Unreleased

0.10.0 - 2026-07-11

Added

• Tab completion now executes the completion specs' dynamic generators: positions whose candidates come from the live system get real values — git branches on git checkout <Tab>, container names for docker/podman, package.json scripts for npm/pnpm/bun/yarn, cargo/rustup/tmux/brew/apt/pip listings, and more. Scripts run off the main thread in the session's cwd (800 ms timeout, output capped, short-lived cache) and their results merge into the already-open menu as they arrive; a slow or failing generator just contributes nothing. (#52)
• When shell integration never engages in a pane, pressing Ctrl+R now explains why the history menu can't appear (once per pane, dismissed by the next keystroke) instead of failing silently — naming the wrapper when a figterm-style PTY shim (kiro-cli-term, figterm, qterm) is intercepting the shell's OSC 133 reports. The chord still reaches the shell, so its own reverse-i-search keeps working. (#46)

Fixed

• ssh <Tab> (and scp/sftp/rsync) now completes host aliases from ~/.ssh/config — Include files honored, wildcard patterns skipped — and hosts from known_hosts, instead of falling back to listing the current directory. (#51)

0.9.0 - 2026-07-10

Changed

• Ctrl+R history search is now a browsable menu: matching is fuzzy (subsequence with word-boundary/consecutive bonuses; space-separated terms must all match) blended with frecency, and the ranked candidates float beside the prompt — matched characters highlighted, selection moved by Ctrl+R/↓ and Ctrl+S/↑, Enter to edit, Cmd+Enter to run outright. An empty query lists the whole history by frecency, so bare Ctrl+R is a "recent & relevant" browser. The classic (reverse-i-search) line stays. (#45)
• History records now carry when the command ran and its exit code: new entries are <ts>\t<exit>\t<cwd>\t<command>, written when the command finishes (zsh INC_APPEND_HISTORY_TIME-style, exit code sniffed from OSC 133;D daemon-side); older formats still load. The Ctrl+R menu shows "ran 3h ago" and a ✗ badge on commands whose last run failed; timestamps from zsh/bash history files are carried over when seeding. (#45)

0.8.0 - 2026-07-10

Added

• Copy on select: an opt-in Settings → Terminal → Clipboard toggle (config key copy_on_select) that copies a mouse selection — drag, double-click word, or triple-click line, over terminal output or the prompt's command editor — to the clipboard the moment the gesture ends, no ⌘C needed. Off by default so a stray selection never overwrites the clipboard. (#34)

Fixed

• The held-⌘ tab-number badges no longer stick on after the window loses key status mid-hold (⌘-Tab, Spotlight, a click into another app). The ⌘ release goes to whatever app is key by then, so the window never saw it; the badges — and any pending reveal — are now dismissed on the activation flip itself.

0.7.0 - 2026-07-10

Added

• Terminal ANSI colors (color0–color15) can now be overridden individually via ansi_colors.* in config.json, layered on top of the active theme preset — with a color picker per slot under Settings → Appearance → ANSI Colors. Malformed values are ignored, and clearing an override falls back to the preset's palette. (#37)

• Font ligatures can now be enabled for terminal text. A new optional font_features config passes OpenType features (e.g. {"calt": true}) through to the renderer, and Settings → Appearance grows a toggle for the common calt/liga pair. Ligatures stay disabled by default for cell-grid safety, and changes hot-apply to open panes. (#38)

Fixed

• Ctrl+L now clears the screen while the prompt-local line editor is active. The readline dispatcher used to swallow it as an unrecognized chord; it now forwards the same form-feed byte the raw terminal path sends, so the shell repaints its prompt as expected. (#36)

0.6.2 - 2026-07-08

Changed

• Context menus and the "+" dropdown now highlight the hovered row with the same soft fill the command palette uses for its selected row, instead of the stock saturated accent that snapped hard against the rest of the UI. The hover text stays at the normal foreground so it reads clearly on the quieter fill.

