Unclear It is not shown which terminal feature this check is for.
What
Claude Code checks the terminal it runs in to see whether a feature is likely to work. tmux and screen are programs that run several terminal sessions inside one window.
tmux: the check now reports the feature as not likely to work.
screen: the check still says it is not supported, now with the message env: inside screen, not supported instead of one naming both programs and ending in "not supported yet".
Why
tmux is now handled on its own instead of being grouped with screen.
