-# 更新日志
-
-## 1.3.1 - 2026-08-16
-
-### 移除
-
-- 移除内置维护模式、相关命令、权限、配置和 LuckPerms 软依赖；维护功能建议使用独立的 Maintenance 插件。
-
-### 调整
-
-- GitHub 仓库迁移至 InfstarMC 组织，并同步更新项目文档与下载地址。
-
-### 升级说明
-
-- 升级时不再读取 `maintenance.yml`；为避免删除管理员数据，服务器目录中的旧文件会原样保留，可在确认迁移完成后手动删除。
-
-## 1.3.0 - 2026-08-05
-
-### 新增
-
-- 按 HuskHomes 的单服逻辑完整实现 TPA 请求、接受、拒绝、忽略、预热、冷却、位置快照、音效与相关权限。
-- 新增维护模式，包括 MOTD、BossBar、登录拦截、白名单、管理员通知和 LuckPerms 异步权限检查。
-- 新增 SkinBridge，可识别 InfstarMC、LittleSkin 与自定义 Blessing Skin Provider，并通过 MineSkin 与 Paper Profile API 同步皮肤。
-- 新增管理模式独立状态存储与玩家功能状态管理。
-
-### 优化
-
-- 按便捷方块、管理、修复与皮肤功能重新整理运行时模块。
-- 完善潜影盒会话保护、TPA 请求队列、配置迁移、数据原子写入与持久化错误处理。
-- 验证兼容 Paper `1.21.11` 与 `26.2`，最终插件保持 Java 21 字节码兼容。
-- 移除实验性的 JEI 配方同步及其版本适配子项目，插件继续通过 Paper 公共 API 兼容支持的服务端版本。
-- 迁移 Paper 弃用 API，并将弃用警告设为构建错误。
-- 统一 HuskHomes 风格的中英文消息、颜色和配置注释。
-
-### 注意事项
-
-- 最低服务端版本为 Paper `1.21.11`，不支持 Folia 或 Fabric 服务端。
-- LuckPerms 为推荐软依赖；未安装时维护模式会在玩家加入后复核绕过权限。
-- SkinBridge 默认关闭，启用前必须配置有效的 MineSkin API Key。
-- 主配置版本为 `2`。
