Today we are releasing version 6.2 of Raspberry Pi OS, the second update to the 'Trixie' version we released last year. This update is mostly a round-up of all the small changes and bug fixes we have made over the past few months, but there is one significant change that we’d like to flag up - passwordless sudo is now disabled by default. Given the ever-increasing threat of cybercrime, we continually review the security of Raspberry Pi OS to ensure it is sufficiently robust to withstand potential attacks. This is always a tricky balance, as anything that makes the operating system more secure will invariably inconvenience legitimate users to some extent, so we try to keep such changes to a minimum. This particular security update is one that many users may not even notice, but it will affect some.