Fixed

• On Windows, a pane no longer hangs open when its shell exits on its own. Typing exit, pressing Ctrl-D, or a shell crash ends the shell, but ConPTY's output pipe never reports EOF on a natural exit — and tty7 detected a shell's death solely from that EOF — so the pane was left wedged open, dead but visible. A Windows-only monitor now waits on the shell process directly and reports the exit through the same path a Unix read() EOF drives, so the pane closes as it does everywhere else. Closing a tab from the UI was already unaffected; macOS and Linux are unchanged. (#30)

• Nerd Font prompt icons no longer render sliced off on the right. A non-Mono Nerd Font (and the proportional ➜/❯ the OS cascade hands back when nothing in your font list covers them) gives an icon a single-cell advance but draws ink up to ~1.9 cells wide, and tty7 clipped every lone glyph to exactly one cell — severing the overflow into the half-icons and cut-off arrow from the report. A single glyph now paints into a two-cell window, so it renders whole (bleeding into the trailing blank the way iTerm2 and Terminal.app do), bounded at two cells so a stray face can't smear across the row. Pairs with the native powerline separators from #19; Mono Nerd Fonts are unchanged. (#17)

• New tabs and splits no longer stall for seconds while a zsh plugin manager reinstalls itself. tty7 launches zsh through a throwaway ZDOTDIR (so it can layer its shell integration on top of your config), but it used to leave ZDOTDIR pointing at that empty temp dir the whole time — so tools that find their own state via ${ZDOTDIR:-$HOME} (Zim, oh-my-zsh, compinit's .zcompdump) looked in the wrong place and rebuilt from scratch on every pane, e.g. Zim reprinting modules/…: Installed and hanging for ~3s. Each redirector now points ZDOTDIR back at your real config dir while your startup files run, and restores it for the live session, so plugin managers and completion caches resolve correctly and load instantly. As a bonus this also fixes the classic relocated-config layout (a tiny ~/.zshenv that sets ZDOTDIR=~/.config/zsh), which previously loaded your config but silently dropped tty7's integration. (#15)

0.6.1 - 2026-07-08

Fixed

• Tab completion (and other line editing) now stays out of the way over ssh. A remote shell that emits its own prompt marks — fish 4.x on a Linux server, most visibly, which ships OSC 133 on by default — used to engage tty7's local line editor, so Tab ran completion against the local machine's filesystem instead of reaching the remote shell. tty7 now only drives the inline editor while the shell it launched is itself idle at its prompt; whenever a foreground command (ssh, a TUI, a nested shell) owns the terminal, keystrokes pass straight through to it. (#26, follow-up to #18)

0.6.0 - 2026-07-08

Added

• The "+" button now opens a shell picker: tty7 detects the shells installed on this machine (on Unix the login shell, /etc/shells, plus well-known shells found on PATH — fish, nushell, pwsh and friends installed by Homebrew/nix are never registered in /etc/shells; on Windows PowerShell 7, Windows PowerShell, Command Prompt, Git Bash and WSL distributions) and lists them in a dropdown, so opening a tab in a different shell no longer requires editing config.json. The default entry leads the menu, ⌘T / Ctrl+T still opens a default tab in one keystroke, and splitting a pane inherits its shell — a fish tab splits into more fish, not back to the default. Shells picked this way aren't remembered across restarts (restored panes re-attach to their still-running shells anyway).

Changed

• The Windows default shell now prefers PowerShell 7 (pwsh.exe) when installed — probed across Program Files (x64/x86/ARM), the Microsoft Store, scoop, dotnet tools and PATH — and falls back to Windows PowerShell as before. Set shell in config.json to override, as ever.

