Coming four months after the last Alpha milestone, the Release Candidate (RC) of the Debian Bullseye Installer is here to bump kernel support from Linux 5.9 to the long-term supported Linux 5.10 LTS kernel series, which I think it will be the final kernel that Debian GNU/Linux 11 “Bullseye” will ship with.
Of course, this change alone brings better hardware support, but the Debian Installer Bullseye Release Candidate also adds support for several single-board computers, such as the Banana Pi BPI-M2-Ultra, Banana Pi BPI-M3, Orange Pi One Plus, ROCK Pi 4a, ROCK Pi 4b, and ROCK Pi 4c, as well as support for the Rockchip RK3399 processor found in numerous devices.
