During the development of Linux v5.10 and its subsequent release, which soon had a corrective version, two things were being discussed, one clearer than the other. The first was whether it would be a Long Term Support version, and yes, it was; but the most serious debate was about how long it was going to be endured Linux 5.10LTS. I was surprised that they said that it would be endured less time than normal in this type of versions, but in the end it will not be like that.
At first it was said that it would be supported until the end of 2022, not as expected, but there are several teams and companies that have committed to help with its development and Linux 5.10 LTS will be supported and maintained until the end of 2026. The funny thing is that, before this last step, 5.10 was going to be supported for less time than 5.4 or even 4.19 and 4.14, kernels that will be supported until 2024. The main maintainer of the kernel, Greg Kroah-Hartman said that that time was going to be shortened due to lack of support, but that support has already arrived, so Linux 5.10 it will be endured the time we all expected.
Linux 5.10 LTS will be supported for the corresponding six years
The updated information already appears in the Linux kernel official website, where we see that the zero-point version arrived on December 13, 2020 and will reach the end of its life cycle (EOL) in December 2026. It is also mentioned that 5.4 will be maintained until December 2025, 4.19 until December 2024, 4.14 until January 2024, 4.9 until January 2023 and 4.4 until February 2022.
Linux 5.10 LTS came with news like updates to open source DRM, Fsync performance optimizations for Btrfs or F2FS enhancements including age threshold garbage collector, faster file decompression support, NVMe ZNS support, generic case folding.
