## 0.2.1 — 2026-07-11
## 0.2.1 - 2026-07-11
### 🐛 Fixes
### Fixes / 修复
- **Per-pane event routing** — window event batches were resolved to a single
target pane: typing while a background tab's program (a build, `codex`, a
`tail`) was printing could leak the keystrokes into that tab's PTY, and
terminal query answers (cursor-position / device-attribute reports) could
land in the wrong shell and appear as stray `[10…`-style characters in the
input line. Terminal events now route to their source pane and keyboard /
mouse input always goes to the focused pane; events for an already-closed
pane are dropped instead of stalling the batch.
- **CJK text in chrome rendering** — the string renderer consumed a phantom
"spacer" after every wide glyph, swallowing every second character of
CJK strings in the inline ghost hint (`资料` → `资`…), HUD text and link
previews. It now lays glyphs out by display width and clips at the row
edge instead of bleeding past it.
- **History capture for wrapped prompts** — the prompt line is reconstructed
across soft-wrapped rows (long CJK paths wrap fast at two columns per
char) and snapshotted straight off the grid at Enter time; when the grid
read fails the line is no longer taken from the desync-prone keystroke
buffer, so spliced garbage can't enter the ghost-hint history anymore.
- **`git.exe` close-confirmation noise** — Nebula's own prompt integration
spawns `git` on every prompt render, and the close-confirmation snapshot
routinely caught one mid-flight, blocking tab close with a modal. `git.exe`
is now whitelisted as stateless plumbing.
- **Process lingering after window close** — `ClosePseudoConsole` blocks
until the console host flushes its remaining output; once teardown began
nothing drained the pipe, so an output burst deadlocked the close and left
`nebula.exe` running in Task Manager. Teardown now terminates the shell
tree first and hands conout to a detached drain thread.
- **ConPTY sideload hygiene** — `conpty.dll` is loaded only by absolute path
from the executable's directory, and only when `OpenConsole.exe` sits
beside it, so the pre-primed DA1 handshake answer can no longer leak into
the shell as typed input when the bundled host is missing. A failed
`ResizePseudoConsole` now logs a warning instead of aborting the process.
- **Per-pane event routing** — window event batches previously resolved to one target pane, allowing output from a background tab to misroute keyboard input or terminal query replies. Events now route to their source pane, user input always targets the focused pane, and events for closed panes are dropped.
**中文：** 修复逐 pane 事件路由：过去窗口事件批次只解析到单一 pane，后台标签输出可能导致键盘输入或终端查询回复发往错误 PTY；现在事件按来源 pane 路由，用户输入始终进入焦点 pane，已关闭 pane 的事件直接丢弃。
- **CJK text in chrome rendering** — removed the phantom spacer consumed after every wide glyph, which previously swallowed alternating CJK characters in ghost hints, HUD text, and link previews.
**中文：** 修复 chrome 中的 CJK 文本渲染：移除宽字符后的虚假 spacer，避免幽灵提示、HUD 和链接预览隔字丢失。
- **History capture for wrapped prompts** — prompt text is reconstructed across soft-wrapped rows and snapshotted from the grid on Enter, preventing desynchronized keystroke buffers from polluting history.
**中文：** 修复换行 prompt 的历史捕获：命令会跨软换行重建，并在按下 Enter 时直接从网格快照，避免失同步的按键缓冲污染历史。
- **`git.exe` close-confirmation noise** — Nebula's short-lived prompt helper is treated as stateless plumbing and no longer blocks tab closure with a busy-process dialog.
**中文：** 修复 `git.exe` 触发关闭确认的问题：Nebula prompt 的短生命周期 git 辅助进程现在视为无状态工具，不再阻止标签页关闭。
- **Process lingering after window close** — teardown now terminates the shell tree first and drains ConPTY output on a detached thread, preventing `ClosePseudoConsole` deadlocks.
**中文：** 修复窗口关闭后进程残留：销毁流程先终止 Shell 进程树，再由独立线程排空 ConPTY 输出，避免 `ClosePseudoConsole` 死锁。
- **ConPTY sideload hygiene** — `conpty.dll` is loaded only by absolute path when its matching `OpenConsole.exe` is present; failed resize calls now log warnings instead of aborting.
**中文：** 改进 ConPTY side-load：仅在配套 `OpenConsole.exe` 存在时通过绝对路径加载 `conpty.dll`；resize 失败改为记录警告而非终止进程。
### 🧹 Housekeeping
### Housekeeping / 工程维护
- Third-party license attribution consolidated into `THIRD-PARTY-NOTICES`;
reference-test fixtures renamed after the behaviour they cover.
