Submission + - Ubuntu 23.10 is a Minotaur that moves faster and takes up less space (arstechnica.com)
Two of the biggest changes in Ubuntu 23.10 are in the installer. Ubuntu now defaults to a "Default installation," which is quite different from what the "default" was even just one release prior. "Default" is described as "Just the essentials, web browser, and basic utilities," while "Full" is "An offline-friendly selection of office tools, utilities, web browser, and games." "Default" is somewhat similar to what "Minimal" used to be in prior versions, while "Full" is intended for those who are offline or have slow connections or just want as many options as possible right away.
Elsewhere in the installer, you can now choose ZFS as your primary file system. There's also an experimental option to set up Trusted Platform Module (TPM) full-disk encryption rather than rely entirely on passphrases to encrypt your disk. This brings Ubuntu up to speed with Windows in offering a way to both secure your system and find out the hard way that you lack a backup key to get in after messing with your boot options. (Kidding! Somewhat.)
