+## [3.1.0] - 2026-03-22
+
+### Features
+
+- **Vocal Separation**: Integrate BSRoformer neural vocal separation — automatically isolate vocals from background music/noise before transcription for dramatically better accuracy on music videos and noisy audio.
+- **Vocal Separation**: Add Apple Silicon (Metal) GPU acceleration support for vocal separation on macOS arm64.
+- **Native VAD**: Migrate from browser-based VAD to native binary for 10x+ faster voice activity detection, with reliable support for long videos without loading entire audio buffers into memory.
+- **Anti-Hallucination**: Add multi-layer Whisper hallucination filter — curated blacklists for EN/CN/JP/KR, repetition cleaning (kana floods, phrase loops), and cross-subtitle deduplication using Dice coefficient matching.
+- **Changelog Modal**: Auto-display release notes on first launch after update, with a "What's New" button in the About tab.
+- **Progress**: Tighten end-to-end progress reporting with vocal separation percentage display.
+- **LLM**: Normalize usage metadata across LLM adapters for consistent token tracking.
+
+### Fixes
+
+- **Audio**: Handle non-ASCII file paths in FFmpeg and audio decoder on Windows, fixing EILSEQ errors for users with CJK usernames.
+- **Pipeline**: Pass abort signal through parallel processing for proper cancellation, cap semaphore release to prevent over-release, and fix Gemini token usage aggregation.
+- **Pipeline**: Add WAV parser bounds checking, RFC 4180 CSV parsing, and null safety for Whisper segment text.
+- **Electron**: Security hardening with async I/O and proper resource cleanup.
+- **React**: Fix memo safety, stale closures, unmount guards, and selector stability.
+- **Types**: Unify interfaces, type the IPC contract, and fix config/i18n inconsistencies.
+- **Audio**: Improve vocal separation and compression plumbing.
+
+### Refactor
+
+- **Update Service**: Split 997-line monolith into 7 focused modules (types, GitHub API, app updater, version checker, installer, IPC handlers, orchestrator).
+- **Pipeline**: Harden generation flow with lint cleanup.
+- **Binary**: Extract shared `detectBinaryVersion` utility for reuse across binary managers.

+## [3.1.0] - 2026-03-22
+
+### 新功能
+
+- **人声分离**：集成 BSRoformer 神经网络人声分离——在转录前自动分离人声与背景音乐/噪音，大幅提升音乐视频和嘈杂音频的转录准确率。
+- **人声分离**：新增 Apple Silicon (Metal) GPU 加速支持，macOS arm64 设备可使用 GPU 加速人声分离。
+- **原生 VAD**：从浏览器端 VAD 迁移至原生二进制，语音活动检测速度提升 10 倍以上，可靠支持长视频处理而无需将整个音频缓冲区加载到内存。
+- **反幻觉**：新增多层 Whisper 幻觉过滤器——涵盖中英日韩黑名单、重复清理（假名洪泛、短语循环）以及基于 Dice 系数的跨字幕去重。
+- **更新日志弹窗**：更新后首次启动自动展示版本说明，关于页新增「查看更新」按钮。
+- **进度**：完善端到端进度上报，新增人声分离百分比显示。
+- **LLM**：统一各 LLM 适配器的用量元数据，实现一致的 Token 追踪。
+
+### 修复
+
+- **音频**：修复 Windows 上 FFmpeg 和音频解码器无法处理非 ASCII 文件路径的问题，解决 CJK 用户名导致的 EILSEQ 错误。
+- **流水线**：在并行处理中正确传递中止信号以支持取消操作，防止信号量过度释放，修复 Gemini Token 用量累加错误。
+- **流水线**：新增 WAV 解析器边界检查、RFC 4180 CSV 解析以及 Whisper 片段文本空值保护。
+- **Electron**：安全加固，采用异步 I/O 并确保资源正确清理。
+- **React**：修复 memo 安全性、过期闭包、卸载守卫和选择器稳定性问题。
+- **类型**：统一接口定义、类型化 IPC 通信契约，修复配置/国际化不一致。
+- **音频**：改进人声分离与音频压缩的衔接流程。
+
+### 重构
+
+- **更新服务**：将 997 行单体文件拆分为 7 个聚焦模块（类型、GitHub API、应用更新器、版本检查、安装器、IPC 处理、编排器）。
+- **流水线**：加固生成流程并清理 lint 警告。
+- **二进制**：提取共享的 `detectBinaryVersion` 工具函数，供各二进制管理器复用。