- **License and fixtures** — consolidated third-party attribution into `THIRD-PARTY-NOTICES` and renamed reference fixtures after the behavior they cover.
**中文：** 将第三方许可归集到 `THIRD-PARTY-NOTICES`，并按实际行为重新命名参考测试 fixture。

## 0.1.0 — 2026-07-07
## 0.1.0 - 2026-07-07
Nebula Terminal 的第一个公开版本 / First public release.
Nebula Terminal's first public release.
### 🤖 AI integration
Nebula Terminal 的第一个公开版本。
- **Real brand marks in the sidebar** — Anthropic starburst for `claude`,
OpenAI blossom for `codex` (textured quads, theme-tinted); Nerd Font icons
for `gemini`, `copilot`, `cursor`, `aider`, `git`, `vim`, `cargo` and more.
- **Live turn state, wired to the source** — Claude Code hooks / Codex notify
invoke the bundled `nebula-hook.exe` (dependency-free), which forwards
typed events over a named pipe: prompt submitted → sidebar spinner; turn
finished → dot + toast; input needed → toast with the actual message text.
No shell integration required.
- **Click-to-focus toasts** — activating a notification surfaces the window,
switches to the raising tab and focuses the raising split.
- **Zero-setup & self-healing** — hook entries install on first boot, heal
if an external config switcher wipes them (a config-directory watcher
re-applies them), and are scoped by environment variables so claude in
other terminals is untouched. `nebula setup-ai [--remove]`,
`nebula notify-test` diagnostics.
- **Chain mode for codex** — a pre-existing notifier in codex's single
`notify` slot keeps firing (`--chain` wrapping), never evicted.
- **Fallback signals** — OSC 133 command tracking + BEL cover every other
CLI: long commands toast on completion with their duration.
### AI Integration / AI 集成
### ♻️ Sessions that survive
- **Real brand marks in the sidebar** — renders the Anthropic starburst for `claude`, the OpenAI blossom for `codex`, and Nerd Font icons for other common developer tools.
**中文：** 侧栏为 `claude` 显示 Anthropic 星芒、为 `codex` 显示 OpenAI 花结，并为其他常见开发工具显示 Nerd Font 图标。
- **Live turn state** — Claude Code hooks and Codex notify call the dependency-free `nebula-hook.exe`, forwarding prompt, completion, and input-needed events over a named pipe.
**中文：** Claude Code hooks 和 Codex notify 调用无依赖的 `nebula-hook.exe`，通过命名管道转发提交、完成和等待输入事件。
- **Click-to-focus notifications** — activating a toast raises the window, selects the originating tab, and focuses the originating split.
**中文：** 点击通知会前置窗口、选择来源标签页并聚焦来源分屏。
- **Zero setup and self-healing** — hook entries install automatically, recover after external configuration rewrites, remain scoped to Nebula, and can be removed with `nebula setup-ai --remove`.
**中文：** hook 条目自动安装，可在外部配置重写后自愈，仅作用于 Nebula，并可通过 `nebula setup-ai --remove` 移除。
- **Codex chain mode** — wraps an existing Codex notifier instead of replacing it.
**中文：** Codex chain 模式会包装已有 notifier，而不是覆盖它。
- **Fallback signals** — OSC 133 and BEL cover other CLIs and report long-command completion with duration.
**中文：** OSC 133 和 BEL 为其他 CLI 提供兜底，并在长命令结束时报告耗时。
- **Session residency** — closing a window detaches its tabs into the
resident process; PTYs (running `claude`, builds, SSH) never stop.
Relaunch re-attaches: same processes, same scrollback.
- **Cold restore** — tab layout and per-tab working directories restore from
a 1 Hz autosaved snapshot after reboot/crash, with crash-loop protection.
- **Single instance** — a second launch hands over to the resident process.
### Persistent Sessions / 会话保活
### 🎨 Interface
- **Session residency** — closing a window detaches its tabs while PTYs continue running; relaunching reattaches to the same processes and scrollback.
**中文：** 关闭窗口仅分离标签页，PTY 继续运行；再次启动可接回相同进程和滚屏内容。
- **Cold restore** — autosaved tab layout and working directories restore after reboot or crash, with crash-loop protection.
