A new OpenBSD release means a ton of new features, and OpenBSD 7.4 is no different. It adds a VirtIO GPU driver, built-in leak detection for malloc, support for AMD processor microcode updates, and a whole lot more. If you want the really detailed list of changes, hop on over to the changelog, and OpenBSD users will already know how to update.
Cool! The only OS where I look forward to upgrades, the OpenBSD crew keep it simple.
Done, easy.
