At the 2020 Open Source Summit Europe, Greg Kroah-Hartman announced the upcoming 5.10 kernel release will be the latest Long Term Support (LTS) kernel. The current LTS kernel was 5.4, released in 2019, and will receive updates until 2025. This means the 5.10 kernel should receive updates all the way into 2026.

The first RC (Release Candidate) for the 5.10 kernel was released in October, 2020, which will be followed by numerous other release candidates. The stable version of the 5.10 kernel should be officially available in December, 2020. 

Some of the more important features to be found in the 5.10 kernel include AMD Zen 3 CPU support, support for the new Ryzen 5000 line of CPUs, Intel Rocket Lake support, an open source driver for Radeon RX 6000 GPUs, and numerous file system and storage optimizations. An old memory feature that dated back to 286 processes has finally been removed as well. 

Other than 5.10 being an LTS release, this kernel won't be considered anything remarkably special. However, it is important to note that LTS kernels include back-ported bug fixes for older kernel trees. So when an LTS kernel is released, chances are very good your distribution of choice will be using it for some time.
