I have Ubuntu 16.04.4 LTS and the Linux kernel version is 4.13.0-39. But in The Linux Kernel Archives I can't find version 4.13.
Edit 1: How do they choose what Linux kernel version to put in the next point release of LTS version with LTS Enablement Stack?
Edit 2: What are the criterias to pick a Linux kernel version and put in a Ubuntu version?
LTS enablement stack bring new Linux kernel version along with a point release, but wouldn't that bring the "bugs" from the recently released version?
