Linus Torvalds, the principal developer of the mainline Linux branch, released version 5.15 of the open source kernel over the Halloween weekend, and it has just been tagged as the next Long Term Support (LTS) release.
The kernel designates one release every year as an LTS release, which the developers and the community commit to maintain for at least two years.
By this logic, Linux 5.15 will not reach end-of-life before October 2023. However, of late, the kernel has adopted a policy of supporting LTS releases for as long as its commercial users are willing to put up the required resources to maintain it.
