 ## 环境要求
 
 - Flutter SDK: ^3.9.2
 - Android: 8.0+ (API 26+)
-- 仅支持魅族手机（15 系列 ~ 25 系列）
+
+---
+
+## 机型匹配情况
+目前据群友反馈已知：
+- 魅族22无mbattery_charger目录生成，无法实时计算相应百分比，因此已在最近版本去除相关匹配信息
+- 魅族18在后续的版本中关闭了mbattery_log生成，疑似无效，老版本可能支持
+- 最完美的支持版本至少可覆盖魅族20/21系机型（20inf已确认，机型匹配ID已更新）

+## [1.6.0] - 2026-07-20
+
+### ✨ 新增
+
+- **更新日志页面**：内置 `CHANGELOG.md` 渲染，版本历史一目了然
+  - 使用 `flutter_markdown` 解析，支持标准 Markdown 格式
+  - 滚动进度条：实时显示阅读进度，提升浏览体验
+  - 进入页面自动请求 120Hz 高刷新率，滑动更流畅（Flyme LTPO 适配）
+  - 滚动时呼吸动画维持高刷感知，停止后自动恢复省电策略
+
+- **AppBar 菜单重构**：刷新按钮左移，右侧新增三点菜单
+  - `更新日志`：已可用
+  - `深色模式`：占位（1.7.0 实现）
+  - `关于`：占位（1.7.0 实现）
+
+- **原生层高刷控制**：新增 `MethodChannel` 通道，支持 Dart 侧动态申请/释放 120Hz
+  - 进入更新日志页面自动触发
+  - 退出页面自动释放，不影响系统省电策略
+
+### ⚡ 优化
+
+- **UI 拆分**：将 `BatteryHealthPage` 的 UI 部分抽离至独立文件，降低耦合度
+- **动画简化**：移除复合动画控制器（`AnimationController`），改用轻量 `AnimatedOpacity` 控制充电条目显隐
+- **更新日志性能**：缓存 Markdown 渲染结果，避免重复解析
+- **LTPO 适配**：通过进度条微动 + 原生层 `preferredRefreshRate`，解决更新日志页面降频卡顿问题
+
+### 🐛 修复
+
+- 修复更新日志页面因 `ListView` + `shrinkWrap` 导致的 `unbounded height` 渲染异常
+- 修复充电条目动画状态残留导致的显示异常
+- 修复部分 `TextStyle` 中 `color` 与 `foreground` 混用导致的渲染断言错误
+
+### 📊 影响范围
+
+- `battery_health_page.dart`：AppBar 重构，动画简化
+- `battery_data_layout.dart`（新增）：UI 布局抽离
+- `changelog_page.dart`（新增）：更新日志页面
+- `MainActivity.kt`：新增原生高刷控制通道
+- `pubspec.yaml`：新增 `flutter_markdown` 依赖，添加 `assets/CHANGELOG.md`
+
+----
+
+## [1.5.3] - 2026-07-19
+- 新增：机型匹配优化
+
+### ✅ 已确认完美支持
+- 魅族 20 / 20 Pro / 20 INFINITY（基于remaining_cap + status=full联合判断）
+- 魅族 21 / 21 Pro（直接读取learned_cap字段信息）
+
+### ⚠️ 部分支持（测试中）
+- 魅族 18 / 18s / 18 Pro / 18s Pro（日志存在，字段解析适配中）
+- 魅族 16s（需回退原厂固件验证）
+
+### ❌ 确认不支持
+- 魅族 21 Note（星纪团队固件，日志格式乱码无法识别，导致异常）
+- 魅族 22（系统未生成 `mbattery_charger` 目录）
+
+### 📌 说明
+- 适配状态仅针对 BMS 日志可读性，与手机硬件本身无关
+- 部分旧机型（如 16 系）若无日志生成，则无法使用本工具
+- 后续若发现其他机型可用，将持续补充
+
+----
+
+## [1.5.2] - 2026-07-14
+
+### 新增
+- 浪漫雅圆字体，工程内文件为FlymeFont.ttf
+
+### 🎨 UI 优化
+
+- **字体体系重构**：数字全局替换为 FlymeFont（浪漫雅圆），中文保留 HarmonyOS Sans SC
+  - 健康度百分比、容量数值、循环次数、电压/温度读数均使用 FlymeFont
+  - 中文/单位/符号保持 HarmonyOS Sans SC，确保阅读舒适度
+- **温标符号修正**：温度显示由 `°C`（度符号 + C）改为专用字符 `℃`（U+2103），与 FlymeFont 原生适配
+- **容量行视觉权重优化**：
+  - 当前容量与设计容量数字使用 FlymeFont（字号 20，字重 300）
+  - `mAh` 单位改用 HarmonyOS Sans SC（字号 16，字重 500），与 `cycles` 保持一致
+  - 整行颜色统一为 `rgb(95, 95, 95)`，弱化视觉重量，突出健康度大数字
+- **电压/温度极值显示优化**：数值与单位统一使用 FlymeFont，箭头符号保留 HarmonyOS
+
+### 🐛 修复
+
+- 修复 FlymeFont 数字 1 在部分场景下显示为红色的问题（字体内部颜色预设）
+- 修复容量行 `designCap`（设计容量）未正确应用 FlymeFont 的问题
+- 修复部分 `TextStyle` 中 `color` 与 `foreground` 混用导致的渲染断言错误
+- 统一主界面与二级页面状态栏样式
+
+### 📊 影响范围
+
+- `battery_summary.dart`：健康度/循环/容量显示样式重构
+- `battery_info_panel.dart`：电压/温度显示字体统一
+- `charge_detail_page.dart`：数值字体统一
+- `trend_chart.dart`：坐标轴数字字体统一
+
+### 📌 备注
+
+- 本次更新纯 UI 优化，不影响数据读取与计算逻辑
+
+----
+
+## [1.5.0] - 2026-07-09
+
+### 🐛 修复
+- 修复有线充电功率计算单位错误（µV × µA 计算时少除 1000，导致功率放大 1000 倍，属于潜藏bug，外面看不出问题）
+- 修复魅族 21 系列 `learned_cap` 因受 `status=Full` 限制导致容量未及时更新的问题
+- `learned_cap` 优先级提升：在所有状态行中优先匹配，不再局限于 `status=Full`
+
+### ⚡ 优化
+- 有线充电功率显示重构：
+  - 主界面：`≈{实际功率}w/{请求功率}w`（例：`≈30w/65w`）
+  - 二级页面：拆分为“请求档位”（`≈80w/L-10`）和“实际功率”（`≈30w`）两行
+  - USB 慢充保持 `≈7.5w` 不变
+- UI 统一：
+  - 统一主界面与二级页面状态栏背景色
+  - 统一主界面与二级页面 AppBar 背景色为 `Colors.white`
+  - 状态栏图标保持深色（`Brightness.dark`）
