+# 更新日志
+
+## 1.3.0 - 2026-08-02
+
+### 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、玩家功能状态管理与 JEI 配方同步版本适配。
+
+### 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。
+- 适配 Paper `1.21.11`、`26.1.2` 与 `26.2`，最终插件保持 Java 21 字节码兼容。
+- 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`。

+项目默认构建一个完整插件。玩家常用命令、Vanish 与 TPA 属于核心功能，始终加载并通过权限控制；其他可选功能由 `plugins/EssentialsC/modules.yml` 控制。
 
 | 模块 | 默认状态 | 说明 |
 | --- | --- | --- |
 | `blocks` | 开启 | 便捷方块命令、`/essc blocks` 菜单、潜影盒快捷打开 |
-| `player` | 开启 | 飞行、夜视、发光、治疗、喂食、修复、帽子、自杀、隐身、查询玩家 |
 | `admin-mode` | 开启 | `/essc admin` 管理模式与独立状态保存 |
-| `tpsbar` | 开启 | 插件版 TPSBar，仍受 `config.yml` 中 `tpsbar.mode` 控制 |
+| `tpsbar` | 开启 | 插件版 TPSBar，检测到服务端原生命令时自动避免冲突 |
 | `jei-sync` | 开启 | Fabric / NeoForge JEI 配方同步修复 |
 | `mob-drops` | 关闭 | 末影人掉落控制，默认关闭以保留过去标准版行为 |
 | `maintenance` | 开启 | 维护模式命令、MOTD 替换、登录拦截、白名单和拦截通知 |
 | `skin-bridge` | 关闭 | 查询外置 Yggdrasil profile，并通过 MineSkin 与 Paper Profile API 同步皮肤 |
 
-修改模块开关后可先使用 `/essc reload` 刷新运行期服务与监听器状态。由于 Bukkit 命令表不适合在运行期完整热增删，若模块是在启动时关闭的，对应直连命令可能仍需重启后才会注册；通过 `/essc <子命令>` 入口通常可立即按新的模块状态执行。
+修改模块开关后使用 `/essc reload` 即可刷新运行期服务、监听器和命令门禁。可选模块命令始终注册，模块关闭时会返回统一的停用提示，因此无需为了启用命令重启服务器。
