 #### Added
-- **`nebula ctl orchestrate`** — a strongly typed single-request workflow: a model submits its intent once and the Runtime performs the deterministic control steps locally, bounded by a step count, a byte ceiling and a readiness timeout, with per-workflow `stop`/`continue` error handling.
+- **Deterministic Runtime orchestration** — `nebula ctl orchestrate` accepts one typed request and executes bounded local control steps with workflow-specific `stop`/`continue` failure handling.
+- **Expanded Runtime control APIs** — named-agent operations, process and control-key commands, real command exit status, pane lifecycle events, and a stabilized transport/discovery path are available to automation clients.
+- **Transactional managed-agent worktrees** — agent forks create isolated branches and worktrees, retain stable agent identity, and roll back resources only when failure is confirmed.
+- **Packaged Runtime contract** — the versioned schema, control API documentation, and `nebula-runtime` Skill ship in both the ZIP and installer.
+- **Horizontal title-bar tabs** — top-mode tabs support selection, drag reordering, docking and splitting, plus horizontal auto-scroll while selecting or dragging. Settings now lives in the three-dot menu, and the first tab aligns with the terminal/powerline edge.
+- **SVN integration** — the GPUI repository workflow and status panel now support SVN working copies alongside Git.
+- **SSH failure retry** — both shells show Retry immediately to the left of Close only after a connection failure and replace that failed pane in place.
 
 #### Fixed
-- **The checked-in shell completions match the CLI again** — `ctl orchestrate`, `--gpui` and `--legacy-shell` were missing from the generated bash/fish/zsh scripts.
+- **Second launches reach the resident window** — opening Nebula again hands the request to the running instance and creates the requested tab/window instead of exiting silently. Addresses [#39](https://github.com/Kuddev/nebula/issues/39).
+- **Sogou and other IMEs keep ownership of unmodified text input** — ordinary letters and Space remain on the text-input path so IME composition can be confirmed. Addresses [#43](https://github.com/Kuddev/nebula/issues/43).
+- **WSL keeps the guest's configured default shell** — Nebula no longer forces Bash when launching `wsl.exe`. Addresses [#44](https://github.com/Kuddev/nebula/issues/44).
+- **Ctrl+C is conditional copy again** — with no selection it reaches the PTY; after an explicit copy, the selection is cleared before the next key event. Addresses [#48](https://github.com/Kuddev/nebula/issues/48).
+- **Legacy `user@host:port` SSH targets no longer fail the Windows configuration probe with `11001`** — only the `ssh -G` probe target is normalized to `ssh://user@host:port`; the actual connection destination is preserved.
+- **Codex Shift+Enter is encoded as a Win32 input record** — ConPTY Win32 input mode and DECSET 9001 tracking preserve the modified Enter key.
+- **Background blur can be toggled at runtime** and hidden windows recover correctly when tray support is disabled.
+- **Opacity sliders no longer rebuild fonts, themes, wallpaper textures, or DWM state on every drag event.**
+- **WSL file trees no longer report cold or timed-out reads as empty folders** and the Files panel follows the active local/WSL/SSH pane after switches and manual navigation.
+- **PowerShell startup injection is present before the first prompt** for three-dot launches, powerline-disabled sessions, and alternate profile paths.
+- **Checked-in bash, fish, and zsh completions match the CLI** for `ctl orchestrate`, `--gpui`, and `--legacy-shell`.
+- **Installer fallback and numeric version metadata now follow the application release version.**
 
 #### Improved
-- **The WSL file tree builds from one `find` call** — multiple starting points are batched into a single guest round trip instead of one subprocess per root.
+- **Completion is routed through each pane's filesystem** — local, WSL, and SSH panes fetch candidates from their own environment instead of the host filesystem.
+- **WSL tree enumeration batches starting points into one `find` call** and uses a realistic cold-start timeout; refreshes are event-driven instead of running every four seconds.
+- **Shell injection is selected by shell family** so PowerShell, cmd, Nushell, and fallback shells keep their compatible startup/completion behavior.
