Linux Kernel 4.13 was released earlier this month and includes a number of new features and enhancements that support Intel's Cannon Lake and Coffee Lake processors, support for virtual file systems, enhanced AppArmor, and better power management.
Also worth noting is that since Picuntu 17.10 (Artful Aardvark), Canonical will no longerserverAnd the desktop platform provide i386 architecture ISO system image, but still support the Ubuntu version, as well as Ubuntu Core, Cloud, Container, NetInst and Server (subiquity) to provide security updates.
According to Ubuntu 17.10 release roadmap, will be October 5, 2017 into the kernel freeze phase, which means that before the official release on October 19 will not do too much adjustment to the kernel part. It is regrettable that the 4.13 branch is not a long-term version, but Ubuntu 17.10 is also not the LTS version, the support period of 9 months, until 2018 in July.