Fixed

• Powerline prompt separators (powerlevel10k, oh-my-posh, oh-my-zsh) now render pixel-perfect at any font, size and line-height: the eight solid separators (sharp triangles, round caps, slants) are drawn natively as fill paths sized to the exact cell instead of relying on a Nerd Font, so segments meet their backgrounds cleanly with no gaps, narrow wedges or tofu. The bundled Hack font is also appended to every font-fallback chain, so common prompt glyphs (➜, ❯, box drawing) no longer render truncated or missing when no Nerd Font is installed. (#17)
• A URL glued directly to a full-width bracket with no space — e.g. …/pull/343（fix/… → dev） — no longer swallows the bracket text into the link. URL detection now stops at the first non-URL character (a CJK glyph, full-width bracket, arrow or emoji), while interior ASCII parens (Wikipedia-style URLs) are still preserved.
• Fish, nushell, pwsh and other shells installed by Homebrew or nix now appear in the "+" shell picker even when they aren't registered in /etc/shells (which those package managers leave to the user): a curated set of well-known shells is now probed on PATH as a catch-all, after the /etc/shells entries. (#18)
• Upgrading tty7 while an older daemon is still running in the background no longer breaks new tabs. A stale daemon that accepts the connection but can't serve the new client's request is now restarted once and retried automatically; on macOS the GUI also forwards the shell it was launched with to the detached daemon, so panes use the right shell instead of a stale $SHELL inherited from LaunchServices.

0.5.0 - 2026-07-07

Added

• Windows releases now ship an Inno Setup installer (tty7-<version>-windows-x86_64-setup.exe) alongside the portable zip. It installs per-user by default (no admin prompt, with an all-users option), adds a Start Menu shortcut and an "Apps" uninstall entry, and offers an optional desktop icon. Still unsigned, so SmartScreen warns on first launch.
• Startup update check: tty7 asks GitHub once, in the background, whether a newer release has shipped. If so, it pops a one-time "Update available" dialog (once per version — remembered in update.json, so it never nags twice for the same release) and keeps a persistent "Download" prompt in Settings → About. Both open the Releases page; tty7 never downloads or updates itself — you still install by hand. Turn the check off with check_for_updates in config.json or the "Check for updates on launch" toggle in About. A failed or offline check is silent.
• ⌘K (Ctrl+K on Windows/Linux) clears the screen and scrollback — the same "Clear" the right-click menu already offered, now on the keyboard shortcut Terminal.app, iTerm2, and Ghostty users expect. Also available from the command palette, and remappable as ClearScrollback in keybindings.
• ⌘⏎ toggles window fullscreen (new ToggleFullscreen action, also in the View menu and command palette), matching the Ghostty/iTerm2 default. It previously toggled pane maximize — which silently did nothing in a single-pane tab, so the chord felt dead.
• The right-click menu now shows each item's keyboard shortcut. Copy, Paste, Select All, and Find previously showed nothing (they're dispatched inline, with no bound key for the menu to read a hint from) while the other items did, so the menu looked half-labelled. ⌘A / ⌘F stay hint-less on Windows/Linux, where those chords keep their readline meaning.

Changed

• Maximize / restore pane moved from ⌘⏎ to ⌘⇧⏎ (Ghostty's toggle_split_zoom default), making room for fullscreen on the bare chord. An existing ToggleMaximizePane override in keybindings still wins.

Fixed

• Windows: launching tty7 no longer opens a stray console window behind the app. Release builds are now linked with the windows subsystem; debug builds keep the console so println! output stays visible. (#10)
• The right-click "Select All" now matches the ⌘A shortcut: at the prompt it selects the edited command line, otherwise the whole terminal buffer. It previously always selected the whole buffer, so click and keystroke behaved differently at the prompt.
• Ctrl+R reverse-search now accepts plain ASCII keystrokes. The query only took text from the IME commit path, so a non-CJK input source on macOS — and all typing on Linux — was swallowed: the search box opened but ate every key. Reported on V2EX.

0.3.0 - 2026-07-07

Added

• PowerShell shell integration: powershell.exe and pwsh now emit the OSC 133 semantic-prompt marks and OSC 7 cwd that zsh/bash/fish already do, injected via -EncodedCommand after the user's profile loads (their config is never touched). This turns on the inline line editor at the PowerShell prompt — so clicking positions the caret and new tabs/splits inherit the working directory — which is what previously made mouse clicks a no-op at the prompt on Windows.