+- **Mixed-DPI window dragging coalesces intermediate work** and separates the native move transaction from the final DPI/size commit.
+- **GPUI split-pane chrome and title-bar integration were aligned**, while the sidebar mode and its settings control remain unchanged.
+- **The shell-injected `fmt` command was removed** and the expanded sidebar toggle now uses the legacy shell's softer selected surface.
+- **README Star History rendering was restored** by [@FaintFlower](https://github.com/FaintFlower) in [#49](https://github.com/Kuddev/nebula/pull/49).
 
 ### 简体中文
 
 #### 新增
-- **`nebula ctl orchestrate`** — 强类型单请求编排：模型只提交一次意图，Runtime 在本地完成确定性控制步骤，受步数、字节上限与就绪超时三重约束，并支持按工作流选择 `stop`/`continue` 的错误处理。
+- **确定性的 Runtime 编排** — `nebula ctl orchestrate` 接收一次强类型请求，在本地执行受步数、字节上限和就绪超时约束的控制步骤，并支持按工作流选择 `stop`/`continue` 错误处理。
+- **扩展 Runtime 控制 API** — 新增命名 agent 操作、进程与控制键命令、真实命令退出码、pane 生命周期事件，并稳定了传输与发现路径。
+- **事务式托管 agent worktree** — agent fork 会创建隔离分支与 worktree，保存稳定 agent 身份，并且只在确认失败时回滚本次创建的资源。
+- **随包提供 Runtime 契约** — ZIP 与安装器都包含带版本的 schema、控制 API 文档和 `nebula-runtime` Skill。
+- **水平标题栏标签页** — 顶部模式支持选择、拖拽排序、停靠与分屏，选择或拖拽时可水平自动滚动；设置入口已收进三个点菜单，首个标签与终端/powerline 左边缘严格对齐。
+- **SVN 集成** — GPUI 仓库工作流与状态面板现在除 Git 外也支持 SVN 工作副本。
+- **SSH 失败重试** — 两套界面都只在连接失败后显示“重试”，位置紧邻“关闭”左侧，并在原位替换失败的 pane。
 
 #### 修复
-- **签入的 shell 补全脚本与 CLI 重新同步** — 生成的 bash/fish/zsh 脚本里缺了 `ctl orchestrate`、`--gpui` 与 `--legacy-shell`。
+- **第二次启动会交给驻留窗口处理** — 再次打开 Nebula 会由现有实例创建所需标签/窗口，不再静默退出。对应 [#39](https://github.com/Kuddev/nebula/issues/39)。
+- **搜狗等输入法继续接管未修饰文本输入** — 普通字母与空格保留在 text-input 路径，输入法组合文本可以正常确认。对应 [#43](https://github.com/Kuddev/nebula/issues/43)。
+- **WSL 保留来宾系统配置的默认 shell** — 启动 `wsl.exe` 时不再强制使用 Bash。对应 [#44](https://github.com/Kuddev/nebula/issues/44)。
+- **Ctrl+C 恢复条件复制语义** — 没有选区时按键传给 PTY；明确复制后，在下一个按键事件前清除选区。对应 [#48](https://github.com/Kuddev/nebula/issues/48)。
+- **旧格式 `user@host:port` 不再让 Windows SSH 配置探测报 `11001`** — 只把 `ssh -G` 探测目标规范化为 `ssh://user@host:port`，实际连接目标保持不变。
+- **Codex 的 Shift+Enter 会编码为 Win32 输入记录** — ConPTY Win32 输入模式与 DECSET 9001 跟踪会保留带修饰键的 Enter。
+- **背景模糊开关可在运行时生效**，关闭托盘时也能正确找回之前隐藏的窗口。
+- **拖动不透明度滑块不再逐事件重建字体、主题、壁纸纹理或 DWM 状态。**
+- **WSL 文件树不再把冷启动或超时误报为空目录**；切换 pane 或手动导航后，Files 面板会继续跟随当前本地/WSL/SSH pane。
+- **PowerShell 在第一条提示符前完成启动注入**，覆盖三个点启动、关闭 powerline 和备用 profile 路径。
+- **签入的 bash、fish、zsh 补全脚本与 CLI 重新同步**，补齐 `ctl orchestrate`、`--gpui` 与 `--legacy-shell`。
+- **安装器兜底版本与数字文件版本会跟随应用发布版本。**
 
 #### 改进
-- **WSL 文件树只发一次 `find`** — 多个起点合并成一次来宾往返，不再每个根目录起一个子进程。
+- **补全按 pane 使用各自的文件系统** — 本地、WSL 与 SSH pane 都从自己的环境获取候选，不再错误读取宿主文件系统。
+- **WSL 文件树把多个起点合并成一次 `find`**，采用符合冷启动实际的超时，并改为事件驱动刷新，不再每四秒全量扫描。
+- **按 shell 家族选择注入逻辑**，让 PowerShell、cmd、Nushell 和通用 fallback 保持各自兼容的启动/补全行为。
+- **混合 DPI 窗口拖动会合并中间更新**，原生移动事务与最终 DPI/尺寸提交彼此分离。
+- **GPUI 分屏边框与标题栏整合已对齐**，侧边栏模式及其设置按钮保持不变。
+- **移除 shell 注入的 `fmt` 命令**，展开的侧栏切换按钮改用旧界面更柔和的选中色。
+- **README Star History 图表已恢复**，由 [@FaintFlower](https://github.com/FaintFlower) 在 [#49](https://github.com/Kuddev/nebula/pull/49) 中贡献。

