SparkyLinux 4.6 entered development only two months ago, in early March, and it relies on the packages from the Debian Testing repositories, which will soon become Debian GNU/Linux 9 “Stretch.” How soon? We don’t know yet because the Debian Project didn’t announce a release date for the Stretch stable series. However, it should launch something this month, and so will SparkyLinux 4.6, which today received a Release Candidate (RC) build that it’s, of course, based on the software repositories of the upcoming Debian GNU/Linux 9 “Stretch” operating system, running the latest kernel from the Linux 4.10 branch.
