Whether you don’t have Bullseye yet or want to try the beta version, you are in the right place. The latest Raspberry Pi OS version available for download is currently “Bullseye”, based on Debian 11, but it’s already possible to try the one based on Debian 12 (aka “Bookworm”). Raspberry Pi OS is based on Debian and follows its versions, usually with some time lag between the two.