 ## English
 
-### Fixed
-
-- Fixed Codex treating Shift+Enter as ordinary Enter in Nebula on Windows. The
-  terminal now enables ConPTY Win32 input mode, tracks DECSET 9001, and encodes
-  the corresponding Win32 key records.
-- Fixed the installer's fallback and numeric version metadata still identifying
-  old 0.6.0 builds instead of the current 0.9.0 application version.
-- Fixed PowerShell sessions created from the three-dot shell menu, and sessions
-  with Powerline disabled, losing Nebula's OSC prompt/command state until the
-  first interactive conversation. The OSC bridge is now installed before the
-  first prompt so Codex/CLI detection and the right-side activity state are
-  available immediately.
-- Fixed PowerShell profiles created through the alternate profile path missing
-  the Nebula command-completion integration.
-- Disabled the `fmt` command from Nebula's shell-injected command surface.
-- Fixed the GPUI Windows background-blur switch doing nothing at runtime. The
-  window effects were applied inside `handle.update` while that same window was
-  already borrowed by the enclosing update, so the call always failed with
-  `window not found` and the error was discarded — blur only ever took effect at
-  startup, and once on it could not be turned off. Effects are now applied on a
-  deferred pass and update failures are logged.
-- Fixed dragging the opacity sliders stuttering badly. Dragging no longer
-  reloads settings from disk, rebuilds every terminal's fonts and palette,
-  rebuilds the whole theme, re-bakes the wallpaper texture, or round-trips to
-  DWM on every event; it updates the shell alpha directly and persists once
-  after the drag settles. The blocking `DwmFlush` was removed and window-level
-  blur is only touched when the blur state actually changes.
-- Fixed the WSL file tree showing "此目录为空" for guest directories. A fresh
-  `wsl.exe -d <distro> -- find` call takes about 7.5s on its cold path even when
-  the same distribution already has an interactive terminal running, so the 6s
-  budget always expired on the first snapshot, the worker was killed, and the
-  empty result was rendered as an empty directory. The budget is now 20s.
-- The Files panel no longer re-scans the tree on a timer. It previously rebuilt
-  the whole snapshot (a WSL subprocess plus three git subprocesses) every 4
-  seconds, which on WSL left the panel flipping between "正在读取目录…" and an
-  empty list. Refreshes are now driven by directory changes, the refresh button,
-  and finished git operations only.
-- Fixed windows staying hidden when the tray was disabled while they were
-  minimized to it. The reveal path applied its effect inside `handle.update` on
-  an already-borrowed window, so it always failed silently while
-  `window_hidden` had already been cleared — leaving an app with no window and
-  no tray icon that could not restore itself.
