`persist_scrollback` is gone, and with it the switch, its three translations and the branches that read it. Keeping a capped tail of each pane's output is now what the daemon does, not something it can be asked to do. This reverses the call made when the feature landed. The argument for off-by-default was that the ring holds whatever the pane printed — echoed tokens, `env` output, an agent's transcript — and that writing that down should be the user's decision to make. What the argument missed is when the decision gets made: the moment anyone learns they wanted this is the moment a daemon has already died, and by then the setting could only be turned on for next time. A feature whose entire purpose is to survive an event nobody schedules cannot be opt-in. The cost is real and does not go away: pane output now lives at `<config>/scrollback/*.bin` on every machine, 0600 on unix and behind the config directory's ACL on Windows, capped at 256 KiB per pane and dropped as soon as no window can still ask for it. Old configs naming the key still parse — nothing in `Config` refuses unknown fields — so the key simply stops meaning anything.
tty7
A terminal workbench: persistent sessions, remote work, agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
Why
- Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
- Editor-grade input — suggestions, completion, highlighting, history search
- Remote development — files, repos, panes, and git data stay on the remote machine
- Native SSH — profiles, SFTP, port forwarding, and jump hosts
- Agent-aware — Claude Code, Codex & co.: status, notifications, git context
- CLI + Skills — agents create panes, run commands, and inspect output
