 # CHANGELOG
 
+## v0.15.2
+
+- 修复首选项文件读取为空时的提示信息
+- 工作区参数增加浏览路径
+
+## v0.15.1
+
+- 新版本正式发布
+
+## v0.15.0
+
+### 项目分支变更
+
+自 v0.15.0 开始, 该项目将全面更换至 WPF 框架, Winforms 版本将不再进行功能更新, 只进行 bug 修复.
+
+整个项目将具有下列分支:
+
+- `dev/wf`: Winforms 版本开发分支, 继承 v0.15.0 之前的内容.
+- `dev/wpf`: WPF 版本开发分支, v0.15.0 之后的内容.
+- `release/wf`: `dev/wf` 的发布分支, 用于保留旧版发布功能.
+- `main`: 最新的稳定发布分支, 也就是现在的 WPF 版本发布分支.
+
+所有的本地开发和 pr 操作均在 `dev` 子分支下进行, 确认无误后再合并到对应的发布分支进行发布.
+
+### 项目结构变更
+
+粗略的将一些功能模块划分为独立的库项目:
+
+- `SpineViewer`: 项目主体, UI 和程序逻辑
+- `Spine`: 对不同版本 Spine 运行时的封装库, 提供所有必需操作的统一接口
+- `SFMLRenderer`: 一个 WPF 控件, 支持渲染 SFML 内容
+- `SpineRuntimes/*`: 官方不同版本的运行时库, 部分版本在官方基础上有修改和扩展
+- `NLog.Windows.Wpf`: NLog 在 WPF 上的扩展库 (尚未完工)
+
+每个项目的具体内容见各自的 README 文档.
+
+### 功能变更
+
+目前 v0.15.0 仅为 pre-release, 功能尚未完全迁移, 有以下功能变化和预期计划:
+
+- 完善了全屏查看功能. 快捷键 F11 可快速切换全屏/窗口模式, 并且支持全屏模式下, 鼠标移动至边缘唤出操作面板.
+- 增加了浏览面板. 支持打开文件夹进行浏览, 可以对指定文件夹下所有模型生成预览图进行查看.
+- 支持复制指定模型的参数, 并且可以一键应用到多个模型上, 无法应用的项会忽略.
+- 导出功能进行了精简. 分为 4 种类型的导出, 且减少了参数项, 仅保留常用参数.
+- 导出方式变化. 导出方式变为直接对选中项然后右键菜单进行导出, 不再受 "显示" 和 "仅渲染选中" 参数影响.
+- 版本转换功能将暂时不在新版本中提供, 旧版本中已有的功能仍然可用.
+- 未来将增加动态桌面功能.
+
+## v0.12.13
+
+- 导出文件名增加额外的随机字符串
+
+## v0.12.12
+
+- 修复 2.1 版本遗漏的 SkinnedMeshAttachment 附件渲染

-More versions are under development :rocket: :rocket: :rocket:
+The program is organized into a left-right layout:
 
-## How to Use
+* **Left Panel:** Functionality panel.
+* **Right Panel:** Preview display.
 
-### Importing Skeleton Files
+The left panel includes three sub-panels:
 
-There are three ways to import skeleton files:
+* **Browse:** Preview the content of a specified folder without importing files into the program. This panel allows generating `.webp` previews for models or importing selected models.
+* **Model:** Lists imported models for rendering. Parameters and rendering order can be adjusted here, along with other model-related functionalities.
+* **Display:** Adjust parameters for the right-side preview display.
 
-- Drag and drop or paste the skeleton file/directory into the model list.
+Hover your mouse over buttons, labels, or input fields to see help text for most UI elements.
-- Batch open skeleton files from the File menu.
-- Select a single model to open from the File menu.
 
-### Adjusting the Preview
+### Skeleton Import
 
-The model list supports context menus and some shortcuts, and you can multi-select to adjust parameters in bulk.
+Drag-and-drop or paste skeleton files/directories into the Model panel.
 
-In addition to using the panel for parameter settings, the preview screen supports several mouse actions:
+Alternatively, use the right-click menu in the Browse panel to import selected items.
 
-- Left-click to select and drag models; hold the `Ctrl` key for multi-selection (which is synchronized with the list on the left).
+### Content Adjustment
-- Right-click to drag the overall view.
-- Use the mouse wheel to zoom in and out.
-- “Render Selected” mode: in this mode, the preview screen only shows the selected models and the selection state can only be changed from the list on the left.
 
-The buttons below the preview allow you to adjust the timeline, acting as a simple media player.
+The Model panel supports right-click menus, some shortcuts, and batch adjustments of model parameters through multi-selection.
 