-- Fixed the shared Files panel losing the active pane after tab/pane switches
-  or manual tree navigation. WSL `/mnt/<drive>` paths map to the host drive,
-  while `/`, `/home`, `/etc`, and other guest paths are enumerated inside the
-  selected distribution. Directory rows are published before the slower WSL
-  VCS probe, refresh resumes following the active pane, and timed-out workers
-  can no longer disable later refreshes.
-
-### Improved
-
-- Added a default-selected installer task that adds Nebula to the current
-  user's PATH. The installer also registers `nebula.exe` with Windows App Paths
-  for Win+R, preserves the Explorer directory context menus, and removes only
-  its own PATH entry during uninstall.
-- Shell injection is now selected by shell family. PowerShell uses its own
-  startup/status path; `cmd.exe` uses only the compatible minimal status path;
-  Nushell keeps its native completion behavior and is not replaced by Nebula's
-  completion script; other shells use the fallback OSC path where supported.
-- Improved Windows mixed-DPI dragging between monitors by separating the
-  native move transaction from the final DPI/size commit. The Windows 11
-  backend must use the native `WM_DPICHANGED` target rectangle, while the
-  Windows 10 compatibility reposition path remains gated to older builds.
-- Improved cross-monitor drag performance by coalescing intermediate DPI,
-  physical-size, font, and UI updates until the native drag settles. Ordinary
-  native messages remain on the fast path.
-- Matched the expanded sidebar toggle's selected background to the softer
-  surface color used by the legacy shell without changing other selected
-  buttons globally.
+No unreleased changes yet.
 
 ## 中文
 
-### 修复
-
-- 修复 Windows 下 Codex 把 Shift+Enter 当作普通 Enter 的问题。终端现在启用
-  ConPTY Win32 输入模式、跟踪 DECSET 9001，并编码对应的 Win32 按键记录。
-- 修复安装器兜底版本与数字文件版本仍显示旧 0.6.0、没有跟随当前 0.9.0
-  应用版本的问题。
-- 修复通过三个点创建的 PowerShell，或关闭 Powerline 后的 PowerShell，在
-  第一次实际对话前丢失 Nebula OSC 提示符/命令状态的问题。现在启动阶段就
-  安装 OSC 桥接，因此 Codex/CLI 识别和右侧活动状态会在第一条提示符出现
-  时可用，不需要先发送一轮对话。
-- 修复通过备用 profile 路径创建的 PowerShell 没有命令补齐的问题。
-- 禁用 shell 注入命令面板中的 `fmt` 命令。
-- 修复 GPUI Windows 壳的背景模糊开关在运行中点了没反应的问题。窗口视效原先在
-  `handle.update` 里应用，而那一刻这个窗口已经被外层 update 借出，调用必然返回
-  `window not found`，错误又被丢弃——于是模糊只在启动时生效，一旦开着就再也
-  关不掉。现在改为延迟一帧统一应用，且 update 失败会留日志。
-- 修复拖动不透明度滑块严重卡顿的问题。拖拽过程不再每个事件都重新读设置文件、
-  重建每个终端的字体与调色板、重建整套主题、重烘焙壁纸纹理、以及和 DWM 往返；
-  改为直接更新壳色 alpha，停手之后落盘一次。阻塞式 `DwmFlush` 已移除，窗口级
-  模糊只在模糊态真的改变时才动。
-- 修复共享 Files 面板在切换 tab/pane 或手动浏览目录后不再跟随当前 pane 的
-  问题。WSL `/mnt/<盘>` 映射到宿主盘，`/`、`/home`、`/etc` 等来宾路径则在
-  对应发行版内枚举；目录行会先于较慢的 WSL VCS 探测发布，刷新按钮会恢复
-  跟随当前 pane，WSL 工人超时也不会再让后续刷新永久失效。
-
-### 改进
-
-- 安装器新增默认勾选的当前用户 PATH 任务，并通过 Windows App Paths 注册
-  `nebula.exe` 供 Win+R 直接启动；资源管理器目录右键菜单继续随包提供，卸载
-  时只移除安装器自己加入的 PATH 条目。
-- 按 shell 家族选择注入逻辑：PowerShell 使用专用启动/状态路径；`cmd.exe`
-  只使用兼容的最小状态路径；Nushell 保留自身原生命令补齐，不被 Nebula
-  的补齐脚本替换；其他 shell 在支持时使用通用 OSC 回退路径。
-- 改进 Windows 混合 DPI 多显示器拖动：把原生拖动阶段与最终 DPI/尺寸提交
-  分离；Windows 11 使用原生 `WM_DPICHANGED` 目标矩形，Windows 10 的兼容
-  重定位逻辑只对旧版本生效。
-- 改进跨显示器拖动性能：中间产生的 DPI、物理尺寸、字体和 UI 更新合并到