Fixed

• Typing exit (or Ctrl-D) left a dead "process exited" pane behind instead of closing it. A pane whose shell genuinely ends now closes itself — collapsing its split, or closing the tab when it was the only pane (the last tab falls back to the home page), like every other terminal. A pane that merely lost its daemon connection still stays visible: auto-closing those would silently discard — and kill — sessions that may still be alive daemon-side. Panes that died while detached clean themselves up on the next attach the same way.

• A full-screen TUI dying without restoring the terminal — the canonical case being an ssh session dropping mid-htop/vim — left the pane stranded on the alt screen with a hidden cursor and live mouse reporting: a visible prompt with no cursor anywhere, mouse clicks echoing 0;19;42M-style junk, and broken scrollback. The client now scrubs this residue the moment the shell reports its next prompt (OSC 133): it leaves the stranded alt screen, re-shows the DECTCEM-hidden cursor, and disables stale mouse/focus reporting and kitty keyboard flags — each reset only when its mode is actually set. Reattach self-heals the same way, since the daemon replays the prompt state after the ring.

• Windows shell integration never engaged even for the default shell: detection keyed off portable-pty's get_shell(), which reports %ComSpec% (cmd.exe) regardless of what's actually spawned, so the PowerShell default was mistaken for an unsupported shell. It now resolves to powershell.exe directly.

0.2.0 - 2026-07-04

Added

• Underline styles: undercurl, double, dotted, and dashed underlines render distinctly.
• config.json hot reload — edits apply to the running app without a restart.
• Desktop notifications driven by OSC 9 / OSC 777 escape sequences.
• Kitty keyboard protocol (CSI u progressive enhancement) for TUI apps like Neovim and Helix.
• Shell integration for bash and fish, alongside the existing zsh support.
• Windows support: cross-platform daemon, PowerShell as the default shell, embedded app icon.
• Linux support: builds against gpui's x11/wayland backends, /proc-based foreground cwd + pane-title tracking, Linux CI job, and documented build dependencies.
• Downloadable builds for every platform: the release workflow now packages and uploads all four targets — signed/notarized macOS DMGs (arm64 + x86_64) plus unsigned archives for Windows (.zip) and Linux (.tar.gz), each via its own .github/scripts/bundle-<os> script.
• Settings UI: terminal / appearance / behavior options are configurable from the GUI, with a searchable font-family dropdown and a wider theme gallery.
• Configurable default shell.

Changed

• Project renamed to tty7.
• macOS releases ship as drag-to-Applications DMGs instead of zips, and the Intel build moved to the macos-15-intel runner (macos-13 was retired, which had silently kept x86_64 assets from ever publishing).
• Pixel-smooth scrollback: scrolling carries a sub-line fraction and shifts the paint instead of jumping whole lines.
• Smoother scrolling on dense screens: glyph shaping is batched and wakeups are coalesced.
• CJK-dense screens paint ~2.4× faster: consecutive wide glyphs batch into single shaped runs (two columns per glyph) instead of painting cell-by-cell; the grid snapshot buffer is reused across frames and the selection/search overlay scans are skipped when nothing is highlighted. Release builds now use thin LTO.
• Type-ahead is integrated into the line editor instead of being stranded on zle's line.
• New tabs open next to the active tab instead of at the end.
• Terminal throughput ~12× faster (11 MB cat: ~2.0 s → ~0.16 s; DOOM-fire: ~47 fps → ~920 fps, both at 155×40 on an M1 Pro — now ahead of Alacritty/Ghostty on the same machine): the daemon's replay ring is a VecDeque so a full ring no longer memmoves 8 MiB per ~1 KiB PTY read, and the per-connection writer coalesces queued Output frames (≤256 KiB) so a flood reaches the client as a few large frames instead of thousands of tiny ones. A backpressure gate (4 MiB high-water) pauses the PTY reader while the client catches up, so a runaway yes can't grow daemon memory without bound. TTY7_TRACE=1 prints per-second reader-loop accounting on both sides for future diagnosis.
• Second throughput pass, another ~1.4× on bulk output (11 MB cat: ~160 ms → ~100 ms; sustained plaintext drain 124 → 148 MB/s, vs ~170 MB/s for a raw do-nothing PTY reader on the same machine; DOOM-fire is unchanged — it is producer-bound at ~96 MB/s): the backpressure high-water grows to 16 MiB so a big burst drains at PTY speed while the client parses in its own time; daemon⇄GUI socket buffers grow from macOS's 8 KiB default to 256 KiB; the client applies consecutive Output frames as one batched parser pass (one term-lock + wakeup per burst, latency-free — the batch never waits for unarrived bytes); the shared OSC tokenizer skips Ground/Ignore runs with SIMD memchr; the gate's hot path is a lock-free atomic (previously a Mutex plus an unconditional notify_all per socket write); and the four threads on the interactive output path ask macOS for USER_INTERACTIVE QoS to stay off the efficiency cores (TTY7_NO_QOS=1 opts out).