-### Exporting the Preview
+For preview display adjustments:
 
-Exporting follows the “What You See Is What You Get” principle – the preview exactly reflects the output.
+* **Left-click:** Select and drag models. Hold `Ctrl` for multi-selection, synchronized with the left-side list.
+* **Right-click:** Drag the entire display.
+* **Scroll wheel:** Zoom in/out. Hold `Ctrl` to scale selected models.
+* **Render selected-only mode:** In this mode, the preview only shows selected models, and selection status can only be changed via the left-side list.
 
-There are several key parameters for export:
+The buttons below the preview display allow time adjustments, serving as a simple playback control.
 
-- Render Selected Only: This option affects both the preview and export. If enabled, only the selected models will be considered during export while ignoring the others.
+### Content Export
-- Output Folder: This parameter is optional in some cases. If not provided, the output files will be saved in each model’s own folder; otherwise, all outputs will be saved to the specified folder.
+
-- Single Export: By default, each model is exported separately (i.e., batch operation on the model list). If “Single Export” is selected, all the exported models will be rendered on the same canvas, producing only one output file.
+Export follows the **WYSIWYG (What You See Is What You Get)** principle, meaning the preview display reflects the exported output.
+
+Use the right-click menu in the Model panel to export selected items.
+
+Key export parameters include:
+
+* **Output folder:** Optional. When not specified, output is saved to the respective model folder; otherwise, all output is saved to the provided folder.
+* **Export single:** By default, each model is exported independently. Selecting "Export single" renders all selected models in a single frame, producing a unified output.
+* **Auto resolution:** Ignores the preview resolution and viewport parameters, exporting output at the actual size of the content. For animations/videos, the output matches the size required for full visibility.

 ## 使用方法
 
+### 如何修改显示语言
+
+窗口菜单的 "文件" -> "首选项..." -> "语言", 选择你需要的语言并确认修改.
+
+### 基本介绍
+
+程序大致是左右布局, 左侧是功能面板, 右侧是画面.
+
+左侧有三个子面板, 分别是:
+
+- **浏览**. 该面板用于预览指定文件夹的内容, 并没有真正导入文件到程序. 在该面板可以为模型生成 webp 格式的预览图, 或者导入选中的模型.
+- **模型**. 该面板记录导入并进行渲染的模型列表, 可以在这个面板设置与模型渲染相关的参数和渲染顺序, 以及一些与模型有关的功能.
+- **画面**. 该面板用于设置右侧预览画面的参数.
+
+绝大部分按钮或者标签或者输入框都可以通过鼠标指针悬停来获取帮助文本.
+
 ### 骨骼导入
 
-有 3 种模式导入骨骼文件:
+可以直接拖放/粘贴需要导入的骨骼文件/目录到模型面板.
 
-- 拖放/粘贴需要导入的骨骼文件/目录到模型列表
+或者在浏览面板内右键菜单导入选中项.
-- 从文件菜单里批量打开骨骼文件
-- 从文件菜单选择单个模型打开
 
-### 预览内容调整
+### 内容调整
 
-模型列表支持右键菜单以及部分快捷键, 并且可以多选进行模型参数的批量调整.
+模型面板支持右键菜单以及部分快捷键, 并且可以多选进行模型参数的批量调整.
 
 预览画面除了使用面板进行参数设置外, 支持部分鼠标动作:
 
 - 左键可以选择和拖拽模型, 按下 `Ctrl` 键可以实现多选, 与左侧列表选择是联动的.
 - 右键对整体画面进行拖动.
-- 滚轮进行画面缩放.
+- 滚轮进行画面缩放, 按住 `Ctrl` 可以对选中的模型进行批量缩放.
 - 仅渲染选中模式, 在该模式下, 预览画面仅包含被选中的模型, 并且只能通过左侧列表改变选中状态.
 
 预览画面下方按钮支持对画面时间进行调整, 可以当作一个简易的播放器.
 
-### 预览内容导出
+### 内容导出
 
 导出遵循 "所见即所得" 原则, 即实时预览的画面就是你导出的画面.
 
+在模型面板里, 右键菜单可以对选中项进行导出操作.
+
 导出有以下几个关键参数:
 
-- 仅渲染选中. 这个参数不仅影响预览模式, 也影响导出, 如果仅渲染选中, 那么在导出时只有被选中的模型会被考虑, 忽略其他模型.
 - 输出文件夹. 这个参数某些时候可选, 当不提供时, 则将输出产物输出到每个模型各自的模型文件夹, 否则输出产物全部输出到提供的输出文件夹.
 - 导出单个. 默认是每个模型独立导出, 即对模型列表进行批量操作, 如果选择仅导出单个, 那么被导出的所有模型将在同一个画面上被渲染, 输出产物只有一份.
+- 自动分辨率. 该模式会忽略预览画面的分辨率和视区参数, 导出产物的分辨率与被导出内容的实际大小一致, 如果是动图或者视频则会与完整显示动画的必需大小一致.