-  原生拖动结束后执行，普通系统消息仍走快速路径。
-- 左上角侧栏折叠按钮展开时改用与旧壳一致的柔和 surface 选中色，不全局
-  改动其他 selected 按钮的主题状态。
-
-## Verification
-
-The PowerShell/OSC changes need first-prompt checks for all profile creation
-routes. The mixed-DPI change still requires a real Windows two-monitor matrix,
-including Windows 11 150% -> 125% and the reverse direction. A compile check
-alone is not sufficient to claim that the physical monitor seam is fixed. The
-WSL changes still require guest-path checks for both `/mnt/<drive>` and native
-Linux repositories, and the blur change requires a live Windows DWM toggle
-check in both directions.

+# Nebula Terminal 1.2.0
+
+Nebula Terminal 1.2.0 expands the Runtime control surface, adds horizontal title-bar tabs and SVN support, and concentrates this cycle's Windows, WSL, SSH, IME, and GPUI reliability work into one release.
+
+Nebula Terminal 1.2.0 扩展了 Runtime 控制能力，加入水平标题栏标签页与 SVN 支持，并集中交付本周期的 Windows、WSL、SSH、输入法与 GPUI 稳定性改进。
+
+## English
+
+### Highlights
+
+- Horizontal title-bar tabs support selection, drag reordering, docking, split creation, and horizontal auto-scroll. In top mode, Settings now lives in the three-dot menu and the first tab starts exactly at the terminal/powerline left edge; sidebar mode is unchanged.
+- The Runtime can orchestrate typed workflows, control named agents and processes, report real exit status and pane lifecycle events, and create transactional managed-agent worktrees.
+- Completion and file-tree work now follow each pane's real local, WSL, or SSH filesystem context.
+- This release addresses the resident second-launch, Sogou IME, WSL default-shell, and conditional Ctrl+C Copy reports tracked in Issues #39, #43, #44, and #48. The mapping below keeps those fixes traceable while the Issues remain open for user verification.
+
+### Added
+
+- Added `nebula ctl orchestrate`, a typed single-request workflow whose deterministic local steps are bounded by step count, byte ceiling, and readiness timeout, with per-workflow `stop`/`continue` failure behavior.
+- Added named-agent control, process and control-key APIs, real command exit status, and pane lifecycle events to the Runtime contract.
+- Added isolated, transactional worktree creation for managed agents, including stable branch/path identity and failure-aware rollback.
+- Added the versioned Runtime schema, control API documentation, and `nebula-runtime` Skill to the ZIP and installer payloads.
+- Added the horizontal title-bar tab layout with drag reorder, dock/split targets, and drag/selection auto-scroll.
+- Added SVN working-copy detection and repository status/workflow support to the GPUI shell.
+- Added a failure-only SSH Retry action immediately to the left of Close in both the legacy and GPUI shells. Retry atomically replaces only the failed pane with the same destination.
+
+### Fixed
+
+- Fixed a second Nebula launch silently disappearing while a resident instance was running. The launch request is now handed to that instance, which creates and focuses the requested tab/window. Addresses [#39](https://github.com/Kuddev/nebula/issues/39).