Fixed

• A long --config-dir path crashed the GUI at startup ("path must be shorter than SUN_LEN"): when <config>/daemon.sock would exceed the OS socket-path limit (104 bytes on macOS), the endpoint now falls back to a short per-user path keyed by a stable hash of the config dir ($XDG_RUNTIME_DIR, else the OS temp dir). Short paths keep the original layout, so existing daemons stay reachable.
• Typing right after a command finished could leave a stray echoed character plus zsh's reverse-video % in the scrollback: the "command finished" mark (OSC 133;D) is now emitted the instant the command exits — prepended ahead of the user's precmd hooks (zsh/bash) — instead of after slow prompt frameworks (oh-my-zsh git status, conda), so the local input editor takes keystrokes back hundreds of milliseconds sooner.
• Typing while a command was still running stranded those keystrokes on zle's line at the next prompt — un-editable and double-drawn under the line editor's overlay. Type-ahead adoption (wipe the shell's line, seed the editor) now runs at every prompt, not just the shell's first, and the wipe waits until zle is actually reading (the live 133;B mark) so it is consumed silently instead of being kernel-echoed into the scrollback as a literal ^U.
• Typing ahead of a fast command left kernel-echoed debris in the scrollback (ls plus zsh's reverse-video %). Reconstructable gap input is now held client-side for up to 150 ms: a command that finishes inside the window hands the keystrokes straight to the line editor with the PTY untouched — zero echo; a longer command (or one reading stdin) gets the bytes released verbatim, so REPLs and password prompts still work.
• fish shell integration silently never installed, so fish users got no prompt marks or cwd tracking.
• Security: pasted clipboard content is stripped of ESC bytes, closing a bracketed-paste escape that could inject auto-executing commands.
• Crash when copying/cutting right after a forward word/line delete left a stale selection anchor.
• Ctrl+Alt+<letter> was indistinguishable from Ctrl+<letter> because the legacy key encoder dropped the Alt ESC prefix.
• Plain Enter/Tab/Backspace were wrongly CSI-u-encoded at the kitty-keyboard DISAMBIGUATE level, which could wedge the shell after a crashed TUI.
• No-op edits (e.g. Backspace at the start of the line) no longer swallow the first undo.
• OSC scanners (daemon-side and notification-side) dropped a well-formed sequence that directly followed an unterminated one.
• Daemon pane teardown is hardened: process-group kill, bounded join, dead panes are reclaimed.
• New shells default to $HOME when launched from the app bundle with cwd /.

0.1.0 - 2026-06-30

Initial release.

• Sessions live in a persistent daemon and survive window close / app restart.
• GPU-rendered terminal grid on gpui, backed by Zed's alacritty_terminal fork.
• Tabs and pane splits (split right/down, maximize, focus movement).
• Command palette with fuzzy search over every action.
• Smart line editing: inline completion, syntax highlighting, history, in-terminal search.
• zsh shell integration (OSC 7 cwd + OSC 133 prompt marks) via a throwaway ZDOTDIR.
• Native macOS light/dark themes that follow the system appearance.
