[0.4.8-rc.1] - 2026-08-18
🚀 新功能
- BitTorrent 下载新增 MSE 协议加密（RC4 双向握手，失败自动回退明文连接），在运营商限速/屏蔽 BT 流量的网络环境下可提升连接成功率
- 新增统一诊断日志：应用内可导出脱敏后的运行日志（自动隐去登录凭证、Cookie、代理密码和本地用户目录）辅助排查问题；同时修复了 BT 后端个别错误会导致后台任务静默失败的问题
🐛 问题修复
- 修复分段下载在自适应收缩线程数后又立即回弹，导致下载速度反复抖动的问题
- 修复通过一次性签名/临时授权链接下载时续传失败的问题
- 改进自动代理选路逻辑，避免直连与代理之间反复切换，并修复断点续传因缓存导致下载进度丢失的问题
⚡ 性能优化
- 优化启动流程：语言包与主题并行加载、加快下载目录文件扫描速度，缩短应用启动等待时间
[0.4.8-rc.1] - 2026-08-18
🚀 Features
- BitTorrent downloads now support MSE protocol encryption (bidirectional RC4 handshake with automatic fallback to a plaintext connection), improving connection success on networks where ISPs throttle or block BT traffic
- Added unified diagnostic logging: you can now export a redacted log bundle from within the app (credentials, cookies, proxy passwords, and local user paths are automatically stripped) to help troubleshoot issues; this also fixes a class of BT backend errors that could silently kill background tasks
🐛 Bug Fixes
- Fixed segmented downloads oscillating in speed after the adaptive segment count shrank and then immediately bounced back
- Fixed resume failures when downloading via one-time signed or temporary authorization links
- Improved automatic proxy route switching to avoid repeatedly flipping between direct connection and proxy, and fixed resumed downloads losing progress due to stale cached responses
⚡ Performance
- Faster app startup: language pack and theme now load in parallel, and directory file scanning is quicker, shortening the wait before the app becomes usable