+- Fixed unmodified letters and Space bypassing the Windows text-input path, allowing Sogou and other IMEs to confirm composition normally. Addresses [#43](https://github.com/Kuddev/nebula/issues/43).
+- Fixed WSL launches forcing Bash instead of honoring the guest account's `/etc/passwd` default shell. Addresses [#44](https://github.com/Kuddev/nebula/issues/44).
+- Fixed Ctrl+C Copy consuming the key when there is no selection and repeatedly copying a stale selection. No selection now propagates Ctrl+C to the PTY; an explicit copy clears selection before the next key event. Addresses [#48](https://github.com/Kuddev/nebula/issues/48).
+- Fixed legacy `user@host:port` SSH destinations failing the Windows `ssh -G` configuration probe with resolver error `11001`. Only the probe target is normalized to `ssh://user@host:port`; the real connection destination is unchanged.
+- Fixed Codex treating Shift+Enter as ordinary Enter by enabling ConPTY Win32 input, tracking DECSET 9001, and encoding the corresponding Win32 key record.
+- Fixed runtime background-blur toggling and the related path that could leave a window hidden after tray support was disabled.
+- Fixed opacity sliders rebuilding fonts, terminal palettes, themes, wallpaper textures, and DWM state on every drag event.
+- Fixed WSL cold-start/timeout failures being rendered as empty directories. The Files panel now keeps following the active local/WSL/SSH pane after tab changes, pane changes, and manual navigation.
+- Fixed PowerShell sessions opened from the three-dot menu or with Powerline disabled missing OSC command state before their first interaction.
+- Fixed alternate PowerShell profile launches missing Nebula command completion.
+- Fixed checked-in bash, fish, and zsh completion scripts omitting `ctl orchestrate`, `--gpui`, and `--legacy-shell`.
+- Fixed the installer's fallback and numeric file-version metadata lagging behind the application version.
+
+### Improved
+
+- Routed completion requests through each pane's own local, WSL, or SSH filesystem provider.
+- Batched WSL file-tree starting points into one guest `find` call, increased the cold-start budget, and replaced the four-second polling scan with event-driven refreshes.
+- Selected shell injection by shell family: PowerShell keeps its full integration, cmd uses its compatible minimal status path, Nushell keeps native completion, and other shells use the supported OSC fallback.
+- Stabilized Runtime transport/discovery and kept pane/window ownership explicit across the agent-control path.
+- Improved mixed-DPI dragging by separating native move handling from the final DPI/size commit and coalescing intermediate work.
+- Matched split-pane chrome and title-bar integration in GPUI, moved only top-mode Settings into the three-dot menu, and preserved the sidebar-mode Settings button.
+- Removed the shell-injected `fmt` action and aligned the expanded sidebar toggle with the legacy shell's softer selected surface.
+- Restored the README Star History chart through [#49](https://github.com/Kuddev/nebula/pull/49).
