 ### English
 
@@ -20,29 +20,68 @@ Every release entry is provided in English and Simplified Chinese.
 - Fixed Windows terminal focus consuming `Alt+F4` and `Alt+Space`. `Alt+F4` now uses the normal window-close flow, and `Alt+Space`, followed by `N`, uses the system menu to minimize the window.
 - Fixed the top Settings tab disappearing when switching to another tab. It now remains available until explicitly closed, including when tabs overflow or the tab layout changes.
 - Fixed `Alt+1–9` and `Ctrl+1–9` tab shortcuts losing priority to terminal input. They now work while a terminal or CLI has focus and respect custom shortcut changes without restarting.
+- Fixed WSL filename search failing when the directory path contains spaces or shell punctuation. Cancelling a search stops its own directory scan.
+- Aligned macOS native window controls with the sidebar and Settings buttons, and preserved their reserved space in the top tab layout. Window controls follow the system appearance. Contributed by [@WilliamWang1721](https://github.com/WilliamWang1721) in [#114](https://github.com/Kuddev/pebrel/pull/114).
+- Fixed the Git drawer retaining Chinese labels when the application resolves to English. Controls, history timestamps and application notices follow the selected language; switching languages preserves the commit draft and text selection. Contributed by [@gao-jian-bin](https://github.com/gao-jian-bin) in [#118](https://github.com/Kuddev/pebrel/pull/118).
+- Fixed explicitly configured terminal selection text colors being ignored. Themes without their own selection foreground preserve that setting; themes with an explicit foreground retain their precedence. Contributed by [@Aschenbath](https://github.com/Aschenbath) in [#125](https://github.com/Kuddev/pebrel/pull/125).
 
 #### Improved
 
+- Reduced file browsing and filename-search memory use by starting recursive searches only when a query is entered, reusing a bounded cache and streaming paths beyond that cache. Repeated panel use releases obsolete results and cancels superseded searches. Case, whole-word and regular-expression options remain available, with visible feedback for incomplete searches and errors.
+- Reduced background-image memory use with bounded image loading and reuse while resizing the window. Replacing an image releases the previous resources; extended backgrounds retain their fit, alignment and text readability.
 - Replaced the low-resolution Claude Code icon with artwork exported from SVG at 1024 pixels, and prepared Agent icons at their display size for smoother tab edges.
 
+Windows packages include a Pebrel installer and portable ZIP. Linux x64 packages and macOS Apple Silicon/Intel DMGs retain their Preview designation. macOS requires version 14 or later. Molecular structure rendering remains disabled.
+
 ### 中文
 
 #### 新增
 
-- 在“设置 → 交互”中加入“焦点跟随鼠标”，默认关闭；在“设置 → 外观”中加入“调暗非活动窗格”，默认开启。两项设置均即时生效。
-- Shell 启动菜单新增右键操作，可设为默认 Shell；Windows 下还可在新的管理员 Pebrel 窗口内打开所选 Shell。
-- SSH 启动菜单新增“连接、编辑、删除”右键操作；删除沿用已有的确认与撤销流程。
-- 新增 Trae CLI 识别与标签图标，并为 Oh My Pi 加入独立图标。

 #### 修复
 
-- 修复 Windows 终端获得焦点时吞掉 `Alt+F4` 和 `Alt+Space` 的问题。`Alt+F4` 现在进入正常窗口关闭流程，`Alt+Space` 后按 `N` 可通过系统菜单最小化窗口。
-- 修复顶部设置标签在切换到其他标签后消失的问题。现在只有主动关闭才会移除，标签溢出或切换标签布局时也会保留。
-- 修复 `Alt+1–9` 和 `Ctrl+1–9` 标签快捷键优先级低于终端输入的问题。终端或 CLI 获得焦点时仍可切换标签，自定义快捷键的修改也无需重启即可生效。

+- 修复：目录路径含空格或 Shell 特殊符号时 WSL 文件名搜索失败的问题；取消搜索会停止该次目录扫描。
+- 修复：对齐 macOS 原生窗口按钮与侧栏、设置按钮，并在顶部标签布局中保留窗口按钮所需空间；窗口按钮外观跟随系统。由 [@WilliamWang1721](https://github.com/WilliamWang1721) 在 [#114](https://github.com/Kuddev/pebrel/pull/114) 中贡献。
+- 修复：应用解析为英文时 Git 面板仍保留中文标签的问题。控件、历史时间和应用提示跟随所选语言，切换语言时保留提交草稿和文字选区。由 [@gao-jian-bin](https://github.com/gao-jian-bin) 在 [#118](https://github.com/Kuddev/pebrel/pull/118) 中贡献。
+- 修复：终端忽略用户明确设置的选中文字颜色的问题。未指定选中文字颜色的主题会保留该设置；已明确指定的主题仍保持自身优先级。由 [@Aschenbath](https://github.com/Aschenbath) 在 [#125](https://github.com/Kuddev/pebrel/pull/125) 中贡献。
 
