The 4.3 branch of the Linux kernel is a really popular one and it’s been adopted by many distros. From the looks of it, the maintainers will continue to provide support for it, but it’s not clear for how long. There is already a 4.1.15 version that has been declared long-term, so it’s difficult to say if another branch will be tagged LTS as well, after such a short time.
As you would expect, Linux kernel 4.3.3 is not a huge update, but it comes with its fair share of driver updates and file system changes. Users are advised to upgrade to the new version, but most likely they will just have to wait until this version makes it into the repositories.