+
+## 中文
+
+### 重点更新
+
+- 水平标题栏标签页支持选择、拖拽排序、停靠、创建分屏与水平自动滚动。顶部模式的设置入口已收进三个点菜单，首个标签与终端/powerline 左边缘严格对齐；侧边栏模式不变。
+- Runtime 新增强类型工作流编排、命名 agent/进程控制、真实退出码、pane 生命周期事件与事务式托管 agent worktree。
+- 补全与文件树会跟随每个 pane 的真实本地、WSL 或 SSH 文件系统上下文。
+- 本版处理了 Issue #39、#43、#44、#48 对应的驻留进程二次启动、搜狗输入法、WSL 默认 shell 与条件式 Ctrl+C 复制问题。下方保留明确定位，Issue 暂不自动关闭，等待用户实机验证。
+
+### 新增
+
+- 新增 `nebula ctl orchestrate` 强类型单请求工作流：本地确定性步骤受步数、字节上限与就绪超时约束，并支持按工作流配置 `stop`/`continue` 失败行为。
+- Runtime 契约新增命名 agent 控制、进程/控制键 API、真实命令退出码与 pane 生命周期事件。
+- 新增隔离、事务式的托管 agent worktree 创建，保留稳定的分支/路径身份，并按可确认的失败边界回滚。
+- ZIP 与安装器新增带版本的 Runtime schema、控制 API 文档和 `nebula-runtime` Skill。
+- 新增水平标题栏标签布局，以及拖拽排序、停靠/分屏目标和拖拽/选择自动滚动。
+- GPUI 界面新增 SVN 工作副本识别、仓库状态与操作工作流。
+- 旧界面和 GPUI 界面都新增仅在 SSH 连接失败后出现的“重试”按钮，位置紧邻“关闭”左侧；重试只会在原位原子替换失败的 pane。
+
+### 修复
+
+- 修复已有驻留实例时第二次启动 Nebula 会静默消失的问题。启动请求现在会交给驻留实例，由它创建并聚焦所需标签/窗口。对应 [#39](https://github.com/Kuddev/nebula/issues/39)。
+- 修复普通字母与空格绕过 Windows text-input 路径的问题，搜狗等输入法现在可以正常确认组合文本。对应 [#43](https://github.com/Kuddev/nebula/issues/43)。
+- 修复 WSL 启动时强制使用 Bash、忽略来宾账号 `/etc/passwd` 默认 shell 的问题。对应 [#44](https://github.com/Kuddev/nebula/issues/44)。
+- 修复没有选区时 Ctrl+C 被复制动作吞掉，以及旧选区导致反复复制的问题。无选区时 Ctrl+C 会传给 PTY；明确复制后会在下一个按键事件前清除选区。对应 [#48](https://github.com/Kuddev/nebula/issues/48)。
+- 修复旧格式 `user@host:port` 让 Windows `ssh -G` 配置探测报解析错误 `11001`。只有探测目标会规范化为 `ssh://user@host:port`，实际连接目标保持不变。
+- 修复 Codex 把 Shift+Enter 当作普通 Enter：启用 ConPTY Win32 输入、跟踪 DECSET 9001，并编码相应的 Win32 按键记录。
+- 修复运行时背景模糊开关无效，以及关闭托盘后窗口可能继续隐藏的同源问题。
+- 修复不透明度滑块每次拖动事件都重建字体、终端色表、主题、壁纸纹理与 DWM 状态的问题。
+- 修复 WSL 冷启动/超时被渲染成空目录的问题；切换标签、pane 或手动导航后，Files 面板会继续跟随当前本地/WSL/SSH pane。
+- 修复从三个点菜单启动或关闭 Powerline 的 PowerShell 在第一次交互前缺少 OSC 命令状态的问题。
+- 修复备用 PowerShell profile 启动路径缺少 Nebula 命令补全的问题。
+- 修复签入的 bash、fish、zsh 补全脚本缺少 `ctl orchestrate`、`--gpui` 与 `--legacy-shell` 的问题。
+- 修复安装器兜底版本与数字文件版本没有跟随应用版本的问题。
+
+### 改进
+
+- 补全请求现在通过每个 pane 自己的本地、WSL 或 SSH 文件系统提供器执行。
+- WSL 文件树会把多个起点合并成一次来宾 `find`，延长冷启动预算，并以事件驱动刷新代替每四秒轮询扫描。
+- 按 shell 家族选择注入：PowerShell 保留完整集成，cmd 使用兼容的最小状态路径，Nushell 保留原生补全，其他 shell 使用受支持的 OSC fallback。
+- 稳定 Runtime 传输与发现逻辑，并在 agent 控制路径中明确维护 pane/window 所属关系。
+- 改进混合 DPI 拖动：原生移动处理与最终 DPI/尺寸提交分离，中间更新合并执行。
+- 对齐 GPUI 分屏边框与标题栏整合；只移动顶部模式的设置入口，侧边栏模式设置按钮保持不变。
+- 移除 shell 注入的 `fmt` 动作，展开的侧栏切换按钮改用旧界面更柔和的选中色。
+- 通过 [#49](https://github.com/Kuddev/nebula/pull/49) 恢复 README Star History 图表。
