The delay happened because Linus Torvalds had some Internet problems, and this made the Linux kernel 4.14 RC6 milestone a bit bigger than expected. This translates to the fact that it’s no longer clear if the next long-term supported kernel series will arrive on time, on November 5, 2017, or if it will get delayed with one week. The sixth Release Candidate of the upcoming Linux 4.14 LTS kernel brings updated drivers, in particular for GPU, USB, networking, media, and input, some selftest updates, various improvements to supported architectures and filesystems, as well as documentation and updates and a few core kernel and key handling changes.
