So there you have it, Canonical kept on its promise to rebase the Ubuntu 17.10 release on the Linux 4.13 kernel series, and with today’s repo sync, the previous Linux 4.12 kernel, which is now EOL (End-of-Life) upstream, were replaced by a 4.13.0-11 kernel that’s apparently based on Linux kernel 4.13.1. Ubuntu 17.10 is also using the latest GCC 7.2 compiler and Mesa 17.2.1 graphics stack by default. Linux kernel 4.13 launched earlier this month and comes with numerous new features and improvements, among which we can mention support for Intel’s Cannon Lake and Coffee Lake CPUs, support for “lifetime hints” in the block layers and the virtual filesystem, AppArmor enhancements, and better power management.
