The first point release in the Alpine Linux 3.3 series updates many of the distribution’s core components. For example, the OS is now based on the Linux kernel 4.1.15 LTS packages, for which the devs rebuilt many tools, including open-vm-tools-grsec, ipfw-grsec, xtables-addons-grsec, dahdi-linux-grsec, and devicemaster-linux-grsec.
