archlinux/archinstall 4.0

4.0 - Textual UI

on GitHub

Personal note: I (@Torxed) usually spend a bit of time curating these release notes.. However, I won't have time to clean up the "what's changed" this time, so it will be auto generated this release.. not that anyone probably cares but thought I should apologize anyway

New TUI

We (thanks to major work by @svartkanin) have swapped from curses to textual. This enables us to (hopefully) meet modern expectations in the terminal and look better in the process, as well as make it easier to maintain a lot of the menu stuff. Please be patient as we're transitioning to this new look and feel, as always with change — feedback is welcome, especially related to accessibility features.