**中文：** 重启或崩溃后可从自动快照恢复标签布局和工作目录，并带崩溃循环保护。
- **Single instance** — subsequent launches hand off to the resident process.
**中文：** 后续启动会交给常驻进程处理，保持单实例。
- **Seven-theme skin system** — Nebula plus three matched light/dark pairs
(Silver Light / Steel Dark, Limestone / Coal Dark, Linen Light / Moss
Dark); one token system drives chrome, prompt, dialogs; persisted and
hot-reloadable.
- **Sidebar tabs & splits** — drag to reorder, drag into the terminal area to
dock as a split; unfocused panes dim instead of growing borders; zoomable
panes; CJK-aware chrome text.
- **Quick terminal** — global hotkey drops a Quake-style overlay with a slide
animation.
- **In-app settings panel** — themes, background image & opacity, shell,
completion behavior; grouped glass panels with true scissor clipping.
- **Command palette, resize HUD, auto-hiding scrollbar, visual bell.**
- **Inline images** — OSC 1337 protocol, lazily uploaded, anchored to
scrollback rows.
- **Welcome page** — fastfetch-style system intro on new tabs.
### Interface / 界面
### ⚡ Performance & correctness
- **Seven-theme skin system** — one token system drives seven light/dark themes across chrome, prompts, and dialogs, with persistence and hot reload.
**中文：** 一套设计 token 驱动七种明暗主题，覆盖 chrome、prompt 和对话框，并支持持久化与热重载。
- **Sidebar tabs and splits** — supports tab reordering, drag-to-dock splits, dimmed unfocused panes, zoom, and CJK-aware chrome text.
**中文：** 支持标签排序、拖拽停靠分屏、非焦点 pane 变暗、pane 缩放和 CJK-aware chrome 文本。
- **Quick terminal** — provides a global-hotkey Quake-style terminal with slide animation.

- **Inline images** — supports OSC 1337 images with lazy upload and scrollback anchoring.
**中文：** 支持 OSC 1337 内联图片、延迟上传和滚屏锚定。
- **Welcome page** — adds a fastfetch-style system introduction for new tabs.
**中文：** 新标签页提供 fastfetch 风格的系统欢迎信息。
- **Modern ConPTY host side-loaded** (`conpty.dll` + `OpenConsole.exe`,
MIT-licensed from microsoft/terminal) with the DA1 handshake pre-primed so
a new tab doesn't stall on that round-trip, and resizing no longer smears
full-screen TUIs into scrollback. `openconsole = false` falls back to the
in-box host.
- **Coalesced interactive resizing** — the PTY learns its final size once per
drag; rendering is damage-tracked.
- **Boot instrumentation** — `NEBULA_BOOT_TRACE=1` prints a per-stage timing
trace.
- **Native notifications done right** — WinRT toasts under a registered
`Nebula` app identity (icon included), taskbar flash, global toast
throttle; delivery isolated on a worker thread so a slow notification stack
can never stall rendering.
### Performance And Correctness / 性能与正确性
### 🐚 Shell experience
- **Modern ConPTY host** — bundles `conpty.dll` and `OpenConsole.exe`, pre-primes the DA1 handshake, improves resize behavior, and retains an in-box fallback.

**中文：** 交互式 resize 在拖动结束后一次性通知 PTY，同时继续使用 damage tracking 渲染。
- **Boot instrumentation** — `NEBULA_BOOT_TRACE=1` reports per-stage startup timing.
**中文：** `NEBULA_BOOT_TRACE=1` 可输出逐阶段启动耗时。
- **Native notifications** — WinRT toasts use a registered Nebula identity, taskbar flashing, throttling, and a worker thread that cannot block rendering.
**中文：** WinRT 通知使用注册的 Nebula 身份、任务栏闪烁和全局限流，并在独立线程运行以避免阻塞渲染。
- **Fish-style ghost completions** — dim inline suggestions from persistent
JSONL history and filesystem paths; accepted with `→` / `Tab`.
- **Built-in themed powerline prompt** — git branch + clock for PowerShell
and Git Bash, zero plugins; prompt palette follows the app theme.
- **Quality-of-life input fixes** — unquoted `cd D:/Program Files` works,
bare `$env:KEY=value` auto-quotes, `ls` gains colors and OSC 8 clickable
hyperlinks.
- **OSC coverage** — 7 / 8 / 9 / 9;9 / 133 / 1337 (cwd, hyperlinks,
notifications, semantic prompts, images).
### Shell Experience / Shell 体验
