After seven weeks of development, Linux 5.10 is finally here as the latest and greatest kernel series for GNU/Linux distributions wanting top-notch hardware support. Not only that, but it’s a long-term supported (LTS) branch, which means that it will probably receive support for the next 5 years. Highlights of Linux kernel 5.10 LTS include support for the ARMv8.5 memory tagging extension, support for the SM2 digital-signature algorithm, support for the ISO 15765-2:2016 CAN transport protocol, support for the IGMPv3/MLDv2 multicast protocol, and support for Amazon Nitro enclaves.
