Greg Kroah-Hartman, responsible for maintaining the stable branch of the Linux kernel, announced the release of the final version of Linux kernel 4.14.336, which will be the last in this series. The 4.14 branch was released in November 2017 and has been supported for 6 years. It is recommended to transition products running on kernel 4.14 to more current LTS releases.
Kernel developers continue to maintain the following long-term branches:
- 6.6 — until December 2026 (used in Ubuntu 24.04).
- 6.1 — until December 2026 + support under SLTS (used in Debian 12 and the main branch of OpenWRT).
- 5.15 — until October 2026 (used in Ubuntu 22.04, Oracle Unbreakable Enterprise Kernel 7 and OpenWRT 23.05).
- 5.10 — until December 2026 + support within SLTS (used in Debian 11, Android 12 and OpenWRT 22).
- 5.4 — until December 2025 (used in Ubuntu 20.04 LTS and in Oracle Unbreakable Enterprise Kernel 6)
- 4.19 — until December 2024 + support under SLTS (used in Debian 10 and in Android 10).
Separately based on kernels 4.4, 4.19, 5.10, and 6.1, the Linux Foundation provides SLTS (Super Long Term Support) branches, which are supported separately and maintained for 10-20 years. SLTS branches are supported within the Civil Infrastructure Platform (CIP) project, which includes companies such as Toshiba, Siemens, Renesas, Bosch, Hitachi, and MOXA, as well as LTS branch maintainers, Debian developers, and creators of the KernelCI project. SLTS kernels are aimed at applications in civil infrastructure technical systems and in critical industrial systems.
