repos/releases (namely: Spark Connect for Swift/Rust/Go and Spark Kubernetes operator). Additionally, as Java 8 support may be removed from other projects (including Hadoop), should a dependency have a security fix that is not backported to a Java 8 compatible version we may decide to mark that vulnerability as a won&#8217;t fix or release the new version without Java 8 support.</p>