 #### 改进
 
-- 将 Claude Code 的低分辨率图标替换为从 SVG 导出的 1024 像素图像，并按显示尺寸处理 Agent 图标，使标签图标边缘更平滑。
+- 改进：降低文件浏览与文件名搜索的内存占用：输入关键词后才开始递归搜索，复用有容量上限的缓存，并流式查找缓存之外的路径。重复使用文件面板时释放过期结果、取消已被替代的搜索；保留大小写、整词和正则选项，并明确提示搜索未覆盖全部文件或发生错误。
+- 改进：降低背景图内存占用，限制图片加载成本，并在调整窗口大小时复用图像资源；替换背景图会释放旧资源，扩展背景仍保持原有的适配、对齐和文字可读性。

+Windows 提供 Pebrel 安装器和 ZIP 便携包；Linux x64 包以及 macOS Apple Silicon／Intel DMG 继续标记为 Preview。macOS 最低运行版本为 14。分子结构渲染仍处于禁用状态。

+## ADR-0014 — Parallel release validation with one product build graph
+
+- **Date:** 2026-09-14
+- **Context:** The 1.7.0 Windows release job took 41m28s despite a full dependency
+  cache hit. Its logs show three application test compilations (4m44s, 9m16s and
+  4m07s), a 15m08s release build, and 4m16s of additional dependency compilation
+  during packaging. The user requested a slowest-job target of ten minutes.
+- **Decision:** Run the complete Rust workspace with the product interaction
+  feature enabled in one unfiltered invocation. Run native tests independently
+  from package construction; asset aggregation depends on both. Each native
+  platform still runs the complete Python helper and harness suites. Cache keys
+  preserve the existing platform namespace and retain workspace crates. Cargo
+  still validates source, profile and feature fingerprints before reuse.
+- **Product compilation:** The application keeps O3 and Thin LTO and uses 16
+  codegen units to parallelize its large translation unit. Other package settings
+  retain their existing values. Both Windows packagers call one explicit builder
+  for the product and its packaged hook, preserving the same feature graph.
+  Packaging still invokes Cargo and validates source freshness and binary identity.
+- **Contract clarification:** The old packaging test required the literal
+  `--workspace --exclude nebula`, rejecting a valid explicit selection of the two
+  shipped binaries. It now verifies the actual selected packages, binaries and
+  product feature, plus failure propagation and restoration of the caller's target.
+  No test filtering, freshness bypass, size-budget increase or dependency change
+  is part of this decision.
+- **Validation:** The release pipeline runs native tests, packaging fixtures,
+  package-size/identity checks and installed or mounted conformance on all four
+  platforms. Actual job timings determine whether the target is met; cache input
+  changes and first compilation must be reported separately. A configured timeout
+  or parallel scheduling alone is not evidence of a ten-minute successful build.
+- **Revisit condition:** Retain only changes whose complete CI run and package
+  checks pass. Reconsider codegen partitioning if artifact size or runtime
+  measurements regress, and remove redundant caches if restore/save cost grows.

+# Pebrel 1.8.0
+
+## English
+
+### Added
+
+- Added “Focus follows mouse” in Settings → Interaction, off by default, and “Dim inactive panes” in Settings → Appearance, on by default. Both preferences take effect immediately.
+- Added right-click actions to the Shell launcher for choosing the default Shell and, on Windows, opening the selected Shell inside a new administrator Pebrel window.
+- Added Connect, Edit, and Delete to SSH launcher context menus. Delete uses the existing confirmation and undo flow.
+- Added Trae CLI recognition and its tab icon, plus a dedicated Oh My Pi icon.
+
+### Fixed
+
+- Fixed Windows terminal focus consuming `Alt+F4` and `Alt+Space`. `Alt+F4` now uses the normal window-close flow, and `Alt+Space`, followed by `N`, uses the system menu to minimize the window.
+- Fixed the top Settings tab disappearing when switching to another tab. It now remains available until explicitly closed, including when tabs overflow or the tab layout changes.
+- Fixed `Alt+1–9` and `Ctrl+1–9` tab shortcuts losing priority to terminal input. They now work while a terminal or CLI has focus and respect custom shortcut changes without restarting.
+- Fixed WSL filename search failing when the directory path contains spaces or shell punctuation. Cancelling a search stops its own directory scan.
+- Aligned macOS native window controls with the sidebar and Settings buttons, and preserved their reserved space in the top tab layout. Window controls follow the system appearance. Contributed by [@WilliamWang1721](https://github.com/WilliamWang1721) in [#114](https://github.com/Kuddev/pebrel/pull/114).
+- Fixed the Git drawer retaining Chinese labels when the application resolves to English. Controls, history timestamps and application notices follow the selected language; switching languages preserves the commit draft and text selection. Contributed by [@gao-jian-bin](https://github.com/gao-jian-bin) in [#118](https://github.com/Kuddev/pebrel/pull/118).
+- Fixed explicitly configured terminal selection text colors being ignored. Themes without their own selection foreground preserve that setting; themes with an explicit foreground retain their precedence. Contributed by [@Aschenbath](https://github.com/Aschenbath) in [#125](https://github.com/Kuddev/pebrel/pull/125).
+
+### Improved
+
+- Reduced file browsing and filename-search memory use by starting recursive searches only when a query is entered, reusing a bounded cache and streaming paths beyond that cache. Repeated panel use releases obsolete results and cancels superseded searches. Case, whole-word and regular-expression options remain available, with visible feedback for incomplete searches and errors.
+- Reduced background-image memory use with bounded image loading and reuse while resizing the window. Replacing an image releases the previous resources; extended backgrounds retain their fit, alignment and text readability.
+- Replaced the low-resolution Claude Code icon with artwork exported from SVG at 1024 pixels, and prepared Agent icons at their display size for smoother tab edges.
+
+Windows packages include a Pebrel installer and portable ZIP. Linux x64 packages and macOS Apple Silicon/Intel DMGs retain their Preview designation. macOS requires version 14 or later. Molecular structure rendering remains disabled.
+
+## 中文
+
+### 新增
+
+- 新增：在“设置 → 交互”中加入“焦点跟随鼠标”，默认关闭；在“设置 → 外观”中加入“调暗非活动窗格”，默认开启。两项设置均即时生效。
+- 新增：Shell 启动菜单新增右键操作，可设为默认 Shell；Windows 下还可在新的管理员 Pebrel 窗口内打开所选 Shell。
+- 新增：SSH 启动菜单新增“连接、编辑、删除”右键操作；删除沿用已有的确认与撤销流程。
+- 新增： Trae CLI 识别与标签图标，并为 Oh My Pi 加入独立图标。
+
+### 修复
+
+- 修复： Windows 终端获得焦点时吞掉 `Alt+F4` 和 `Alt+Space` 的问题。`Alt+F4` 现在进入正常窗口关闭流程，`Alt+Space` 后按 `N` 可通过系统菜单最小化窗口。
+- 修复：顶部设置标签在切换到其他标签后消失的问题。现在只有主动关闭才会移除，标签溢出或切换标签布局时也会保留。
+- 修复： `Alt+1–9` 和 `Ctrl+1–9` 标签快捷键优先级低于终端输入的问题。终端或 CLI 获得焦点时仍可切换标签，自定义快捷键的修改也无需重启即可生效。
+- 修复：目录路径含空格或 Shell 特殊符号时 WSL 文件名搜索失败的问题；取消搜索会停止该次目录扫描。
+- 修复：对齐 macOS 原生窗口按钮与侧栏、设置按钮，并在顶部标签布局中保留窗口按钮所需空间；窗口按钮外观跟随系统。由 [@WilliamWang1721](https://github.com/WilliamWang1721) 在 [#114](https://github.com/Kuddev/pebrel/pull/114) 中贡献。
+- 修复：应用解析为英文时 Git 面板仍保留中文标签的问题。控件、历史时间和应用提示跟随所选语言，切换语言时保留提交草稿和文字选区。由 [@gao-jian-bin](https://github.com/gao-jian-bin) 在 [#118](https://github.com/Kuddev/pebrel/pull/118) 中贡献。
+- 修复：终端忽略用户明确设置的选中文字颜色的问题。未指定选中文字颜色的主题会保留该设置；已明确指定的主题仍保持自身优先级。由 [@Aschenbath](https://github.com/Aschenbath) 在 [#125](https://github.com/Kuddev/pebrel/pull/125) 中贡献。
+
+### 改进
+
+- 改进：降低文件浏览与文件名搜索的内存占用：输入关键词后才开始递归搜索，复用有容量上限的缓存，并流式查找缓存之外的路径。重复使用文件面板时释放过期结果、取消已被替代的搜索；保留大小写、整词和正则选项，并明确提示搜索未覆盖全部文件或发生错误。
+- 改进：降低背景图内存占用，限制图片加载成本，并在调整窗口大小时复用图像资源；替换背景图会释放旧资源，扩展背景仍保持原有的适配、对齐和文字可读性。
+- 改进：将 Claude Code 的低分辨率图标替换为从 SVG 导出的 1024 像素图像，并按显示尺寸处理 Agent 图标，使标签图标边缘更平滑。
+
+Windows 提供 Pebrel 安装器和 ZIP 便携包；Linux x64 包以及 macOS Apple Silicon／Intel DMG 继续标记为 Preview。macOS 最低运行版本为 14。分子结构渲染仍处于禁用状态。
